IBSTOCK <strong>DESIGN</strong> •AUTUMN 2016 •7
Nottingham Trent University’s brief to architect<br />
Evans Vettori wastoreplace or modernise a<br />
number of worn-out 1960s teaching buildings on<br />
an unpromising site to provide state-of-the-art<br />
spaces. A‘front door’and student ‘heart’ to the<br />
campus wererequested, and the buildings wereto<br />
be highly sustainableand low-energy.<br />
The new socialcentre–the Pavilion –is<br />
augmented by anew teaching building, set at right<br />
angles. By relating these to an existing lecture<br />
theatrebuilding, on thehypotenuse, atriangular<br />
Plaza iscreated, forming afocal point to the<br />
campus and providing coherence to thesite.<br />
The Pavilion is raised on asheltered, south-facing<br />
plinth with viewsacross the plaza. Precast concrete<br />
roof vaults providethermal mass and asense of<br />
permanence, while the wallscomprise redand<br />
grey brick, reflecting the local context. The main<br />
north-south and east-west pedestrian routes are<br />
defined by colonnades.<br />
The 2,000-square-metrePavilion formsanew front<br />
doortothe campus, providing acentral building<br />
for students with large andsmallspaces for<br />
collaborative learning and social interaction. The<br />
colonnade concept was generated by the primary<br />
east-west pedestrianroute, and it shades thesouthfacing<br />
facade. The structureturns at the west end,<br />
formingacovered bridge which accesses the three<br />
new lecturetheatres and defines the ‘quad’, with a<br />
new entrance to the library.<br />
The groundfloor is mainlygivenover to the<br />
Forum–aflexible,high-quality,IT-rich space for<br />
meeting and working in arelaxing, social<br />

environment. The Forum is augmented by more<br />
enclosed learningspaces to the rear,while cosier<br />
alcove spaces areprovided inthe ‘pods’ along the<br />
front elevation. The mezzanine floor offers quieter,<br />
moreintimate areas for study and social<br />
interaction, including flexible teaching rooms.<br />
The 2,100-square-metreTeaching Building, which<br />
has replaced several demolished buildings,<br />
contains large, state-of-the-artclassroomsand<br />
lecturespaces. Aclear external route is provided<br />
through the building to link the Plazawith<br />
outlyingareas. The building plays asupporting<br />
role in the ensemble of new buildings around the<br />
Plaza, and its architectural language complements<br />
that of the Pavilion.<br />
The large lecturespaces areaccessed externally<br />
from the raised colonnade. The elevations express<br />
the steel-framed structuralgrid and make use of<br />
multi-coloured brickworktodefine openings.<br />
Textureand grainare provided by varyingthe<br />
brick coursing.<br />
The upper floor contains three large lecture<br />
spaces. The central space has tiered seating, while<br />
the two on either side areflat-floor, allowing<br />
flexible furniturearrangements for different<br />
teaching modes. The lower floor has 10 classroom<br />
spaces of varying sizes. It is possibletojoin threeof<br />
these to formalarge flat-floorspace for ‘scale-up’<br />
teaching and other large-format configurations.<br />

generous double-height<br />

architects to suggest a<br />

the surfaces to add<br />

Sweeping<br />
Impressions<br />
Stylish curved walls of brick<br />
envelop the free-flowing<br />
and flexible interior spaces<br />
in Adrian James Architects’<br />
re-invention of the archetype<br />
‘villa in the landscape’.<br />

IBSTOCK <strong>DESIGN</strong> •AUTUMN 2016 •13
‘Incurvo is ameta-villa’, saysarchitect Adrian<br />
James. ‘Like aclassical villa it sits at the centreofa<br />
beautifulsculpted landscape. But unlike aclassical<br />
villa it does not sit four-squareonaxis, gazing<br />
haughtilydown on aformal landscape in stasis.’<br />
‘Incurvo is all about movement. It is fluid; a<br />
dynamicsensuous formwhich beckons the visitor<br />
around its sweeping curves. This is abuilding that<br />
growsout of the organic curves and folds of its<br />
setting. The house is aviscousformpetrified; it is<br />
an English butte. The strong sense of movement<br />
embodied in the shape is frozen in time within its<br />
brick carapace. The localbrick has aluminous<br />
earthy orangehue, seeminglystill bright from the<br />
heat of the kiln; this house exploits both the<br />
extraordinary plasticity of the humble brick, and<br />
its rough, tough sense of rootedness.’<br />
‘Inside, too,isall about curves and movement;<br />
aloftyentrance hall draws visitorinwardsand then<br />
left, right and up as the space opens and diverges<br />
in all directions. The destinations, the places to<br />
pause and rest, arethe foci of the majestic curved<br />
windows which offer breathtaking panoramicviews<br />
of the garden, water,trees and rolling Chilterns<br />
landscapebeyond.’<br />
‘Incurvo is not just apretty face, however.Itisas<br />
close to being aPassivhaus as acurvy house can be.<br />
The radial windows preclude full compliance, but<br />
the house meets the most stringent benchmarks<br />
for insulation, thermal bridging, airtightness and<br />
thermal comfort. Passivhaus principles have been<br />
adhered to throughout, with aCertified Passivhaus<br />
tradesperson overseeing the entireconstruction.<br />
The end result is adwellingthat will have<br />

Adrian James writes:<br />
In 1973, the celebratedarchitect Louis<br />
Kahn wrote: ‘You saytobrick,“What do<br />
youwant, brick?”And bricksaystoyou,<br />
“I like an arch.”‘<br />
Apresent-dayconversation might go:<br />
Yousay to brick,“What do youwant now,<br />
brick?”And bricksays:“Look,Istill love an<br />
arch,ofcourse! But Iappreciate that<br />
technology has movedon. Nowadays the<br />
loadbearing job is necessarilywithin an<br />
insulating envelope; whateverbearsthe<br />
weight has to be separated from the<br />
external finish to prevent cold bridging.<br />
Therewas atime –afew millennia in fact<br />
–when Icould be structureand finish<br />
simultaneously. But those days areover.<br />
Nowthereare other materials that can do<br />
the loadbearing and Iammorelikelytodo<br />
the external cladding alone.”<br />
“That is notaproblemthough!And<br />
certainlynot ademotion. Ihave qualities<br />
beyond compressivestrength,and,ifI’m<br />
notcarryingall that internal load,that<br />
frees me up to exploit them.For astart,<br />
Ihave extraordinary plasticity.Mysmall<br />
handyshape means thatangles,cranks,<br />
curves areadoddle–nospecial<br />
fabrication,just me doing what Idobest.”<br />
“Beingthe face of the building,freed<br />
from structuralduties, givesmescope<br />
to be supple and sinuous. Ican be like the<br />
skin of an athlete, ataut layerhugging<br />
andexpressing the musculature<br />

three energy generation systems: alarge arrayof<br />
photovoltaic panels on the roof, an array of solar<br />
thermal panels to heat domestic water,and afull<br />
mechanicalventilationsystem with heat recovery.’<br />
‘Incurvo willbeextremely comfortabletooccupy.<br />
It has beendesigned as aLifetime Home, with<br />
space for alift,generous dimensions and internal<br />
flexibility.And it hasbeen builtusing extremely<br />
durable materialsrequiringminimal maintenance.<br />
This house is designed to last for many lifetimes<br />
with the lightest of touches on the planet.’<br />
‘The structureisanenhanced ICF (Insulated<br />
Concrete Formwork)system, with aU-value of<br />
0.14. This constructionmethod combines<br />
continuous insulationwithstructural flexibility and<br />
airtightness in onerobustelement. In-situ concrete<br />
floors and roof (withevenbetter U-values of 0.l)<br />
create acontiguous thermal and airtight envelope<br />
and cope with the non-orthogonal formand large<br />
cantileversover the wide curved openings. This<br />
isahousewhich stretches the capabilities of the<br />
building systems to the limit. The long stretches of<br />
curved walls required awhole new approach and<br />
real craftmanship from theICF supplier to make<br />
the tied radial insulating formwork.’<br />
‘Therehas beenunstinting attention to detail<br />
throughout the design and construction of<br />
Incurvo’, saysAdrian James. ‘But at no time has<br />
the pursuitofexcellence in sustainability or<br />
constructionbeen allowed to compromise the<br />
poetic idea of the house. Everything, everyone<br />
has worked together to make it real.’<br />

The design responds to the existing grainofthe<br />
schoolsite, whichischaracterised by aseries of<br />
courtyards and quadrangles. The two new<br />
interventions –the Bean LRC and the Cunliffe<br />
Building –emphasise this approach, physically<br />
connecting the school’s central gardens through a<br />
new arcade. This arcade takes its cue from anearby<br />
cloister and informsthe rest of the elevation,<br />
creating an arrayofarchesthat formapicturesque<br />
backdrop to themuch-used ‘stage lawn’.<br />
In seeking to respond to the existing built context,<br />
both buildings areclad in redbrick and composed<br />
in similar proportionstothe neighbours. Asubtle<br />
brick patterning (English Bond)used on the<br />
Cunliffe Building adds visualinterest to the facade.<br />
The existing two-storeyBean Library, completed<br />
in 1929 and named after EdwinBean (headmaster<br />
from 1891-1913), encompassed two floors at the<br />
centre of the campus, but it was unable to<br />
accommodate the present-day needs of the<br />
school’s 1,200 pupils. The oldlibraryhas been<br />
retained on thefirst floor,preserving the character<br />
and integrityofthe building and contrasting with<br />
the contemporary spaces.<br />
IBSTOCK <strong>DESIGN</strong> •AUTUMN 2016 •27
As well as creatinganew education hub, the<br />
ground floor of the libraryincorporates a<br />
dedicated social area. An entrance portico links<br />
the study and socialareas withatransition space<br />
that can be used for talksand lectures. With large<br />
classroom spaces, alecturetheatre, cafe and places<br />
for individual andcollaborativestudy,itprovidesa<br />
state-of-the-art, resource-rich environment<br />
intended to help students develop independent<br />
learningskills. The libraryfeatures improved<br />
access to books and electronic resources and<br />
includes adigital learninghub wherestudent<br />
‘digital leaders’ areonhand to help other students<br />
and staffdevelop their digital literacy.<br />
The new assemblyspace and lecturetheatreevoke<br />
auniversity-stylelearning environment with<br />
seminarand workshop areas. It is flanked by anew<br />
arcadethat provides external social space and acts<br />
as averanda to the ShakespeareGarden.<br />
The adjacent Cunliffe Building, previously<br />
containing classrooms for classics, learning<br />
supportand first-form tutor groups, now contains<br />
eight classrooms equipped with cutting edge<br />
technology,including computer suites, interactive<br />
whiteboards, giant projectorscreens, and Apple<br />
TV systems which can connect multiple iPads to a<br />
largescreen. In addition, the building includes the<br />
relocated sanatorium, now better positioned at the<br />

neighbourhood-focused, street-based masterplan,<br />
intended to transformthe formerlyisolated,<br />
inward looking estate into awell-connected,<br />

sense of place and identity.The masterplan<br />
incorporates aseries of ‘character areas’ which<br />
not only provide asense of variety anddistinction<br />
to each street and public space, but also connect<br />
them with their immediate context, as well as the<br />
conservation areas that surround the estate.<br />

Radial<br />
Brickwork<br />
Radialbrickwork cansignificantly<br />
enhance the appearance of a<br />
building, by adding adesign<br />
featurethat can engage withthe<br />
context, express the internal<br />
activities, or suggest streamlined<br />
glamour.Wetend to think that<br />
radial brickworkmeans using<br />
moreexpensivespecial bricks.<br />
This may be true for the glazed<br />
radialssuch as those, for<br />
example, on the featurestair<br />
towersatKillorglinAreaCentre<br />
in County Kerry,Ireland (Murray<br />
O’LaoireArchitects ), wherethe<br />
radius of 1650mm justifies their<br />
use, but it’s not alwaysthe case.<br />
At the Sixth Form College<br />
building in Worcester,byQuattro<br />
Design Architects, it was possible<br />
to use standard bricksinacurved<br />
featurethat was justwithin the<br />
minimum radius of thefour<br />
metres Ibstock would normally<br />
recommend. With their highly<br />
reflectivesurfaces, glazed bricks<br />
can be the least forgiving when set<br />
out on aradius, but even with the<br />
sun shining on them the<br />
cylindrical tower at Worcester<br />
looks veryeffective. The architect’s<br />
careful consideration of the brick<br />
modularsizing forthe window<br />
openings and piers between them<br />
has done much to enhance the<br />
appearance.<br />
Itispossible to achieveeven<br />
tighter radiiwith standard bricks<br />
and avoid an overly facetted<br />
appearance. This does however<br />
require theuse of aHeader Bond<br />
to exploitthe narrower102mm<br />
face. Herethe consideration<br />
concerns not so much the faceting<br />
of thebricks but rather getting<br />
sufficient mortar between them on<br />
the inner intrados of the radius<br />
whilst not having the joints too<br />
wideonthe extrados.<br />

Warwick University show two<br />
setting-out alternatives. Option A<br />
shows the external perpend<br />
joints at 11mm and the inner at<br />
3mm, which would have been<br />
more difficult to build due tothe<br />
mortar not compressing easily<br />
down to 3mm, leaving the<br />
possibility of only part ofthe<br />
joint being filled with mortar.<br />
Option Bhas 6mm internal<br />
joints, which can be more readily<br />
built, and 15mm joints on the<br />
outside, a4mm increase that<br />
generally goes unnoticed.<br />

this buildingthe edges of the bricks<br />
wererebated to allow them to nest<br />

Adrian James Architects’ Incurvo<br />

Bond can be used to achieve a2m<br />
radius using standard bricks.<br />
The combination of headers and<br />
stretchers, together with astack<br />
brick with its rounded arrises and<br />
arecessed mortar jointing, will<br />
gently facet the bricks around a<br />
fairly tight radius. Extruded<br />
bricks built with aflush orbucket<br />
handle joint may not be quite as<br />
forgiving at this radius. Like<br />
Adrian James Architects at<br />
Incurvo, therefore, we would<br />
advise specifiers toconsider<br />
having asmall sample panel built<br />
to provide reassurance that the<br />
radiused brickwork meets with<br />
the aesthetic expectations.<br />

Birtley<br />
Brickworks<br />
Ibstock’s Birtley factory–hometo<br />
three brickworks over aperiodof<br />
morethan 100 years –today<br />
employs45people at its County<br />
Durham site.<br />
Until 1972, Birtleyproduced<br />
handmade and extruded type<br />
bricks but with the installation of<br />
itsfirst Petersen machine, and two<br />
yearslaterasecond, the Birtley<br />
factorybegan instead to produce<br />
authentic waterstruck bricks.<br />
Today it is thought to be one of<br />
only two factories countrywide to<br />
do so. Rather than using sand or<br />
oilstorelease the pressed clay<br />
from the moulds, water is used,<br />
helping to create the highly<br />
prized and uniquelytextured<br />
appearanceofthe bricks.<br />
The use of the high quality<br />
Petersen machines means that the<br />
bricks aretruly sustainable, and as<br />
they arekept operating seven days<br />
aweek, Birtleyiswell equipped to<br />
meet the demand for its products.<br />
This factoryalone achievesan<br />
output of around25million<br />
bricks per year,withamixtureof<br />
both65mm and 73mm bricks.<br />
Even though Birtley’s main focus<br />
is the waterstruck brick, it also<br />
specialises in rumbled bricks and<br />
non-standard linear bricks up to<br />
440mm in length. Additionally,<br />
Birtley produces unique blends and<br />
colour combinations to meet<br />
individualrequirements. These are<br />
made using afull palette –from<br />
reds through to greys –which<br />
means truly unique colour<br />
combinations can be producedfor<br />
use whereatraditional brickisnot<br />
appropriate for aparticular project<br />
or where the client wants to create a<br />
distinctive façade.<br />
Significantly,Birtleyhas worked<br />
with thecelebrated designer Stella<br />
McCartney to produce special<br />
bricks and the factoryiscurrently<br />
working on aprojectwithsculptor<br />
Sir Antony Gormley on an<br />
innovative artwork that seeks to<br />
explore the special characteristics of<br />
the Birtleyclay.Gormley’s ‘Angel of<br />
the North’ (1998) is located to the<br />
north of Birtley,and its profile<br />
features in the brickmaker’s logo.<br />
The factory’s products have come<br />
to be used in many major projects,<br />
and this has beenrecognised<br />
through its success in the BDA’s<br />
Brick Awards over anumber of<br />
years. It has also been commended<br />
for sourcing responsibly to BES<br />
6001, for being environmentally<br />
accredited to ISO 14001 and being<br />
the first brick factory to achieve ISO<br />
50001 for energy management.<br />

Response:<br />
Simon Gould<br />
What factors tend to lead you to<br />
use bricksinaproject?<br />
The quality and richness of the<br />
finished product that we andthe<br />
client aspiretoo; the project<br />
location and built context; and<br />
the budget. Ipersonally love using<br />
bricks to make places because<br />
they bringsomuch playful<br />
opportunity to aproject. It is<br />
quite extraordinarythat aproduct<br />
with astandardmodule of 215x65<br />
x102.5mm can be used to give<br />
formtosuch avarietyofbuildings<br />
and places.<br />
What can bricks offer in termsof<br />
creativity?<br />
My early memories of massive<br />
industrial structures and civic<br />
buildings in the West Midlands<br />
have informed my view that brick<br />
has limitless opportunities. From<br />
heavy,moody volumes to delicate,<br />
refined structures, one can use<br />
brick to create allmanner of<br />
different surfaces, walls, floors and<br />
roofs. Bricks arenot justred –<br />
from their raw claystate through<br />
the firing process to the finished<br />
article thereare many<br />
opportunities for them to be<br />
made into atotally different type<br />
of product. Also, bricks can be<br />
stacked and bondedina<br />
multitude of ways, and one mustn’t<br />
forget the all-important mortar that<br />
completes the palette.<br />
Which brick projects by Mitchell<br />
Eley Gouldhave pleasedyou most?<br />
King’s College library –wewere<br />
asked by the Taunton schoolto<br />
build alibraryasanextension to a<br />
grade-twolistedbuilding of locally<br />
quarriedstone. We were facedwith<br />
the challenge of complementing<br />
and enhancing the built setting,<br />
but thequarry had long since<br />
closed. We thereforedecided to use<br />
amix of five different bricks, one of<br />
which was aklinkerbrick that had<br />
beenstamped on and distorted<br />
beforebeing fired. Afat,flush<br />
mortar joint made the individual<br />
elements read as acohesivewhole.<br />
Initially therewas some doubt as to<br />
whether theproposed blend of<br />
materials would work, but five years<br />
on thebuilding is full of character<br />
and charms its users.<br />
Kingswood Classroom Buildingis<br />
located in Bath conservationarea,<br />
and theplanning officer requested<br />
that Bath stone be used. We argued<br />
that another prominent materialin<br />
the city was slate, andthat long<br />
slate-coloured blocks would be<br />
appropriate for the walls.They<br />
agreed, and we identified black<br />
Fireborn bricks for the purpose,<br />
with anarrow5mm mortar jointto<br />
create amorerefined surface. The<br />
end product is adark, engineered<br />
facade that plays in acompelling<br />
manner offthe neighbouring soft<br />
Bath stone.<br />
Which projects by other architects<br />
have impressed or influenced?<br />
SigurdLewerentz and AlvarAalto<br />
createdverydifferent buildings<br />
but both made brick structures of<br />
character and charm, along with<br />
raw spatialqualities that inspire.<br />
Is brick amaterial of thefuture?<br />
Of course.Bricks have beenused<br />
for hundreds of years to create the<br />
places that we inhabit andIbelieve<br />
we will continuetouse bricks for<br />
many moreyears to come<br />
