The Prime Minister has officially begun the race to

the next general election, kicking off six weeks

of campaigning and pledges from all parties on

what we can expect if we vote to make them the

next government.

Whichever party you support, and whoever ends up

getting the keys to Number 10, housing and construction

needs to be a key focus for the country going forward.

With the economy still struggling, the construction industry

accounts for around 6% of UK GDP, making it instrumental

in propelling economic growth and a section of the country

that should not be ignored.

Despite this, it feels like housing issues have been largely

neglected in recent years. We’ve had 16 housing ministers

in the last 13 years, with some spending just a few weeks in

office. This constant shuffling surely makes it difficult for any

of them to really get a grip on the issues we all face, and not

surprisingly the government’s target of 300,000 new homes

a year hasn’t been met this century.

That’s why we’ve decided to take an in-depth look at

offsite manufacturing this month, since these modern

methods of construction have been much touted as a

tangible way that we could work towards achieving these

targets.

General election ‘a pivotal opportunity’ for UK housing policy

Construction industry associations have

hailed the upcoming general election as

a pivotal moment for the future of the

UK’s housing policy, and an opportunity

to put sustainable housing at the top of

the political agenda.

Andrew Carpenter, Chief Executive

of the Structural Timber Association

(STA), said: “We urge all political parties

to seize this chance to revolutionise

the way we build our homes. Housing

is a crucial issue for voters across

the country, but it’s essential that

we underline the importance of

sustainability.”

The STA is urging all political parties

to prioritise sustainable housing

solutions, such as timber frame

construction, to revolutionise the

way we build and ensure a greener

and more efficient future. Andrew

concluded: “[We need to] continue the

momentum that has been garnered

by the Timber in Construction Policy

Roadmap, published in December last

year.”

Meanwhile, Fiona Hodgson, Chief

Executive of the Scottish and Northern

Ireland Plumbing Federation (SNIPEF),

has urged politicians to focus on

developing a skilled and productive

Proctor Air has been issued with a

BBA certificate in verification that the

membrane performs as claimed.

Proctor Air is a roofing membrane

from A. Proctor Group that simplifies

pitched roof construction thanks to

being both air and vapour permeable.

Its water holdout performance and wind

uplift resistance ensures it can cope

with the more frequent bouts of extreme

weather driven by climate change.

Iain Fairnington, Technical Director

at A. Proctor Group, said the company

advocates working with certification

bodies such as the British Board

of Agrément to bring new product

technologies to the market. He said:

“An Agrément certificate assesses

a construction product’s fitness for

purpose. Having a BBA certificate for

Proctor Air shows we have had the

product tested and assessed in relation

to its intended use.”

Certification showing that a thirdparty

has tested and verified the

performance of a product gives the

workforce to ensure the UK remains

competitive.

She said: “This election presents

a crucial opportunity for our political

leaders to commit to policies that not

only ignite economic growth, but also

foster a skilled workforce essential for

national prosperity and enhancing social

mobility.”

The UK goes to the polls on 4 July,

2024, against a continuing backdrop

of falling housebuilding rates, despite

recent positive growth in the general

construction sector.

Proctor Air receives BBA certificate

construction industry confidence that a

manufacturer’s claims are genuine and

accurate.

Proctor Air has an Sd value of

0.015m and a vapour resistance of

0.075MNs/g. It is an air permeable

low resistance (APLR) underlay, which

provides a more uniform flow of air

through the roof space than normal

vents.

The S&P Global/CIPS UK

Construction PMI data for April showed

the fastest reduction in residential

building work since January 2024.

Brian Berry, Chief Executive of the

Federation of Master Builders (FMB),

said: “The UK is currently experiencing

a housing crisis and a crisis in

construction skills and training. If we

are to achieve sustainable long-term

growth, it is vital both house building

and employment rates are prioritised.

Politicians need to take note of the

bigger picture beyond the headlines.”

BCIA supports

Carers UK

The Building Controls Industry

Association (BCIA) has chosen Carers

UK as its nominated charity for

2024. The organisation will be asking

members to plan corporate activities

throughout the year as part of an

ongoing fundraising initiative.

Two out of three people in the UK

will become carers at some time in

their lives. Current statistics show

around five million UK residents are

carers, and every day another 6,000

people take on a caring responsibility.

Carers UK provides help and support

for carers across the UK, working with

both local communities and large-scale

associations.

BCIA president Stacey Lucas said:

“So many people are touched by the

need to care for a loved one, or will

likely be in the future, so I feel this is a

charity that speaks to all.”

Building Levy ‘could threaten housing delivery’

LATEST NEWS

The introduction of the Building Safety Levy across Scotland,

as well as in England, could threaten housing delivery and

lead to the loss of SME housebuilders and developers, new

research suggests.

This comes as Scotland prepares to follow the UK

government’s lead in implementing a Building Safety Levy,

similar to the levy introduced in England under the Building

Safety Act 2022, which is expected to bring in around £3bn in

revenue over 10 years. However, recent research of 100 UK

housebuilders, commissioned by Polypipe Building Products,

found that over half (56%) say that the levy, which will enforce

larger contributions to planning authorities for remediation

work, will create a barrier to future housing delivery.

Furthermore, 62% believe the levy will deter people from

joining the industry and almost two-thirds (65%) believe the

levy will also lead to the loss of more existing businesses.

The concern is that, amidst a difficult housing market and

the need to adapt to a changing regulatory landscape, firms

will be expected to make larger contributions to address

previous building safety defects.

However, the research found that half (51%) of UK

housebuilders do not believe that the Building Safety Act

will affect them. While the legislation does principally focus

on Higher-Risk Buildings (HRBs), which are classified as

residential blocks of 18m tall or seven storeys high, with

two or more residential units, the Act applies to work on all

residential dwellings.

Therefore, in addition to the introduction of the new levy,

there are also implications on the type of insurance and

warranties that housebuilders and developers will need to

take out. Under the Act, newbuild warranties will increase

from 10 to 15 years from the date of purchase and must

be provided to freehold purchasers with a lease of 21 years

or over. The warranty will not only apply to newbuilds, but

also to refurbishments and conversions, which must also be

backed by insurance.

Despite the challenges, the industry does not oppose the

new measures. In fact, 59% of housebuilders say that despite

the challenges ahead, they encourage any reform that will

ensure safety hazards in buildings are eliminated.

Hayley Hayes, Head of Specification at Polypipe Building

Products said: “Building safety legislation, and the protection

of homeowners and residents, is of the utmost importance to

the housebuilding industry. However, while the industry backs

reform to enhance this, many also share concerns about

what the legislation means for their future.

“The UK housing sector is facing numerous challenges

and, to navigate this difficult landscape, local governments

and the wider supply chain need to support housebuilders

and developers in complying with updated regulations while

working towards ambitious sustainability targets – all while in

a difficult economic climate.”

Overall, the research found that there is widespread

misunderstanding around some elements of the Building

Safety Act, with over half labelling the gateways as

‘confusing’ and ‘unclear’ and almost two thirds (65%) of

housebuilders saying that meeting the legislation will be

‘extremely challenging’.

Hayley continued: “While we all want to build safely, it is no

surprise that many firms are facing uncertainty and there is

clear confusion around some of the legislation. With a rapidly

evolving regulatory landscape, businesses require support,

education and access to good quality product information

and resources to help them remain abreast of the changes

and ensure compliance. Trade bodies, places of education,

employers and manufacturers all need to do their bit to aid

the transition.”

Glazing Summit goes from strength to strength

The Glazing Summit is returning

Concerns grow over the best way forward as the

UK seeks to decarbonise domestic heating

The Department for Energy Security

and Net Zero (DESNZ) has announced

that its planned Hydrogen Heating Town

pilot of 10,000 homes will not take place

before 2026. The scheme was originally

intended to test the use of hydrogen in

residential heating and cooking.

In a statement, DESNZ said: “The

government has decided not to

progress work on a hydrogen town pilot

until after 2026 strategic decisions on

the role of hydrogen in decarbonising

heat. This follows careful consideration

of the future of the work in light of the

decision in December 2023 not to

proceed with the hydrogen village trial in

Redcar.

“We believe that low carbon

hydrogen may have a role to play in heat

decarbonisation, alongside heat pumps

and heat networks, but in slower time in

some locations.”

Commenting on the decision, David

Cowdrey, Director of External Affairs

at the MCS Foundation, said: “We

welcome the decision to suspend the

hydrogen town project. Today’s decision

confirms that heat pumps and lowcarbon

heat networks are the only viable

solution for decarbonising heating at

scale. Heat pump installations in the UK

have been growing in the last few years,

but we need long-term policy certainty

to ramp up the market.”

Kensa Group CTO, James Standley,

added: “Halting the development of a

hydrogen village is further recognition

that the technology has no major

role to play in future home heating.

Every academic study on the issue,

the economics and the physics

demonstrates this, and the government

should now take the next logical step

and rule out hydrogen heating for

anything other than a small number of

very specific cases.”

In a separate statement, the

Public Accounts Committee (PAC)

has published its own report into the

decarbonisation of home heating. The

report says this issue is one of the

biggest challenges to the government

achieving net zero, but PAC says it is

not convinced by the progress that has

been made towards the government’s

goal of 600,000 heat pump installations

per year.

The report says consumers still face

“too much complexity and confusion

to make informed decisions about

installing a heat pump, including

understanding whether they need

insulation upgrades to manage their

heating bills”.

The report continues: “DESNZ faces

a substantial challenge to increase the

number of trained heat pump installers

to support an elevenfold increase in

heat pump installations. It needs to

be realistic about levels of consumer

demand, raise public awareness of heat

pumps and work with industry to make

heat pumps more affordable.

“It is important that no one is left

behind in the transition to low-carbon

heating, yet DESNZ is still to work

out how it will support households to

decarbonise their homes where heat

pumps are not a practical solution.

Low-carbon heating will need to

be supported by reliable and green

sources of energy. Indecision over the

role of hydrogen for heating is creating

uncertainty.”

The PAC report comes as new

research carried out by YouGov for the

Energy & Utilities Alliance found just 10

per cent of UK adults surveyed said

they either have a heat pump or want to

get one.

Value sales down for

builders’ merchants

as year begins

Builders’ merchants’ value sales were

down -4.7% in February compared to

the same month a year ago, according

to the latest Builders Merchant Building

Index (BMBI) report. Volume sales

dropped -7.5%, while prices increased

+3.1%. With an extra trading day this

year, like-for-like sales were down

-9.2%.

Year-on-year, eight of the 12

categories monitored by the BMBI

sold more than in February 2023 with

Workwear & Safetywear (+18.3%) being

the leading category. Miscellaneous

(+10.2%) and Decorating (+6.2%) also

did better than merchants overall. But

two of the largest categories – Timber

& Joinery Products (-6.4%) and Heavy

Building Materials (-7.9%) - were down.

Renewables & Water Saving (-20.9%)

was the weakest category.

However, in February total value

sales increased +4.8% compared to

January 2024. Volume sales increased

+8.1% and prices were down -3.1%.

With one less trading day in February,

like-for-like sales were up +9.7%. Eight

of the categories sold more monthon-month

with Landscaping (+17.0%)

well ahead of the rest. Heavy Building

Materials (+5.8%) and two small

categories, Renewables & Water Saving

(+7.1%) and Services (+6.6%) did better

than total merchants. Plumbing Heating

A picture of health: why it’s easy to be passionate about

the UK’s offsite sector

Confidence in modular and offsite construction has been dented in the last year. But should the

challenges faced in delivering volume housebuilding via modern methods of construction (MMC)

impact on the positives to be found elsewhere in the sector? Adam Salt, Business Development

Manager North for A. Proctor Group, reflects on some of the success stories he encounters in a

buoyant marketplace.

The offsite sector has undoubtedly faced issues – specifically

in the housing sector, with a number of high-profile

manufacturers ceasing operations in 2023. Specific factors can

be attributed to each individual case, though it’s possible to

draw some broad conclusions.

Delivering traditional housing developments required

organisations to plan for, and finance, a scale of production

that isn’t yet there. Those financial risks were compounded by

delays in purchasing land and securing planning permissions.

Yet it remains fundamentally true that the speed and quality

made possible by MMC is demonstrated every day in the

delivery of other buildings. Whether it’s high-rise residential,

schools, hospitals, warehouses or prisons, there is real

momentum to turn MMC into BAU (business as usual).

government to try and affect positive change. And perhaps the

most significant result of that collaboration is the Construction

Playbook, published at the end of 2020.

The playbook sets how government will work with industry

to deliver public projects more efficiently, with a particular

focus on getting projects and programmes “right from the

start”. Not only is this a positive in itself, but changes and

improvements evidenced in public procurement usually start

to become the norm throughout construction.

Promoting the adoption of construction platforms

A key goal of the Construction Playbook is to procure more

projects using construction platforms. These are “standardised

and interoperable components and assemblies”, where

manufacturers can offer a ‘kit of parts’ for use with a common

UK construction is setting an example that others want

to follow

My colleagues and I talk to people all over the world

about modular and offsite construction methods. Those

conversations have made one thing particularly clear: the UK

is pretty good at this!

Some construction companies in the United States, for

example, are just starting to grasp the potential, and they see

the UK almost like pioneers. But that picture isn’t necessarily

reflected here at home.

When failures in MMC-delivered housing are reported in

the wider media, they continue to link modern housing to

the flawed prefab and non-traditional housing of yesteryear.

Rather than being elevated by success stories, the sector is

instead weighed down by continual comparisons to past

failures.

Encouraging positive change from the top down

Arguably the biggest success story is that the wider

construction industry has collaborated with the UK

structural solution. As shorthand, platform construction is often

compared to modern automotive assembly techniques.

One of the earliest examples of a fully realised construction

platform is Seismic. We supplied our Wraptite ® external air barrier

system to the Northampton School for Boys Multi-Academy Trust,

which was a Department for Education-funded project that used

Seismic’s technology.

A key advantage of Seismic, and platforms generally, is the speed

and efficiency with which buildings can be ‘assembled’ (rather than

‘constructed’) thanks to the repeatability offered by the system

design. Products specified for use with such systems need to work

within that environment, rather than risk slowing things down.

The self-adhered nature of the Wraptite membrane did just that,

providing vapour permeability and airtightness in a single layer. It

saved on labour and material costs, and contributed to overall

building performance goals.

Supporting panelised and volumetric offsite solutions

Product platforms represent an exciting future for the construction

industry, and are backed by government procurement guidance.

Of course, modular solutions like panels and volumetric systems

remain an important part of the landscape. Indeed, they are often

still the first thing people think of when talking about modular,

offsite or MMC.

Here again, Wraptite offers a significant benefit. Its vapour

permeability allows moisture out of the construction, helping the

panel to dry out. And the self-adhered nature of Wraptite protects

finished products during transportation too.

The majority of membrane solutions are taped, meaning they

are not fully bonded to the substrate. During transport, lateral

air movement across the surface pulls at the membrane, tearing

it and potentially damaging the panel. That doesn’t happen when

Wraptite is used.

Working with the offsite sector to offer bespoke solutions

These are all important features of a single product in the A.

Proctor Group range, and they can be taken advantage of by any

offsite or modular manufacturer.

Where we really work best, however, is engaging with manufacturers

individually and finding ways in which we can help to improve

processes. Collaboratively, we look at the manufacturing, storage

and transport stages to find the right solution for any given system.

This collaboration is what gives us such optimism in the offsite

sector, because we’re working with system manufacturers every

day and seeing the outcomes of their efforts. Exciting innovations,

like developing robotics to apply membranes in the factory, show

that offsite construction is not sitting still. And we are proud to

support, and work with, such developments.

While the offsite/modular sector is delivering exciting schemes

across the country, it is still grappling with two particular challenges:

storage and transport.

When panels are completed in the factory, they are typically shrink

wrapped. The materials used to make the panel naturally contain

moisture, but rather than being able to dry out during storage, the

wrapping traps moisture within the system.

Our Wraptite membrane might be the right solution for you, but

it is not our only solution. To find out more about our membranes

for offsite and MMC, and to find out how we can work with you

REVITALISING THE URBAN

LANDSCAPE

The Technique project in London has

used the benefits of a hybrid structural

timber and steelwork solution –

delivered by B&K Structures – to

revitalise the urban landscape while also

achieving excellent efficiency ratings.

Technique is the unique commercial redevelopment of

two adjoining mid-20 th century properties, located in

Clerkenwell, London. It has harmonised and extended

the development’s useable space in a way that offers flexibility

in its new commercial role, while simultaneously achieving

outstanding levels of sustainability. The unification of the two

outdated industrial buildings has created three attractive new

floors, which helped achieve the ambitious financial, practical

and environmental goals for this building.

Working with developer General Projects, the client set out

to deliver a development encapsulating high standards of

architecture and specification, which would minimise any

waste of energy and resources. The result is a BREEAM

Excellent rated building that has received wide acclaim for its

attractive remodelling, using exposed engineered timber as an

extensive part of its appeal.

The integrated package was delivered by specialist timber

subcontractor B&K Structures in collaboration with suppliers

Binderholz (which supplied the CLT) and Derix (which

supplied the Glulam). The quality and accuracy of the off-site

manufacturing methods, combined with advanced scheduling

and site erection tools, helped the build program meet its

deadlines, while the use of timber meant lorry deliveries were

cut by up to 70% – key for a site where space and complexity

presented significant challenges.

By using timber the team was able to navigate a complex

planning process and maximise the area uplift on a retained

RC structure with serious existing limitations.

Amr Asaad of B&K Structures says: “There were initial benefits

[to using timber] such as the lower weight requiring far less

reinforcement of the foundations, and the enhanced future

flexibility it provides in terms of adapting the building to different

needs.”

Fred Schwass, Development Director at General Projects,

adds: “Our team has worked together as pioneers in mass

timber, delivering unique spaces which prioritise quality and

aesthetics over lettable space. For Technique we were able to

ensure cost certainty on the structural elements, meaning we

had a pain/gain share agreement so the client had reasonable

cost certainty during construction.”

The dedication to an aesthetically pleasing finish using low

environmental impact materials is clear to see throughout the

building. The exposed structure celebrates the building by

transposing a new CLT frame with the same grid, while

the timber slabs provide future

tenants with the flexibility to

connect floors with staircases if

required at a later date.

Lee Roberts, Pre-Construction

Director at B&K Structures, concludes:

“Technique is another fantastic addition to our commercial

portfolio and showcases the benefits that a hybrid timber and

steel solution can bring to complex refurbishment projects.

The faultless design and build process by the BKS team is

testament to our longstanding experience and expertise with

this type of scheme.”

Sustainability and low carbon targets were crucial to the

measured success of the project, and this was a key

consideration throughout. In total, the 648.38 cubic metres

of engineered timber supplied for the redevelopment carry

100% PEFC chain of custody and offer maximum points at

MAT03 of BREEAM, while the greenhouse gases stored during

its growth amount to 484.3 tonnes of CO 2

e. Thanks to the

responsible management of European forests where the trees

were sourced, from cradle to grave, the 374 Kg CO 2

e/m 2

figure exceeds RIBA 2030 targets and equates to LETI Band

A. Furthermore, as the timber was sourced from sustainably

managed European forests, it can be shown to have regrown

in just 142 seconds.

The CLT used is formaldehyde-free and the adhesives in the

timber Glulam conform to EN 301, formaldehyde class E1 –

giving maximum points at BREEAM EA02 – contributing to

Technique earning a BREEAM Excellent rating.

The Technique development is a ground-breaking example of

innovative commercial redevelopment. In essence, Technique

not only revitalises the urban landscape through sustainable

redevelopment, but also exemplifies a harmonious blend of

architectural innovation and sustainability. As a pioneer in

mass timber construction, it sets a strong precedent for future

developments to follow.

CLAY BRICKS BUILD PROPERTIES

THAT STAND THE TEST OF TIME

Designed to withstand extreme weather, changing climates and even architectural

trends, clay bricks are a building material for the ages that can retain their

structural integrity for more than 150 years. That’s why buildings constructed from

this enduring material are such a desirable asset, according to the Brick

Development Association.

Companies building

commercial properties

need to create a structure

that will hold its value

and be low maintenance.

That’s why clay brick continues to be so

popular among specifiers and architects

working on commercial buildings – as

it’s a style that has dominated the UK’s

architectural landscape for hundreds of

years. Walk down any street and there

will be buildings made of clay brick,

whether they come from the Georgian,

Victorian or post-war eras – clay brick is

never out of fashion.

Strength and durability

Testimony to its timeless appeal, clay

brick is highly durable and can last

for centuries, reducing the need for

frequent repairs and replacements.

With a minimum active lifespan of 150

years, clay brick’s appearance remains

consistent throughout its active life and

the bricks won’t fade in comparison to

other construction materials – in fact,

brickwork weathers well resulting in

buildings becoming more attractive.

Unlike render, timber or other building

materials which require regular

maintenance, clay brick’s resilience

minimises its environmental impact. Noncombustible,

clay brick façades often

survive fires structurally intact, enabling

their renovation and reuse.

Walk down any UK

street and there will be

buildings made of clay

brick, whether they

come from the

Georgian, Victorian or

post-war eras - clay

brick is never out of

fashion.

Unmatched adaptability

Clay brick’s classic beauty and durability

is matched by its versatility, making

it an ideal building material for both

commercial and domestic properties

of any style and era. With its wide

selection of colours, textures, shapes

and sizes, clay brick allows for immense

creativity and flexibility in design. Some

brick products have colours applied

to the faces of the brick or paver to

create a unique effect or finish, and it

can be easily adapted for extensions,

renovations or changes in use as time

progresses.

Clay brick also pairs beautifully with

many other building materials and

systems, and can be deconstructed and

rebuilt to create exceptional brickwork

features and detailing. New clay brick

products provide even more options

and include thin joint mortar brickwork,

brick slips, clay thermal blocks and thin

bricks mounted on insulated backings.

Ongoing innovations in the industry

ensure that clay brick continues to offer

new possibilities for creative design and

durable construction, no matter the

needs of the client.

Reduce energy consumption

Beyond their enduring aesthetic, clay

bricks also provide ongoing benefits

through energy efficiency – something

that is increasingly important for

commercial building owners to consider

during both construction and retrofit

projects.

Noted for its excellent thermal mass,

clay brick’s ability to absorb, store and

release heat energy helps to regulate

indoor temperatures and reduce energy

consumption for heating and cooling.

This contributes to lower operational

carbon emissions, because the building

requires less energy to maintain

comfortable temperatures throughout

the year. While a clay brick building

will stand the test of time, its energy

performance also makes it an investment

that pays dividends through energy

savings.

Clay brick’s peerless blend of

sustainability, adaptability and endurance

will ensure this quintessential building

material remains an architectural

mainstay that will be valued by architects

and property owners for generations to

come.

Transforming Battersea Power Station

Battersea Power Station is one of the most iconic brick-built structures in London. This decommissioned coal-fired

power station was built in two stages, starting in 1929 and ultimately completed in 1955, with construction having

been paused due to World War Two. Fully decommissioned by 1983, the whole structure was given Grade II-listed status

in 1980 and upgraded to Grade II* in 2007. The building remained largely empty until 2014 but has now been transformed

into one of central London’s largest new developments.

The £9bn redevelopment project has seen this 42-acre former industrial brownfield site become home to a mixed-use

residential and commercial community of homes, shops, bars, restaurants, cafes, offices and more than 19 acres of public

space. The site is serviced by a Zone 1 extension to the London Underground Northern Line and the restoration of the

Grade II* listed Power Station.

The overall project has been divided into eight phases, with each designed by a range of specialist architects. These

include SimpsonHaugh and Partners and De Rijke Marsh Morgan (dRMM) in Circus West Village (Phase 1), WilkinsonEyre

in Battersea Power Station (Phase 2), and Foster + Partners and Gehry Partners in The Electric Boulevard, Battersea Roof

Gardens and Prospect Place, (Phase 3).

The first chapter of the development, Circus West Village, was completed in 2017 and is now home to over 1,800

residents, as well as a mix of bars, restaurants and leisure facilities, including a cinema and theatre.

The Power Station was the second phase to open to the public on 14 October 2022. This truly mixed-use building is home

to Apple’s London Campus, hundreds of new shops housed in the historic turbine halls, a cinema, a 24,000ft 2 food hall, a

glass chimney lift and hundreds of new homes.

When the development is completed 25,000 people will live and work in the area, creating one of London’s largest

office, retail, leisure and cultural quarters. Across the 42-acre site a new 24/7 community will be formed with over 250

shops, cafes and restaurants, theatre, hotel, medical centre and 19 acres of public space including 450 metres of river

frontage and a six-acre public park. Battersea Power Station itself will be a new office district with more than 3 million ft 2 of

commercial space alongside new private and affordable homes.

TIMBER FRAME INGENUITY HELPS

TRANSFORM REGENERATION SITE

Brooks Dye Works, a regeneration scheme in Bristol, is one of the latest developments to

benefit from Taylor Lane Timber Frame’s design expertise and product innovation.

Brooks Dye Works, based in St

Werburghs, Bristol, is a new

housing development comprising

113 one, two, three and four-bedroom

homes. The site centres around the

restored iconic chimney, with each

property offering open plan, flexible

living with parking and access to outside

space. The former Brooks Laundry dates

to the 19 th century when the site was

used for industrial units by Brooks Dyers

and Cleaners.

Developer Acorn Property Group worked

with Hereford-based Taylor Lane Timber

Frame on the project, using both its

advanced wall system and prefabricated

pitched roof cassettes to help reduce

time onsite.

Dave Gittins, Construction Director

for Acorn’s Bristol Region, says:

“Through careful planning, our teams

worked to ensure the scheme aligned

with our ‘different by design’ ethos,

complementing the surrounding area

while also making improvements to

the public realm. Designed for modern

living, the homes have been built with

sustainability in mind, coupled with our

usual high standards of construction

detail and thoughtful interiors.”

Tried and trusted supplier

Acorn appointed sub-contractor

Taylor Lane Timber Frame because

they were impressed by the quality of

their workmanship and the speed and

accuracy associated with timber frame

construction.

Taylor Lane worked with the main

contractor to deliver all 113 properties.

The task was particularly complex at the

design stage and during construction as

the project included some intricate and

site-specific details.

Complex roofs

Taylor Lane had to contend with a variety

of substrates, building up from block and

beam slabs, cast concrete slabs and,

in some instances, over a steel frame

for the underground carpark. Different

tolerances and settlement issues had

to be factored in. Also, some of the

properties were near existing dwellings

so appropriate products and methods

had to be used to ensure compliance,

particularly with fire regulations.

The development includes a mix of two

and three-storey terraced houses and

apartment blocks. Numerous roofs were

designed to accommodate the different

property types, including pitched truss,

cut, and flat roofs. There is a complex fall

design for the apartment roofs.

To ensure the development blends well

with its surroundings some properties

have parapets – a popular and traditional

architectural feature in Bristol.

Offsite construction

reduces build time

Two blocks of six terraced houses

enabled Taylor Lane to showcase its

design skill and one of the many benefits

of offsite timber frame construction.

Each of the 12 properties in that section

features a pitched roof with vaulted

ceilings on the second floor. Taylor Lane

engineered these so that the insulated

roof cassettes could be fabricated

offsite at its factory in Herefordshire and

assembled onsite in around 10 days.

This reduced the build time, minimised

working at height and omitted the

labour-intensive process of insulating

between rafters onsite.

Image from Acorn Property Group

Factory-formed floor cassettes were

made offsite to create roofs for the

apartment blocks. Taylor Lane then

constructed the appropriate falls using

decked cassettes and firring.

Where possible, the roofs were formed

at floor or slab level and lifted to wall

plate level to minimise the requirement

for working at height. Even with

restricted lay-down space, in some

instances, the cassettes could be

installed directly from the lorry bed to

final position, such was the speed of

installation.

The project was managed by Taylor

Lane’s Contracts Manager, Colin Yardley.

As a dedicated site contact, Colin

provided consistency and reassurance

throughout the project.

All the homes at Brooks Dye Works

are now sold and occupied, and

have proven popular among young

professionals and young families.

Improvements were also made to the

public realm, with pedestrian access

to the neighbouring Mina Road Park

extended, opening up routes and

spaces which had been lost since the

1950’s. The new Alfred Brooks square

centres around the restored chimney

and creates a focal point for the

community.

TRUSSED RAFTERS CAN PLAY A KEY

ROLE IN PROVIDING SHELTER

Sue Darbyshire, a designer for Donaldson Timber Engineering, explains why she

believes trussed rafters can bring real benefits to the construction of larger, more

complex buildings such as care homes and student accommodation.

control within the care home, and

contributing to a more comfortable living

environment. This can also help achieve

the requirements of Approved Document

L, which limits air permeability for new

buildings from 10m 3 /hr.m 2 to 8m 3 /

hr.m 2 , along with other key changes to

regulating airtightness.

We often think of trussed rafters

as a simple offsite solution

for individual houses, but the

various benefits they bring, including

offsite manufacturing, quality control

and sustainable materials can also be

applied to much larger, more complex

buildings.

According to Statistica, there are

currently more than 17,000 care homes

in the UK, and we are likely to see a

demand for more as 144,000 additional

care home beds are required to meet

the UK’s population growth in the

next 10 years. These, and other large

residential projects such as student

accommodation, should be considering

trussed rafters as a first-choice

sustainable roofing solution.

Trussed rafters are known for their

quick installation and reduced on-site

construction time, which all translates

to a shorter construction period and

less disruption to the overall project. In

many ways, they are the oldest modern

method of construction (MMC) in use in

the construction industry today – and

the most well understood.

Factory-controlled environments

allow for stricter quality control during

fabrication, ensuring consistency in

quality but also minimising wastage. This

is particularly important in larger projects

such as care homes, where wastage

and minor errors can stack up over time

to stretch budgets to breaking point.

Sustainability

A care home that prioritises resident

comfort and sustainability can be an

attractive choice for those who are

environmentally conscious. Firstly,

including more timber in designs is

an easy way to reduce your carbon

footprint, and trussed rafters help

to achieve this. Timber is the most

environmentally friendly material currently

available, as it has the lowest energy

consumption and the lowest emissions.

Larger buildings can store up to

400% more carbon when built out of

engineered timber products instead of

alternative materials such as concrete.

Sustainably sourced timber that is PEFC

or FSC-certified saves CO 2

emissions,

both through the carbon captured and

stored in the wood product and the

avoidance of energy-intensive materials.

Benefits to residents

While residents may not see the

trussed rafters themselves, the benefits

they bring can contribute to a more

comfortable, efficient, and potentially

healthier living environment. For

instance, a well-designed truss can be

incorporated with insulation materials,

leading to regulated temperature

If you choose exposed beam designs,

trussed rafters can also help create

a better living environment for care

home residents, creating large open

spaces framed by natural materials.

Incorporating natural materials such as

wood and designing spaces with plenty

of natural light and ventilation is all part

of biophilic design principles, which gives

us a connection to nature by bringing

elements of the natural world into our

buildings, improving mental wellbeing

and health.

Plan ahead with your designer

Developers who are looking to have

a timber trussed rafter roof designed

for a care home should involve the

designer as early as possible, to give

them sufficient time to consider the truss

design; and ensure it is suitable for the

overall project.

This is particularly important for

any complex roof design. I was

asked to design a trussed rafter

roof for a purpose-built care home

accommodating 67 residents. The roof

would house complex mechanical and

electrical components, including plant

that needed to be concealed from view.

For such a project, the roof design

needed to prioritise the facilitation of

the plant installation while allowing the

external roof envelope to be covered.

It also needed to allow easy access for

future maintenance. Being able to work

on the project during its initial stages

meant I was able to fulfil the client’s

requirements while also considering any

future maintenance processes.

MODERN METHODS OF

CONSTRUCTION – A SCALABLE

WAY FORWARD

Steve Richmond, Head of

Marketing and Technical

Building Solutions at

REHAU UK, explores why

MMC remains an

attractive building option

despite recent concerns.

With a growing need for

new buildings within

the UK, battling against

a shortage of space

and a skills shortage

within the construction sector, there is

high demand for new, scalable modern

methods of construction (MMC) such as

offsite construction.

The swift integration of panels and

modules within a controlled environment

is key to offsite construction’s

enduring appeal. Yet reports of subpar

components causing plumbing leaks

and insulation breakdowns has

dented developer and M&E contractor

confidence in MMC. But if these

concerns can be resolved, what MMC

offers – the rapid construction of highquality

properties – remains an attractive

proposition, especially considering

the escalating demand for buildings in

densely populated urban areas.

Projects in these areas are frequently

constrained by a lack of space. Building

upwards may present a possible

solution, but cramped site conditions

can compromise quality control. This is

further exacerbated by the continued

skills shortages in the construction

sector, with the UK Trade Skills Index

2023 highlighting the so-called ‘missing

million’ – the 937,000 new workers

by 2032 needed to meet growing

construction demand.

Intriguing possibilities

Considering these challenges, MMC

can offer intriguing possibilities for

developers and M&E contractors,

especially when considered alongside

current national housebuilding targets.

Though approximately 200,000 homes

24


are currently built every year in the UK,

a significant scaling up is required if

the sector is to meet the Government’s

target of 300,000 homes. Additionally,

growing demand from the commercial

sector, including new student

accommodations and hotels, must not

be overlooked.

OFFSITE

Addressing these concerns, REHAU

has unveiled its latest guide, Offsite

Trends in Building Services. Exploring

The swift integration of

panels and modules

within a controlled

environment is key to

offsite construction’s

enduring appeal.

how off-site construction techniques

apply to building services, and giving

examples developed by REHAU

MMC’s role in alleviating construction

pressures, the guide sheds light on

offsite construction’s potential and the

building services solutions developed

by REHAU to facilitate swifter project

completion. To that end, the guide also

seeks to enhance awareness among

consultants, developers, specifiers, and

M&E contractors of MMC technologies

and underscore the impact of these

innovative solutions on industry best

practice.

Technological trends

Yet MMC itself is not new. Offsite

construction is a rapidly evolving and

expanding sector encompassing various

installation approaches beyond the

offsite sub-assembly method most

popular in the UK. The guide looks

further afield and explores trends across

Europe, where offsite construction is

well-established, and where innovation

has continued apace with products and

practices becoming ever-more refined

over time.

Stay updated on advances

The practices and technologies available

demonstrate that offsite construction is

an expansive field. Collaborating with

third-party experts such as REHAU is

therefore essential if developers and

M&E contractors are to remain updated

on current MMC solutions and future

advancements.

For example, trends such as the

growing adoption of modular shafts

offer new avenues for delivering

mechanical services into prefabricated

units efficiently. Further possibilities

can be found in the risers used on

offsite projects to facilitate the delivery

of mechanical services to modules

and units. These components, which

have traditionally been made of copper

and steel, are now available in newer

materials such as fiber-reinforced PP-R,

which is available in larger riser sizes

that are easier to transport. Additionally,

these components can be welded and

tested offsite for greater assurances over

performance.

Moreover, the introduction of integrable,

customisable frames into offsite

bathroom builds has streamlined

future property maintenance. REHAU’s

acquisition of MEPA underscores its

commitment to providing comprehensive

MMC solutions in this area, including

easy-to-install sanitaryware.

Streamlining utility cupboards in MMC

projects also opens up more avenues

for efficiency. These spaces can house

modular plumbing components,

simplifying maintenance and reducing

plumbing fittings. REHAU’s Smart

Manifold exemplifies this, offering a

scalable, manifold-based plumbing

solution that significantly reduces the

number of required plumbing fittings.

In conclusion, the sector’s overall

goal remains the same – delivering

high-quality builds swiftly. MMC

emerges as an appealing way to

achieving this objective amidst current

industry pressures. Collaboration with

expert suppliers including REHAU is

instrumental for specifiers in ensuring

projects are completed seamlessly

and to a high quality. By embracing

innovation alongside trusted partners,

contractors and developers can make

this goal a reality.

KITCHENS, BATHROOMS

& WASHROOMS

BALANCING STYLE AND

PRACTICALITY

As one of the most visible elements of the kitchen, worktops need to work hard visually as

well as practically. Specifying materials that combine these two features is vital for the

heart of the home, argues Simon Boocock, Managing Director of CRL Europe.

Kitchen worktops are a critical element in any home.

Not only do they serve as the primary workspace for

cooking and baking, but they also set the visual tone for

the entire room. As a result, worktops need to strike a delicate

balance between functionality and style, and never more so

than in an open plan setting where shutting the door on the

kitchen is not an option.

The evolution of kitchen surfaces

Traditionally, kitchen worktops have been constructed

from various materials, each with its own advantages and

disadvantages. Wood or metal were popular, for example, but

these materials required significant maintenance and were

prone to damage. As technology advanced, so did the options

available for kitchen worktops, leading to the introduction of

more durable materials.

One of the most popular choices in recent years has been

white-veined marble effect surfaces, appreciated for the

classic, elegant look. However, trends are shifting once

again. As homeowners and designers seek more unique and

personalised designs, there’s a growing move toward bolder

colours and distinctive patterns in kitchen surface design.

Going bold with colour

The all-white kitchen, once synonymous with contemporary

design, is slowly fading. In its place, vibrant colours and

striking patterns are making a comeback. This shift towards

bolder aesthetics provides homeowners with an opportunity to

express their personality and creativity.

Deep blues, rich greens, and dramatic blacks are becoming

increasingly popular in kitchen design. These bold hues add

depth and contrast to the kitchen, creating a more vibrant

and engaging environment. For those who find all-white

kitchens sterile or bland, these colour choices offer a refreshing

alternative. Combining contrasting colours and materials

also continues as an effective zoning technique in open-plan

spaces, reflecting the multi-use nature of the kitchen.

For smaller kitchens deep, bold colours work particularly well

on furniture when teamed with a lighter colour worktop to lift

the look, while larger and light-filled rooms can more easily

accommodate a combination of these deep, dark tones on

work surfaces too.

Along with bold colours, unique patterns and textures are

gaining traction. Geometric designs, intricate abstract patterns

and natural stone textures add visual interest and depth to

kitchen worktops. These patterns not only break the monotony

but also serve as a conversation starter, giving the kitchen a

distinctive character.

Practical elements

When selecting a kitchen worktop, the choice of material

is crucial and needs to be based as much on its durability

and maintenance, as well as style. For this reason, quartz

and ceramic are increasingly popular materials for use in the

kitchen. Both are highly durable, resistant to stains, scratches,

and heat, making them an ideal choice. They are also nonporous,

which means they don’t require sealing and are

resistant to bacteria and mould.

This makes quartz and ceramic worktops a practical option

for families and those who frequently entertain. One of the key

advantages of such materials is their versatility. Available in a

variety of colours and patterns, providing flexibility in design,

this allows homeowners to experiment with different styles,

from minimalist to bold and vibrant.

When choosing the ideal kitchen worktop, it is important

to consider the consumer’s lifestyle, budget, and style

preferences. While trends are shifting toward bolder colours

and unique patterns, it’s essential to ensure that the chosen

material meets the practical demands of daily kitchen use.

DISAPPEARING KITCHENS

The more our kitchens become the central hub of the home, the more it ‘disappears’,

hence the rise in the hidden kitchen. But with appliances being an essential part of

the kitchen, is it really possible to hide these away? Ben Bryden, Sales and Marketing

Director at RAK Ceramics UK, takes a look at this growing trend.

In the modern household, the kitchen

has become more than just a place

to cook and eat. It’s the heart of

the home, a gathering place where

families come together, where we

entertain friends, and where the hustle

and bustle of daily life is played out. This

transformation of the kitchen into a multifunctional

space has driven a new trend

in kitchen design: the hidden kitchen.

As our kitchens become the central

hub of our homes, they also become

increasingly minimalist, with appliances

and clutter cleverly concealed to create a

seamless, integrated look and feel.

The allure of the hidden kitchen

The appeal of a hidden kitchen lies in

its simplicity and versatility. As openplan

living becomes more popular,

the kitchen is no longer a separate,

enclosed space. It often merges with

the living and dining areas, creating the

need for a cohesive design. A hidden

kitchen allows for a more unified look

where appliances, cooking utensils, and

even the kitchen sink can vanish from

sight when not in use.

This trend has grown in response to

the desire for a less cluttered, more

streamlined environment. Modern

homeowners are seeking a balance

between functionality and aesthetics,

aiming to maintain the practicality of a

kitchen without sacrificing style. This

has led to a surge in innovative design

concepts that conceal kitchen elements

while keeping them readily accessible.

Concealing appliances

One of the simplest ways to create a

hidden kitchen is to conceal appliances

behind cupboard doors or inside

custom cabinetry. However, designers

and installers are also pushing the

boundaries of what’s possible, using

more sophisticated techniques to hide

kitchen essentials. Retractable units are

a popular choice, allowing appliances

to slide or fold away into the cabinetry

when not in use.

This technique is particularly effective

for concealing dishwashers, ovens, and

even small appliances like toasters and

blenders. Panels and sliding doors can

be used to cover larger appliances,

creating a clean, unbroken surface that

blends seamlessly with the rest of the

kitchen.

Integrating hobs and worksurfaces

One of the most innovative solutions

in the hidden kitchen trend is the

integration of induction hobs into

the work surface. This technology,

exemplified by products such as

Cooking RAK, allows the cooktop to be

completely hidden when not in use. The

induction zones are embedded into the

worksurface, and the controls are often

28


touch-sensitive, enabling a completely

flat and uninterrupted surface. This

concept is particularly appealing for

minimalist kitchens, where clean lines

and uncluttered spaces are a priority.

With CookingRAK from RAK Ceramics,

for example, the kitchen worksurface

doubles seamlessly as a cooking area.

The induction hob is concealed in the

porcelain surface, taking the kitchen

from meal preparation to social space

effortlessly.

This hidden induction cooking system

creates a stylish impression in the

modern kitchen, combining the highperformance

of RAK Ceramics porcelain

slabs with an innovative induction

cooking system for professional results.

The surface itself – available in six

styles and a range of colour schemes

to suit any décor – is perfect for the

busy kitchen environment, because it is

resistant to heat, stains and scratches

and any spillages can be easily wiped

away.

Even extraction technology has evolved,

so that the open-plan kitchen doesn’t

need to have the visual obstruction

of a bulky hood. Instead, extraction

units can be incorporated into the hob,

removing odours and steam from the

room without anyone even knowing it’s

there.

Disguising the sink

The kitchen sink is another essential

feature that can disrupt the minimalist

aesthetic. To maintain a hidden kitchen,

designers are turning to solutions that

allow the sink to blend in with the

surrounding countertops. This can be

achieved with retractable sink covers

or inserts that transform the space

into additional counter space, making

the sink a multi-functional workstation

for chopping veg, draining as well as

washing up.

Balancing functionality and

aesthetics

While the hidden kitchen trend offers

a sleek and modern aesthetic, it’s

important to maintain functionality.

KITCHENS, BATHROOMS

& WASHROOMS

One of the most

innovative solutions in

the hidden kitchen

trend is the integration

of induction hobs into

the work surface. This

technology, exemplified

by products such as

Cooking RAK, allows

the cooktop to be

completely hidden

when not in use.

Designers and installers must strike a

balance between concealing appliances

and ensuring they remain easily

accessible. This often involves creative

use of storage solutions, clever layouts,

and advanced technology.

The hidden kitchen trend is likely

to continue evolving as technology

and design concepts advance. As

homeowners seek a harmonious and

clutter-free living space, designers and

installers will continue to find innovative

ways to make appliances ‘disappear’.

Ultimately, the hidden kitchen is about

creating a space that reflects the

changing dynamics of modern living,

where the kitchen serves as the central

hub yet remains flexible enough to

adapt to a variety of uses. It’s a trend

that speaks to our desire for simplicity

and sophistication, and one that is set

to define the future of kitchen design.

TRANSFORMING KITCHENS INTO

SELLING POINTS

In today’s competitive

housing market, kitchens

often serve as the

deciding factor in whether

a property sells quickly.

Sam Thomson, Contract

Designer at Waterline,

explores how minor

adjustments in contract

kitchens can transform a

property’s appeal from

‘meh’ to ‘must-have’.

When designing contract

kitchens, the goal is to create

spaces that are both functional

and visually appealing. These kitchens

are often assumed to be simple white

slab doors with basic T-bar handles,

but there are many ways to add depth,

warmth, and visual interest to make the

space inviting and stylish.

Incorporating texture into a kitchen

design can significantly impact its

visual appeal and tactile feel. Adding

textured surfaces, such as open shelving

or textured panels on end units, can

transform a plain white kitchen.

Lighting as a vital design element

Lighting is a critical but often overlooked

aspect of kitchen design. Consider

various solutions to add depth and

atmosphere to your kitchen. Beyond

traditional under-cabinet and ceiling

spotlights, think about lighting above

wall cupboards to brighten the space, or

pendant lights for task lighting. Effective

lighting can turn a dull kitchen into a

vibrant, welcoming area.

Design for the user

Contract kitchens are often designed

without direct input from house buyers,

so it’s crucial to consider the needs

of the end user. For example, a onebedroom

apartment may require a

simpler layout, while a three-bedroom

detached home might need more

storage for a young family. In assisted

living spaces, design with accessibility in

mind, focusing on easy-to-use taps and

adaptable storage solutions.

Play with visual interest

Creating visual interest can make a big

difference. Consider varying the heights

of wall and tall units, or incorporating

a unique focal point, like a decorative

hood, to draw the eye. This can create

a sense of dynamism and prevent the

kitchen from feeling flat or monotonous.

The architectural style of the property

is also essential in determining the right

design. A rural setting may call for a

farmhouse-style kitchen, while a luxury

apartment in London might benefit from

a sleek, modern design. Understanding

the property’s context and architecture

ensures that the kitchen design

complements the broader environment.

Branded appliances

Including branded appliances in contract

kitchens can significantly boost their

appeal. Reputable brands are associated

with quality and reliability, offering

a sense of luxury and consistency.

Matching appliances in terms of colour

and design also creates a cohesive look.

Modern tap technology can be a key

selling point. Hot water taps offer instant

boiling water, while filter taps provide

clean, filtered water, reducing the

need for bottled water. These features

add convenience and sustainability,

enhancing functionality and appeal.

Maximise space and flow

The layout of a kitchen greatly affects its

usability and appeal. An open layout can

create a sense of space, while strategic

placement of the work triangle ensures

efficiency. Reconfiguring cabinets,

adding pull-out shelves or installing

a pantry can improve storage and

organisation.

Small details like hidden storage

solutions, task lighting and decorative

hardware can significantly impact a

kitchen’s overall appeal. Integrated

rubbish bins, pull-out spice racks, and

stylish handles can add functionality

and aesthetic value. Task lighting under

cabinets enhances workspace visibility,

creating a safer, more functional kitchen.

In a competitive housing market, every

detail counts. By focusing on texture,

lighting, layout, branded appliances,

and thoughtful design, contract kitchens

can be transformed from ordinary to

extraordinary. These enhancements not

only improve the property’s desirability

but also create a space where buyers

can envision themselves living,

cooking, and entertaining. Waterline,

as a one-stop shop for kitchen design

specification, has an in-house design

team, excellent customer service and

prompt distribution including next-day

deliveries on remedials.

Go handleless

Handleless furniture creates a cleaner,

more streamlined look, adding a touch

of sophistication. Handleless options

can elevate the overall aesthetic, making

the space feel contemporary and

uncluttered.

EXTENDED WARRANTIES AND NEW PRODUCTS FROM DELABIE

DELABIE has begun 2024 with a number of new product

launches and an extension of its warranties, as the fourthgeneration

family-owned business looks to the future.

The manufacturer of taps and sanitaryware for public

places has extended its warranty from 10 to 30 years on all

its products, as well as increasing the lifespan of its spare

parts up to 50 years for technical products. This decision,

the company says, is based on concrete evidence that

DELABIE taps have an average 25-year lifespan before

needing replacement. It also says these replacements are

typically due to refurbishment of the premises, rather than

product failures.

DELABIE has also introduced a number of new products,

such as the deck-mounted Tempomatic 5 electronic basin

mixer and tap, which offers a hygienic solution for users

in public spaces. Tempomatic 5 is positioned to make it

more cost effective for users to switch to 100% touch-free

electronic controls, removing any risk of spreading germs

by hand. The flow starts and stops automatically without

manual contact and the pipework is flushed daily, every 24

hours after the last use to prevent bacterial development.

There is a new range of 4-in-1 mirror cabinets, combining

functionality and aesthetics and integrating a mirror, soap

dispenser, tap and air pulse hand dryer all in one – and all

sensor activated for improved hygiene. The cabinet is also

available in a 3-in-1 version without the water function, for

users who wish to leave the tap visible, or for renovations

where a tap is already present.

The cabinet has a matte black finish and subtle lighting,

and is fitted with a lock and standard DELABIE key to

provide effective protection against vandalism. Designed

to be easy to install, the cabinet has one single electrical

supply for all the elements.

For users with additional accessibility needs, DELABIE

has also extended its BASIC range with a new shower seat.

The BASIC+ shower seat has a solid, non-slip polypropylene

seat to allow users to enjoy a comfortable shower in

confidence. The structure of the shower seat is made of

aluminium, making it robust and durable.

The BASIC+ seat lifts up to take up as little space as

possible when not in use, requiring just 85mm of space. The

seat has a 30-year warranty, is CE marked and tested to

over 200kg.

DELABIE has also introduced a new range of stainless

steel sanitaryware with a matte black Teflon finish, offering

a retro-chic style with an industrial edge. These new

washbasins, WCs and urinals are made from 304 stainless

steel, making them durable and light, while coated with

a Teflon finish that will remain intact for a long time. As a

non-stick surface, scale will struggle to stick to the service,

making it easy to keep clean.

The range features 15 products: inset and countertop

washbasins; wall-mounted washbasins; wall-hung or freestanding

WC pans; WC pans for disabled toilets; WCs

without cisterns; urinals and urinal dividers.

INTEREST IN COMPACT LAMINATE WORKSURFACES ON THE RISE

A combination of socio-economic factors including recent

health and safety concerns around engineered stone

kitchen worktops has seen interest in compact laminate

surge, according to insight from Elliott Fairlie, Product Lead

at Bushboard.

The convenience of being able to install compact

laminate on site, and the resulting benefits this brings, is

driving growing interest in the product across the breadth of

the supply chain.

The growing influence of the cost-conscious consumer,

demand for accessible luxury in kitchen design and the

increasing awareness of the risks posed by silica when

working with engineered stone, have seen compact

laminate worksurfaces emerge as a safe, versatile option for

specifiers in a challenging market.

Due in part to their cost-effective nature, compact

laminate worksurfaces are a viable alternative to traditional

stone, quartz or marble. Manufactured by compressing

layers of kraft paper soaked in resin under high pressure

and heat, compact laminate worksurfaces are also surging

in popularity given their ability to be cut and installed onsite.

With consumers understandably reluctant to spend big

on major kitchen upgrades, compact laminate offers a

premium look comparable to natural alternatives such as

stone or quartz, but at a more affordable price point, while

avoiding any major health and safety risks associated with

the manufacturing process.

The latest slimline worksurfaces have been developed

with flexibility, functionality and visual impact in mind. As the

trend for minimalism and open-plan living spaces remain

popular, thin yet extremely durable compact laminate

worksurfaces create the ‘barely-there’ effect desired by

many.

Bushboard has released its updated Zenith range of

compact laminate kitchen worksurfaces, featuring six new

décor options. Consisting of 20 designs with an ultra-slim

profile, it is now possible to replicate the texture of real

stone and marble counterparts while ensuring the highperformance

associated with these natural materials.

The waterproof and non-porous nature of compact

laminate worksurfaces, like Zenith, also allows for the

installation of undermount sinks to create curved edges and

bespoke areas. The inclusion of antibacterial protection,

which is added to the compact laminate in the form of resin

during the manufacturing process, slows down bacterial

growth by up to 99.9% of the surface’s lifetime.

IT’S ALL IN THE DETAIL: ROCA’S NEW TURA COLLECTION

Roca has collaborated with designer Andreu Carulla

to create its Tura bathroom collection. Carulla drew

inspiration from the architectural designs of his hometown

of Barcelona to create a range with soft finishes and natural

textures that capture the beauty of the Mediterranean.

The range includes washbasins, furniture, small-space

solutions, baths, WCs, bidets and accessories.

The washbasins have strong lines with soft corners and

subtle curves, with a hidden drain seamlessly integrated

into the design for a smooth, uninterrupted bowl.

The shape of the bath is inspired by an architectural

cantilever system, creating the illusion that it is floating

in space. This effect is amplified by the option of an LED

light around the base. The bath is made from Roca’s

composite Stonex, which creates a bath that is spacious

and light, with thin walls and a slim ridge around the edge

to accommodate a wooden bath tray. Stonex is also warm

to the touch, anti-slip and easy to keep clean.

The Tura WCs and bidets come in wall-hung,

floorstanding and close-coupled options. All ceramics

are available with Roca’s antimicrobial Supraglaze finish,

making it difficult for dirt and limescale to stick to the

surface.

ADD MORE THAN FUNCTIONALITY

WITH A HEATED TOWEL RAIL

As specifiers strive to create homes that reflect modern life, the role of heated towel

rails has transcended mere functionality. Here Spencer Clarke, Specification

Manager at The Radiator Company delves into the latest trends and explores the

vast array of options now available.

When it comes to

the housebuilding

market, architects

and specifiers face

diverse challenges

when designing bathrooms for residential

properties. From affordable housing

with compact layouts to luxury homes

with multiple bathrooms, the design

requirements vary significantly.

Whatever the property type, every

bathroom needs to be the right

temperature and provide a comfortable

environment in which all users can spend

as long, or as little time as they wish.

In designing the layout of a bathroom,

the placement of essential elements

such as the shower, bath and sink takes

precedence. Yet the consideration of

the heating supply often comes as an

afterthought, resulting in limited options

for integrating heated towel rails and

radiators.

Fortunately, reputable manufacturers

offer an extensive range of heating

products capable of accommodating

the most constrained layout – although

early consideration is always preferable.

For small spaces, the towel rail may

even be sufficiently powerful to heat the

bathroom space and achieve the desired

BTU output.

The Future Homes Standard effect

The climate emergency, energy costs

and homeowners’ evolving attitude

towards sustainability means the

demand for more energy-efficient

and sustainable heating solutions in

residential projects is on the rise.

Reinforced by the UK Government’s

introduction of the Future Homes

Standard, which will require new homes

built from 2025 to produce 75-80% less

carbon emissions through the installation

of low-carbon heating sources like an air

source heat pump (ASHP), consideration

needs to be given to heating

connections early on in the design

process. While a seemingly small aspect

of the overall development, heated

towel rails can contribute to reducing

energy consumption. Modern models

are equipped with features such as

thermostatic controls and programmable

timers, allowing for precise temperature

regulation and efficient usage.

Where a heated towel rail can be

connected to both a central heating

system and an electric power source,

dual-fuel towel rails offer flexibility and

efficiency. So, where a dual-fuel heated

towel rail is specified for a heating

system that runs off a heat pump it can

be heated by an electrical element in

the summer on a timer, and by the heat

pump in the colder months.

Electric-only towel rails provide a

standalone heating option, making them

36


ideal for supplementing existing systems,

and optimising energy usage for the

homeowner because they’re switched

on only when necessary.

Minimise environmental impact

Another way to step towards

reducing environmental impact is the

consideration of the material used.

Aluminium heated towel rails are the

ideal specification. A material that is

fully recyclable at the end of its useful

life, aluminium is also a superconductor,

which means it can rapidly respond to

thermostatic changes to heat up quickly

and cool down with speed. As such,

these radiators require less water to

function and, as they are highly efficient

at responding to user temperature

preferences, less demand is placed on

the central boiler.

Be smart with the specification

With some housebuilders now tailoring

formats to quite specific persona profiles,

the integration of digital and

While a seemingly small aspect of the overall

development, heated towel rails can contribute

to reducing energy consumption.

smart functionality in heated towel

rails will appeal to the more techsavvy

homeowner, adding a layer of

convenience and sophistication to

bathroom design. Wi-Fi connectivity,

control capabilities and voice activation

features offer users unprecedented

control over their heating systems,

enhancing the overall bathroom

experience.

A stylish upgrade

Heated towel rails are not just functional

but also provide opportunities to add

design interest to bathrooms or, with the

multitude of styles and colour finishes,

as part of a bathroom package upgrade.

Where a plumbed chrome or white

standard ladder towel rail has traditionally

been the go-to solution, more designled

options can create space and make

a design statement. By specifying a

towel rail finished in an alternative shade

it elevates an ordinary product into

something more eye-catching. What

better way to create a look that will

impress potential homebuyers looking to

finish their bathroom scheme with style

and also benefit housebuilders when it

comes to sales opportunities.

Of course, specifiers are no stranger

to the allure of black, with matt black

remaining a favourite to evoke luxury

and sophistication. When paired with

complementary black bathroom fittings,

this bold finish is effective in creating

a cohesive space. Plus, it provides

elegant contrast for colourful bathrooms,

which are here to stay with pastel pinks,

gemstone greens and dramatic blues

all in demand, should the homeowner

choose that route.

KITCHENS, BATHROOMS

& WASHROOMS

Additionally, a wide range of modern

and traditional style options allows for

seamless integration with various design

schemes. The Radiator Company’s

side-loading Echo, for example, provides

a way to upgrade the common ladder

towel rail with an impressive design

where users can simply slide the towel

onto the rail. For those looking to

emulate period features, towel rails such

as the Linton can enrich such design

themes. This product combines white

powder-coated cast iron sections and

chromed pipework to reflect the style of

the 1920s.

Heated towel rails have evolved into

indispensable elements of modern

bathroom design, offering a blend of

functionality, comfort, and style for

newbuilds from compact apartments

to luxurious residences. As architects

and specifiers continue to push the

boundaries of creativity, the future

of bathroom design is undoubtedly

bright with heated towel rail innovation

continuing to hot up.

GLASS & GLAZING

HOWELLS SUPPLIES ROOFLIGHT FOR

LONDON’S OLDEST BOOKSHOP

London’s oldest bookshop

gets a brand new rooflight

as part of a challenging

refurbishment project

carried out by Chrisalis

Refurb and Howells

Patent Glazing.

Hatchards is a British institution.

Occupying 187 Piccadilly, it is

the oldest bookshop in London.

Established in 1797 by publisher and

anti-slavery campaigner, John Hatchard,

it boasts three Royal Warrants.

The booksellers, now owned by

Waterstones, exclaims that the ‘essence

of 187 Piccadilly remains the same and

is unchangeable’. This presented quite

a challenge for contractor Chrisalis

Refurb, which was tasked with supplying

and installing external scaffold access

to the front elevation up to roof level,

incorporating a temporary roof, giving

access to remove the existing rooflight,

making good areas of the existing

opening, then supplying and installing a

new bespoke rooflight. For the glazing

solution, the contractor sought the

expertise of Howells Patent Glazing.

Being a listed building, the old rooflight

at 187 Piccadilly had to be replaced like

for like. Originally the rooflight would

have been single glazed with lead, but

over the years it has been updated and

Howells was tasked with replacing the

Georgian wired cast glass, which itself

had been in-situ for between 20 and 30

years.

Survey and specification

The rooflight sits above an office space

with a suspended ceiling, which also

had to be factored into the specification.

Draughtsman Warren Lowe attended

site for an initial survey, which proved

particularly challenging due to the

position of the rooflight, the roof

structure and details.

Warren explains: “The Georgian wired

cast glass is not classed as a safety

glass nowadays so had to be replaced,

plus it was starting to slip and leak. We

recommended a replica polycarbonate to

meet the requirement for a single glazed

option, and because it is lightweight

so wouldn’t add extra load to the steel

support frame. Not being translucent,

it is also aesthetically more pleasing

given the view of the suspended ceiling

beneath.”

For the structure of the rooflight

Howells selected its HG3 bar. While the

internal stalk would be covered by the

suspended ceiling below, the external

wing bar is visible and is a good match

for the original, as is the bar’s uncoated

mill finish which will dull down overtime.

Once the scaffold had been erected,

Howells carried out a full survey and

produced drawings for client approval

and, later, manufacturing. These

drawings were also used by the client to

gain approval from Building Control.

Overcoming the challenging location

Piccadilly is an extremely busy

thoroughfare in central London. This,

and the rooflight being five storeys up,

meant the removal and installation of

the rooflight had to be meticulously

managed.

A pre-start meeting was held onsite

with Chrisalis Refurb, the scaffold

company and Howells to agree the lifts

of the scaffolding; where the scaffold

loading area and hoist would be situated

to enable the existing rooflight to be

removed, broken into sections and

then disposed, and the delivery and

installation of the new rooflight.

The removal and delivery were carried

out at weekends to minimise disruption,

while the new aluminium rooflight was

delivered in sections and hoisted up

to roof level ready for installation. The

existing steel support frame for the

rooflight was made good prior to the

installation of the new aluminium replica

rooflight by Howells’ fitting team. The

entire process was carried out inside a

scaffold tent to prevent rain ingress and

stop falling debris.

A spokesperson from Chrisalis Refurb

says: “We found Howells to be very

professional and reliable from the initial

planning stages with Walter Howells

through to getting drawings approved

with Warren Lowe.”

RE-DEFINING HIGH-RISE LIVING

Winter Gardens are an ideal way of offering high-rise residents access to a

contemporary, all-weather outdoor space. They also require a specific set of

building materials that meet the required fire safety regulations. It’s for this reason

that Pyroguard Balustrades was chosen for London’s Deanston Wharf development.

Deanston Wharf is a vibrant new

development located on the curve

of the River Thames, adjacent

to the flagship River Wharf. Featuring

four separate building plots, ranging

from nine to 17 storeys, the site will

bring more than 760 new homes to the

local area, comprising a mixture of one,

two and three-bedroom apartments; in

addition to commercial space, leisure

facilities and a luxury sky lounge.

Developed by Oxley Holdings

and Ballymore Construction, Elite

Architectural Systems was brought onto

the project to design, supply and install a

series of glazed winter gardens on select

apartments. Winter gardens are an

architectural trend that has significantly

grown in popularity over recent years,

formed of an enclosed, glazed and

ventilated balcony. As well as offering

a modern and striking external feature,

winter gardens provide residents with

access to a garden space that they can

enjoy year-round, helping to bring the

outside in, and vice versa.

They can also offer a safer alternative

to balconies on high-rise residential

buildings, and are occasionally

recommended by London planning

guidelines due to the increased

wind speed and noise that can be

experienced.

On the Deanston Wharf development,

the winter gardens featured a glazed

balcony with a folding partition, enabling

residents to open up the space in the

warm, sunnier months and then close it

up during winter.

Noel Gilmartin, Operations Manager

at Elite Architectural Systems, says:

“Due to the high-rise setting, fire safety

Manufactured to Reaction to Fire

classification A2-s1, d0 (according to BS

EN13501), Pyroguard Balustrades also

offers excellent light transmission and is

certified to 1B1 impact resistance rating

(according to EN12600).

Noel continues: “Working with Pyroguard

on the Deanston Wharf project was a

great success, especially with regards to

the technical support they offered. Given

the stringent fire safety regulations and

the emphasis on traceability, we had to

supply our client with comprehensive

datasheets, test evidence and

certifications. Thanks to the support

from Pyroguard and Q-Railing, we were

able to deliver all of this to the client,

smoothly and efficiently.”

REYNAERS LAUNCHES DIGITAL DOCUMENT PORTAL AND HARDWARE CONFIGURATOR

Reynaers Aluminium has launched two online tools to

provide specifiers, fabricators and installers with real-time

product and technical information, as well as its hardware

selection and comparator. Both software solutions are now

accessible through Reynaers’ Customer Portal.

The Docu Portal brings together the equivalent of 20,000

catalogue pages and is the latest in a number of online tools

from Reynaers designed to make it easier to design, order,

fabricate and install the latest window, door and curtain

walling solutions.

Through Docu Portal, Reynaers’ customers will be able

to quickly and easily access in-depth, technical guidance

for the fabrication and installation of its systems. Through

a personalised login, customers can also save favourites.

They will then receive specific notifications of any relevant

updates.

A Hardware Configurator has been created to offer

rapid analysis of the most suitable hardware for a project.

Drawing on all available Reynaers’ products and compatible

components, the hardware configurator provides an

overview that allows products to be easily compared to

identify the best solution.

Martin Boland, Technical Support Manager at Reynaers

Aluminium UK, said: “Docu Portal was developed

specifically to address the challenge in accessing

and searching through the vast amount of information

available. As well as easy navigation of over 20,000

documents, the customer can also compare and select

a number of hardware solutions. Coming soon will be the

ability to set up tailored mini manuals to access offline.

“Ultimately we want to make life as easy as possible for

our customers and, by offering an up-to-date online solution

to navigate our vast product range and technical support

documentation, we aim to add real value to the support and

products we provide.”

Reynaers has introduced digital innovations to help offer

a seamless customer experience. These include a customer

portal that links to a download centre containing technical

information and that allows deliveries to be tracked, while

ReynaPro offers accurate pricing, generates order lists,

production schedules, provides assembly instructions – and

links to an electronic ordering system.

Reynaers is also in the process of adding ‘digital

passports’ to all systems that will provide electronic data

associated with each individual product.

ELEVATING HOME ENTERTAINING WITH SEAMLESS SPACES

Homeowners are increasingly investing in upgrades

within the home that make the at-home wining and dining

experience exceptional. From a space dedicated to wine

storage, to an all-weather outdoor seating area, the perfect

internal and external home upgrades are made possible

with CRL.

Internal upgrades may include the inclusion of bottle

storage, the latest cooking technology and kitchen islands

that double as a bar or dining area, while externally there

are changes afoot too.

The glass, glazing and stone expertise of CRL was

recently called upon by Glass and Mirror Technology,

tasked with creating inside-outside socialising spaces,

including a dedicated wine storage area indoors and a

comfortable outdoor living area.

Specifying CRL fittings for a sleek and seamless look, a

showpiece wine storage unit was created. Using a 10mm

U channel and 10mm glass, coupled with the Geneva

hinge in Matt Black and a Ladder pull-door handle, the unit

was simple to install and has an understated elegance.

Inside the wine storage unit, the back wall is clad in Umbra

from CRL, a hard-wearing, stone-inspired surface that

creates an air of luxury.

For the times when enjoying a glass of two of wine

outdoors is on the menu, CRL solutions were also used to

create an outdoor living space, complete with kitchen and

seating area. CRL SpigLite Pro provides an effective, easyto-fit

windbreak solution, that enables water to pass under

the glass.

Without a channel, there is a greater percentage of

glass visible to maximise the view of the garden beyond

the seating area, while the individual spigots allow for free

flow water drainage making this system perfect for wet

areas. Mechanised by a patented screw-clamp adjustment

device, each individual panel of glass in the system can

be horizontally adjusted once in position, for accurate

installation and flawless finish.

As the trend leans towards luxurious at-home socialising,

CRL’s expertise ensures every aspect, from dedicated wine

storage units to all-weather outdoor seating areas, exceeds

expectations.

SPECIAL FEATURE

CHOOSING THE RIGHT MEMBRANE

FOR YOUR PROJECT

Hidden from view, pitched roof underlays usually warrant little attention from

building users. But the latest generation of membranes can play a significant role in

future-proofing buildings and protecting occupants from unhealthy indoor climates.

Sue Menmuir, Technical Advisor at A.Proctor Group, explains why specifiers should

give new underlay solutions careful consideration.

Pitched roof underlays sit at

a crucial interface between

the external climate and a

building’s internal climate.

They are a secondary layer

of weather protection below the finished

roof covering, and they also influence

how moisture vapour is managed within,

and released from, the building.

Underlay products are usually described

using the catch-all term ‘breather

membranes’. This generic description

doesn’t reflect the distinction between

high-resistance (HR) and low-resistance

(LR) membranes. Furthermore, LR

membranes can be airtight or air

permeable, so the generic term also

doesn’t capture the role underlays can

play in making sure roof spaces are

properly ventilated.

Water resistance of

pitched roof underlays

During the installation of a roofing

system, there is an inevitable period of

time where the underlay will be in place

without a roof covering to protect it. The

underlay might, therefore, have to bear

the brunt of any inclement weather.

The NFRC’s Technical Bulletin TB06

describes how membranes should

perform in terms of water resistance. It

says an underlay with “a water hold out

over 1m when tested to BS EN 20811

will be adequate”.

Newly installed roof systems can be

expected to remain in place for decades.

In the face of a changing climate, with

an increased frequency and intensity of

extreme weather, it’s essential to factor in

resilience to a pitched roof specification.

Roof systems generally – and

membranes as a specific part of

those systems – need to be capable

of withstanding more severe levels of

rainfall. An underlay’s ability to perform

with a 1m head of water is a minimum

level of performance to look for during

product selection.

Meeting the demands

of modern living

Water hold out on the external side must

not impact on vapour permeability – or

air and vapour permeability, if both are

offered – from the internal side. People

generate high moisture loads within

buildings, from cooking, bathing and

drying clothes indoors. Now that more

people have adopted hybrid working and

spend more time at home, excessive

levels of moisture vapour in the air are

increasingly common.

As buildings have become more airtight,

inadequate ventilation provision struggles

to deal with these high moisture loads.

Homes no longer feature open fireplaces

and large chimneys, for example. Warm

air rising into roof spaces therefore

carries a lot of this moisture vapour with

it.

As a first line of defence, top floor

ceilings should be well sealed to reduce

the quantity of moisture vapour entering

the roof space. However, even if a

vapour control layer (VCL) is installed well

initially, its continuity can be affected if

modifications are made later, like adding

downlighters.

Dealing with complex specification

Roof spaces should be ventilated to

remove any moisture vapour entering

the loft. Even the simplest form of roof

can feature a lot of complexity when it

44


SPECIAL FEATURE

comes to providing the correct level of

ventilation. The need for eaves ventilation

alone, or a combination of eaves and

ridge ventilation working together,

depends on several variables.

A traditional HR membrane, like bitumen

felt, doesn’t allow the passage of vapour

or air. The width of the building – and

therefore the distance across the roof

space – then becomes a consideration.

unobstructed, dual-pitch roof that usually

illustrates ventilation guidance.

Restrictions at eaves level (like increased

insulation thicknesses), changes in roof

slope (ie, valleys and hips), and changes

in construction details (eg, a junction

between a pitched roof and a flat roof) all

make clear roof spaces more difficult to

achieve.

Newly installed roof systems can be expected to

remain in place for decades. In the face of a

changing climate, with an increased frequency

and intensity of extreme weather, it’s essential to

factor in resilience to a pitched roof

specification.

The pitch of the roof can also affect

whether adequate airflow is achieved.

A more modern LR membrane might

be airtight, allowing vapour diffusion,

but without the additional benefit of air

passing through to enhance moisture

removal. That prompts the question

of whether the ceiling is well sealed or

not. Whether eaves ventilation, ridge

ventilation, or a combination of both

is required, there is no single solution

in terms of the size of ventilation

openings that must be installed. And not

every roof space matches the simple,

Any complicated detailing – such as

dormers, roof windows, compartment

walls, fire barriers or changes in pitch –

create separate voids in the roof slope

and require more ventilation openings.

They change how air flows within a roof

space, reducing air flow and meaning

moisture removal is not consistent

across the whole roof.

An LR membrane for the future

With all of these challenges in mind,

A.Proctor Group’s new pitched roof

underlay, Proctor Air, is the perfect

solution for roofs of all types. As an

air permeable LR underlay, no VCL is

required in the ceiling and no additional

ventilation measures are required in the

cold roof space. The membrane permits

the passage of both air and moisture

vapour through the roof construction, to

the outside.

Proctor Air reduces the risk of issues

occurring in roof spaces due to poorly

installed VCLs or ventilation, since

neither is needed. In fact, Proctor Air

provides a more uniform flow of air than

normal vents, helping to prevent ‘dead’

areas of poor ventilation in complex

roofs.

Proctor Air’s water resistance has also

been tested and meets the threshold of

over 1m of water holdout recommended

in the NFRC’s Technical Bulletin TB06.

Where periods of severe inclement

weather, or prolonged exposure,

are expected during installation, BS

5534 and BBA Bulletin 2 advise that

temporary protection be considered.

This is especially important in retrofit

projects, where occupants are likely to

remain in residence or there are sensitive

internal finishes.

By choosing and installing Proctor Air,

specifiers, contractors and building

owners/managers can enjoy the

confidence that comes from a highperformance

product doing its job

without intervention. All of this is backed

by a 15-year warranty, offering peace

of mind even in the face of an uncertain

future climate.

DRAINAGE & WATER

MANAGEMENT

FOCUS ON WATER SAVINGS

Easy to implement water management technologies can enhance efficiency, save

costs and bolster hygiene in modern commercial and large residential buildings,

says Richard Braid, Managing Director of Cistermiser.

Managing water effectively is essential in both

commercial and residential settings and with advances

in technology, water management is becoming easier,

smarter and more efficient. For specifiers, facilities managers

and housebuilders, effective water management can lead to

a conservation of resources, significant cost savings and the

mitigation of health risks.

Utility costs are on the rise and while energy, lighting and

heating are typically scrutinised, water is often overlooked.

Yet small changes can make a big difference. Hygiene is also

important to consider. The presence of biofilms in the water

pipe networks can increase bacterial levels, reduce dissolved

oxygen and cause taste and odour changes. In flushing

systems, biofilm and scale can build up unnoticed, eventually

leading to water leaks.

Sensors

Focusing on toilets, taps and showers is a good place to start

in any building. Infrared motion sensors make for intelligent

leak prevention systems by automatically opening the water

outlets, allowing water to flow only when the washroom is

occupied and closing it off when no motion is detected.

Cistermiser’s Sensazone intelligent leak protection solution, for

instance, fully protects washrooms against the risks associated

with water damage or flooding from faulty water outlets by

closing off the water when no motion is detected, reducing

utility bills and water wastage.

Infrared taps are another water conservation solution as they

only run while hands are moving beneath the tap so you can

significantly minimise on water waste. Infrared sensor taps like

For specifiers, facilities managers

and housebuilders, effective water

management can lead to significant

cost savings.

Cistermiser’s Vecta+ range go one step further by cuttingoff

after 60 seconds, reducing the risk of water wastage and

flooding.

Flushing

Direct flush systems are also important when it comes to water

management. Cisterns are often installed out of familiarity, but

they can pose a risk to hygiene if they remain idle for extended

durations: stagnant, room temperature water in a cistern

can create the ideal breeding ground for harmful bacteria like

Legionella. One flush may also not be enough to clean the

bowl.

Direct flush systems use supply pressure for an immediate

flush, avoiding the hygiene risks associated with standing

water in cisterns and the mechanisms enable an effective

single and dual flush. Some will perform automatic hygiene

flushes to keep the bowls clean and replace any water

in the pan that has evaporated. Direct flush systems, like

Cistermiser’s Easyflush Direct, cater to both hygiene concerns

and water conservation demands. There’s no need for a

cistern as it takes water directly from the mains supply,

meaning a second flush can be activated immediately. It also

has a hygiene flush that can be activated to keep the pan

clean.

Leaks

One critical aspect of water conservation is the early detection

and eradication of leaks. According to Waterwise, between

five and eight per cent of UK toilets are leaking, wasting as

much as 400 million litres of clean, fresh water every day. The

problem often lies with the type of valve predominantly used

in dual flush toilets – but the issue is completely preventable.

Cistermiser has developed solutions like the EasyflushEVO

siphonic flushing valve, designed to prevent leaks by

eliminating the common failure points found in traditional

systems. Each unit can save up to 146,000 litres of water per

year. Cistermiser’s Easyflush Direct is another option. It needs

no cistern or inlet valves and comes with flow regulators to

guarantee flush volumes and maximise water savings.

Effective water management is not just for conservation - it is

also a financial and health safeguard. With the pressing issues

of escalating utility costs and global water scarcity, innovative

water management strategies are no longer optional – they’re

imperative.

TACKLING TODAY’S CONSTRUCTION

CHALLENGES

As part of the launch of Polypipe Building Services’ new MecFlow Supply System

range, an expert panel discussed the skills shortage and other issues facing today’s

construction industry. Specify & Build reports.

At a recent event held in

London, Polypipe Building

Services gathered together

many representatives of the

building services industry

to get an exclusive first look at its latest

new products. Attendees were also

able to watch a panel discussion where

industry experts explored some of the

key challenges facing construction

today.

The panel was hosted by Phil Henry,

Built Environment Development Director

at Genuit Group, with representatives

from some of the industry’s most wellknown

construction companies and

architects, including:

• Scott Tacchi, Head of MMC at Sir

Robert McAlpine

• Dale Sinclair, Head of Digital

Innovation at WSP

• Colin Ainger, Partner at HTA Design

• Ian Crickmore, Technical Director at

Polypipe Building Services.

The ever-present skills gap was the first

issue discussed by the panel. It’s wellknown

that the construction industry

needs 225,000 new workers by 2027

to keep up with demand, and yet the

lack of available labour continues to be

an issue. This is despite construction

accounting for around 7% of UK GDP.

One of the main problems, the panel

said, is that just 5% of school leavers

see construction as an attractive career

option. When asked what more needed

to be done to help address the issue,

Scott said the industry as a whole

needed to consider how we’re selling the

industry to the next generation.

“Do we sell the current industry, or do

we sell what I believe is the future of the

industry, through offsite construction,

with higher productivity, improved quality,

less defects, better training and vastly

improved health and safety? Is what

we’re selling attractive to people?” he

asked.

Dale agreed that offsite manufacturing

could help make construction more

appealing. He said: “I genuinely believe

that by the end of the decade, we will

do things very differently to what we do

today. We’re already seeing the shift, but

this is a huge industry so it’s not going to

happen overnight.

“And if we are going to introduce more

offsite factories in the UK, we need to

look at where we put them, and they can

offer a huge levelling up opportunity to

society in general.”

Colin agreed that architects have a

strong role to play. “Architects have a

real responsibility to help break down

the barriers and get the message out

to young people that architecture and

design is an option for them. We’re

also seeing a huge digitalisation of

the industry in terms of software and

different AI tools, and that’s something

that young people can really contribute

to.”

Introducing MMC

The panel then moved more firmly

into the world of modern methods of

construction (MMC), and how it can

help to decarbonise the industry and,

again, tackle low productivity in the

construction sector. Colin said HTA

Design has been interested in the

opportunities offsite manufacturing and

for decades, and in fully volumetric

modular housing in particular for the last

15 years.

He said: “We’ve developed a real

specialism in that field and have actually

delivered around 15 completed fully

volumetric buildings to date, including a

50-storey tower in Croydon. We see very

significant benefits in terms of waste, as

well as huge reductions in construction

traffic to site.” Colin continued that

MMC also offers “fantastically safe,

warm, dry working environments for

the people who work in the factories,

and the carbon savings are very

significant. We’ve seen a fairly consistent

40% reduction in carbon within steel

volumetric buildings compared to the

traditional concrete equivalent.”

The panel agreed that most sectors in

construction are starting to consider

MMC as a way to reduce the amount

of carbon in their buildings, and that

clients are looking to architects, builders

and designers as the experts who can

help them achieve that. The important

requirement that will help push MMC

forward and really enable it to develop

is increased standardisation, the panel

said, creating standardised frameworks

that can make it easier to complete

these MMCs offsite, especially for

large-scale buildings such as hospitals,

schools and prisons, but while still

allowing architects and designers to

keep the overall look of the building

interesting so buildings don’t all end up

looking the same. The goal, they noted,

is to make it easier to standardise the

important parts of a building so that they

can be easily loaded onto lorries and

shipped to site.

COMBATTING INSUFFICIENT

WATER PRESSURES

As the population within UK

cities continues to rise,

meeting the growing

demand for water supply

is becoming increasingly

difficult. Jason Cox, Sales

Director – Building Services

at Wilo UK, explains why

cold water pressure

boosters will become

more important in retrofit

and newbuild

developments.

Once required only for high-rise

buildings, cold water pressure

boosters are now crucial for

several different property types across

the country. While Ofwat stipulates that

water pressures should always be at a

minimum of 0.7 bar, properties dropping

below this level is becoming an all-too

common occurrence. The reality is that

certain outlets in buildings even just twoor

three-storeys high won’t meet this

minimum pressure, depending on their

geographical position.

A solution is needed sooner rather than

later, and specifiers are at the heart of

this challenge. Cold water boosters

could prove to be just that, delivering

constant pressure at every extraction

point throughout a building and leaving

trickling taps a thing of the past.

with an estimated payback period, so

customers know when to expect these

savings before they invest in cold water

booster sets.

Making the most of a supplier’s expertise

when selecting the correct product is just

as important to the long-term success

of a pressure-boosting system. Aside

from installing the relevant upgrades,

Wilo supports specifiers who may require

assistance with selection, supply and

commissioning of pump equipment on

their own projects.

Opting for smart products

When it comes to replacing existing

boosters, selecting a smaller motor

that can supply the same demand of

water pressure is vital to improving

energy efficiency. Replacing equipment

with IE1, 2, 3 and 4 motors with Wilo

booster sets that feature the latest IE5

motors can also provide invaluable

carbon and energy savings. The Wilo

SiBoost 2.0 Smart Helix VE, for example,

is the manufacturer’s latest offering

for commercial applications. A heavyduty

yet efficient system, the booster is

designed to ensure a maximum degree

of control performance.

Progress in practice

A popular student residence in the

south-west of England put progress

into practice by initially reaching out to

Wilo for an on-site energy report. It was

discovered that efficient, straightforward

improvements to the property’s booster

set could save over £6,000 and more

than 46,000kWh a year. Wilo also

determined that upgrading to a SiBoost

Smart Helix VE would pay for itself in

just over three years, accompanied by

carbon savings of over 10,000kg per

year.

This survey revealed the hidden potential

for savings that most building owners or

operators have within touching distance.

A simple task such as replacing old

booster sets can make an enormous

difference, all while giving residents

peace of mind that their shower won’t

be cutting off anytime soon.

Tackling insufficient water pressure

Over recent years, a growing number

of properties have, almost overnight,

experienced a drop in water pressure

despite running for decades without

any issues. As a result, the challenge of

overcoming this issue is one that very

few have experience in solving.

To combat the issue of insufficient

water pressure, the industry’s solution

providers, like Wilo, offer an end-to-end

service to ensure that suitable boosters

are selected, commissioned and, postinstallation,

serviced correctly so they

perform effectively for years to come.

Wilo has worked with the country’s

largest housing associations,

accommodation providers and hospitals,

gaining the necessary experience to

help businesses in a variety of sectors

overcome these water pressure issues.

Accessing available support

Besides needing to deliver constant

pressure, specifiers are also being

challenged to deliver sustainable

solutions as part of the nationwide

focus on improving our environmental

credentials. That’s why, before specifying

any solution, it is important to carry out

on-site surveys and energy reports to

better understand the importance of

installing or retrofitting pressure-boosting

technology.

Energy reports, for example, can help to

illustrate the potential energy, carbon and

cost savings that could be made from an

upgrade. Wilo provides these services

supporting resilient

development all the way

from the ground up.

Part of the Genuit Group, Polypipe

Civils & Green Urbanisation is a

leading manufacturer of water

management and network solutions,

working to enhance sustainable and

resilient development.

In 2020 the business changed its name

to include Green Urbanisation, reflecting

our shift in focus towards a holistic

approach to water retention, re-use and

management – and we also introduced

new techniques that optimise urban

green assets through an extended

and fully integrated sustainable water

management network.

As Specification Director, I’m lucky to

lead a team of technical product experts

across a wide range of disciplines and

applications who work with engineers,

architects and planning authorities at

the early stages of a project to ensure

they benefit from our latest Green

Urbanisation technologies in water

management. For example, we keep

water management at the heart of the

design approach to create new, greener

urban landscapes, be it new or retrofit.

This helps make towns and cities more

resilient to climate change and become

better, more pleasant and healthy places

to live and work. There is no doubt

FROM ROOF TO RIVER

that our climate is shifting, and we

are witnessing more frequent extreme

weather events – Green Urbanisation

has an important role to play in reducing

these impacts, by bringing water closer

to the surface.

Solutions for every application

Our range of award-winning products

includes a variety of solutions suitable

for various applications – from roof

to river. They’ve been designed and

manufactured to encourage a safer

and more sustainable future, helping to

mitigate the effects of climate change

and the impact of urbanisation and

population growth.

Ridgidrain, for example, is a twinwall

surface water drainage system made

from 100% recycled high-strength

HDPE, which won the top prize in

the Building & Construction Products

category at the Plastics Recycling

Awards Europe in 2023.

This year, our Polystorm product has

been nominated for the same award.

The Polystorm geocellular system is

designed to provide surface water

retention, attenuation or infiltration as a

soakaway solution at a variety of depths

in trafficked and loaded areas.

Talking about smart systems

At Polypipe CGU we can provide quality

products and solutions for every stage

of a project, but we’re also passionate

innovators. We know that, together,

we can create sustainable living and,

when we look towards the future, smart

systems can play a huge role in that.

Polysync is our flagship smart system. It

works with our Polystorm and Permavoid

systems, along with a cloud-based

control system, to forecast weather

events and optimise water volumes

stored in attenuation tanks. It’ll forecast

weather activity and then instruct the

tanks to either reduce or maximise their

stored water to accommodate for rainfall

or to maximise potable water storage

for use in the event of a drought. This

groundbreaking system has proven

results in not only reducing costs, but

also improving biodiversity and creating

greener spaces that bring a wealth of

wellbeing benefits.

We keep water

management at the

heart of the design

approach to create

new, greener urban

landscapes, be it new

or retrofit.

Supporting the future

From droughts to flooding, extreme

weather events are becoming

increasingly common in the UK and

we’re also experiencing higher levels

of unpredictability in weather patterns.

Ultimately, global warming and climate

change mean this will remain the case

for at least the foreseeable future, so it’s

time to adapt and make our urban areas

more resilient.

From the use of recycled materials from

our very own Polymer Processing Plant

SPECIAL FEATURE

UNDERSTANDING REACTION TO

FIRE TESTING

Glidevale Protect has

recently launched Protect

FrameSafe FR – a Class

A2-s1, d0 flame retardant

external wall breather

membrane. Jim Smith,

Head of Technical at

Glidevale Protect, explains

the Reaction to Fire

testing process.

Reaction to Fire testing, which

evaluates a construction

material’s level of combustibility,

is an assessed rating of the amount of

protection a construction membrane will

offer against the propagation of fire. But

it’s also important to interrogate these

results beyond whether products are

simply Class B or above.

Start by ascertaining the scope

and integrity of the testing that the

manufacturer has carried out. Has

the product been independently fire

tested in a laboratory by a third party?

Has the membrane been tested both

free-hanging and as part of a system

in an end-use application? Has it been

assessed on different substrates? What

about the fixings? When was the test

carried out – if it was more than three

years ago this can impact on the validity

of the result. It’s also important to look at

the field of application limitations in the

classification report as these explain the

scope of how the membrane should be

used.

In reality, no product is

ever isolated in terms of

fire performance when

used within a building, so

it is therefore likely to be

affected by surrounding

materials within the wall

construction.

Decoding fire test classifications

Within the classification system there are

seven classes from A1 to F, ranging from

products that are non-combustible to

those at the other end of spectrum that

are highly flammable.

Products achieving Class A reaction to

fire ratings should have been subjected

to the most stringent tests covered by

BS EN 13501-1:2018. And, as specified

in this standard, for a lightweight product

like a membrane, two different fire test

methods are required. These are tests to

BS EN ISO 1716:2018, which assesses

the amount of energy released when a

material is completely combusted within

a bomb calorimeter, and also BS EN

13823:2020+A1:2022, which assesses

how a material behaves when it is

exposed to thermal attack by a single

burning item.

The BS EN 13823 single burning item

test method simulates a fire starting in

the corner of a room with material under

test exposed to the development stage

of a fire and monitored for a period of

20 minutes. The purpose is to measure

how a material reacts to a sustained

heat source, including the total heat

release during the period, analysis of

combustion gases generated, level of

smoke production and assessment of

any flame spread or flaming droplets.

The second element of the Reaction

to Fire classification refers to the

smoke generation of the product as

it burns, with three levels of smoke

intensity ranging from s1 to s3. Protect

FrameSafe FR’s s1 rating means there

was little to no smoke generated during

the test. It also measures the amount

of burning droplets created by the

fire. Again, there are three levels, this

time ranging from d0 as the lowest

classification up to d2. Products like

Protect FrameSafe FR with a d0 rating

do not produce any burning droplets

that could potentially spread the fire

further.

Testing the system

In reality, no product is ever isolated in

terms of fire performance when used

within a building, so it is likely to be

affected by surrounding materials within

the wall construction. Glidevale Protect

carried out the same BS EN 13823

test on Protect FrameSafe FR both

with the material as free-hanging and

also mechanically fixed to a substrate

comprising firstly of a Class A1 rock fibre

insulation substrate and then, separately,

with a low-density Class A2 fire board.

The A2 reaction to fire result was the

same, giving specifiers peace of mind

the membrane will perform as well in the

real world as in a laboratory.

SPECIAL FEATURE

ELEVATING ROOFING STANDARDS IN

SOCIAL HOUSING

Wayne Chissell, Technical Director at WestWood Liquid Technologies, advocates for a

proactive approach to health and safety protocols; emphasising the urgency of

improving standards within the UK’s social housing sector.

In the ever-evolving landscape of social housing

refurbishment, there’s a pressing need to ensure not just

compliance but excellence in roofing and waterproofing

standards. Accountability is a critical consideration, and the

current self-regulatory model in roofing and liquid waterproofing

raises concerns. Longevity and safety in housing association

properties should not be left to chance. This underscores

the importance of going beyond minimum requirements and

embracing innovative solutions.

The power of PMMA

Polymethyl Methacrylate (PMMA) systems emerge as a

frontrunner in this endeavour. PMMA technology is not a

new and emerging chemistry but stands out for its versatility

and reliability, as well as ongoing research and development

across the world. Developed nearly a century ago, PMMA

has undergone continuous evolution, making it a durable and

robust solution for various applications including flat roofs, car

parks, and balconies.

Installation advantages

PMMA-based systems offer numerous advantages. They are

solvent-free, cold-applied, and typically comprise of resin and

catalyst components – an ideal choice for occupied social

PMMA doesn’t just offer short-term

benefits, it’s a long-term solution.

With its flexibility and hard-wearing

properties, PMMA ensures

watertightness and durability for up

to 25 years.

housing environments. The rapid curing process, often within

15-20 minutes even in sub-zero temperatures, makes PMMA

ideal for occupied housing blocks. Moreover, its adaptability

to variable weather conditions makes it suitable for the

unpredictable British climate.

Safety first

One of the standout features of PMMA systems is their safety

profile. Unlike traditional methods that involve open flames,

PMMA installation is flame-free, mitigating risks for contractors,

clients and end-users. Furthermore, stringent training protocols

ensure safe and effective installation practices, underscoring

WestWood’s commitment to both safety and quality.

Long-term reliability

PMMA doesn’t just offer short-term benefits; it’s a long-term

solution. With its flexibility and hard-wearing properties, PMMA

ensures watertightness and durability for up to 25 years.

Third-party accreditations such as BBA, ETA, and FM Approval

add further credibility, ensuring compliance with building

regulations.

Collaborative planning

Collaboration is key during complex housing refurbishments.

Balancing budget constraints, time pressures, and resident

safety requires meticulous planning. PMMA systems streamline

this process, offering quick and easy installation without

compromising on quality or safety.

Specifying PMMA liquid applied waterproofing for social

housing refurbishment represents a leap forward in elevating

roofing standards. With its blend of durability, safety, and ease

of installation, PMMA has emerged as a beacon of innovation

in the construction industry. By embracing this technology,

housing associations can ensure not just compliance but

excellence in their refurbishment projects, ultimately enhancing

the quality of life for residents.

ESSENTIAL GUIDE TO RENDERS AND

DECORATIVE FINISHES FOR MMC

Specifiers can now access a free guide to incorporating

traditional decorative finishes into modern methods of

construction (MMC).

With the Government increasingly expressing its

commitment to MMC, specifiers must explore new ways of

delivering projects using MMC while catering for Britons’

love for traditional brickwork.

The Essential Guide to Renders and Decorative Finishes

for MMC guide from Saint-Gobain Weber explains how premanufactured

value (PMV) is attained and gives an overview

of the most common types of MMC and materials, as well as

the different finishes that can be used with these methods of

construction.

One area where it’s easy to specify a PMV-improving

element is using modern alternatives to traditional brickwork.

Weberwall brick provides a realistic and timeless brick-effect

finish without using actual bricks. This fast-fix alternative to

brick slips can be used internally, and for refurbishment and

newbuild projects.

CASE STUDY

IT’S NOW EASIER TO DO THE RIGHT

THING BY BATS

It’s becoming increasingly important to consider the environmental impact of new building

projects, especially when it comes to the natural habitats of protected wildlife species such

as bats. Manthorpe explains how a new roofing solution could help.

Finding suitable roosting spots

in urban areas has become

increasingly difficult for bats in

recent years due to improved building

practices and materials that reduce

defects. However, the Manthorpe Bat

Ridge Roost provides a solution by

offering these important pollinators a

new home among the rooftops.

This product is the result of a partnership

between Manthorpe and the bat experts

at the Bat Conservation Trust (BCT).

By tapping into the BCT’s extensive

knowledge of bat behaviours and needs,

the Ridge Roost provides an optimised,

purpose-built roosting habitat for small

crevice-dwelling species right here in the

UK.

The field monitoring process includes

partnering with Vistry Group to install

Ridge Roosts at one of their new

development sites through the BCT’s

Roost Partnership Scheme, opening

up more opportunities for ecologists,

researchers, and bat enthusiasts to

observe these fascinating nighttime

creatures in their urban habitats.

What makes it so bat-friendly?

Let’s start with the prime location – the

product is situated at the roof’s apex

acting as the ridge end cap itself, and

this elevated spot gives bats that high

vantage point they crave, with a secure,

With the growing

emphasis on

environmentally

friendly building

solutions, it’s crucial

that new products don’t

impede construction

schedules.

self-contained space offering protection

from predators and the elements.

But the benefits go beyond just the

location. The interior was carefully

designed with real bats in mind. Climbing

grooves and a rougher recycled polymer

surface allow easier manoeuvrability

inside the roost while thermal testing

and an insulated inner chamber create a

temperature-stable environment. Multiple

prototypes were refined before landing

on the final shape and textures to seek

the bats’ approval.

With the growing emphasis on

environmentally friendly building

solutions, it’s crucial that new products

don’t impede construction schedules.

The Ridge Roost meets this need

through its versatile design, which

is suitable for both newbuild and

refurbishment projects.

The two-part installation seamlessly

integrates with both dry verge

systems and traditional verge details,

allowing for easy adoption by housing

developers without disrupting timelines.

A key advantage is the roost’s exterior

mounting location, which provides

dedicated bat housing while ensuring

there are no entry points into the roof

space itself.

From a thermal design backed by

university testing, to construction that

meets modern aesthetic standards,

and installation that integrates with your

current building methods – it’s clear the

Ridge Roost was developed with the

construction industry’s needs in mind.

But, most importantly, it answers the call

for sustainable solutions that support

biodiversity in the urban environment.

So, whether you’re planning a new

residential development or renovating an

existing property, keep the Manthorpe

Bat Ridge Roost in mind. Your bat

neighbours will appreciate you giving

them a safe place in the community.

SPECIAL FEATURE

SUSTAINABILITY GETS A BOOST AT

SOCIAL HOUSING SCHEME

A range of product solutions from leading manufacturer Glidevale Protect has been

specified and installed to help create energy-efficient and healthy homes on a new

affordable housing scheme in Swansea.

The Samlet Road development in

Llansamlet, Swansea, has seen

contractor, Castell Group, create

35 new homes, comprising a mix of

one- and two-bedroom apartments and

two- and three-bedroom houses, in

partnership with social housing provider

Caredig. The newbuild development

has been designed with a fabricfirst

approach and includes a host of

sustainable features including integrated

in-roof solar PV panels. Glidevale Protect

was on hand to provide a combination

of a high-performance pitched roofing

membrane and ventilation solution to

meet the project’s specific requirements.

Glidevale Protect supplied products

from across its roofing and construction

membrane ranges, including the new

Protect A1 Solar pitched roofing underlay

– a heavy-duty type HR impermeable

roofing underlay. It is designed for use on

all cold and warm pitched roofs where

in-roof solar PV panels are installed.

When used with the correct ventilation

strategy, the underlay reduces the risk of

interstitial condensation forming on the

underside of solar PV panels.

To further reduce the risk of

condensation forming in the roof space,

Glidevale Protect also provided a

selection of roofing ventilation solutions.

These included over fascia vents and

rafter rolls to achieve low-level ventilation

at the eaves and the Protect Fulmetal

UniRoll dry-fix ridge and hip system

for high-level ventilation at the ridge.

The flexibility of Glidevale Protect’s

roofing solutions enabled them to be

installed throughout the scheme, which

comprises a mix of timber frame houses

and flats as well as traditional masonry

build apartments.

The timber frame homes feature

Glidevale Protect’s low emissivity TF200

Thermo reflective external wall breather

membrane to help achieve lower wall

U-values and improve the thermal

efficiency of the properties.

Supply chain collaboration was vital to

the project’s successful delivery, with

the technical team at Glidevale Protect

working closely with specialist roofing

contractor Alex Baul Roofing and the

Castell Group to devise a suitable

ventilation specification to accommodate

the solar PV roofing elements. Glidevale

Protect also worked with established

supply chain partner LoCal Homes, part

of the Green Square Accord Group.

LoCal Homes provides both traditional

and closed panel timber frame systems,

working with contractors and housing

associations to create award-winning

affordable housing that can be produced

at volume and pace.

Donna Rosser, Commercial Manager

with Castell Group, said: “The use

of solar PV panels throughout the

Samlet Road housing development is

a key feature and one that has been

integrated specifically to improve the

energy efficiency of the properties

and contribute to lower fuel costs

for residents. It’s vital that the roofing

membrane and ventilation system works

as efficiently as possible and the risks

of any moisture ingress behind the solar

panel arrays are minimised. We needed

a robust solution and Glidevale Protect

proved to be the perfect partner in terms

of its wide range of roofing products

available, as well as the technical

support and expertise the team brought

to the table.”

Mike Doolan, Sales and Partnerships

Manager at LoCal Homes, said: “Our

ethos is built on partnership and

collaboration and having worked with

Glidevale Protect for upwards of seven

years, we consider them a key supply

chain partner. We chose to use Glidevale

Protect products on this project

because of their quality and reliability of

performance. We work within a fabricfirst

design and the excellent aged

thermal resistance of Glidevale Protect’s

reflective membranes allow us to easily

meet the low wall U-value requirements

of both our open and closed paneled

systems.”

The scheme has been shortlisted in two

categories, Building Project of the Year

and Residential Property of the Year, at

this year’s Constructing Excellence in

Wales Awards.
