External Building Envelope THE FUTURE OF URBAN DEVELOPMENT IS LOOKING UP Estimates vary on how many homes could be created in UK cities by extending buildings vertically. Recent studies suggest that there may be space for as many as 20,000 to 40,000 new rooftop dwellings in the centre of London alone. Furthermore, The National Planning Policy Framework (NPPF), as of July 2018, includes specific reference to in support of upward living. The document states that planning decisions should support the use of the ‘airspace’ above buildings especially if “the development would be consistent with the prevailing height and form of neighbouring properties and the overall street scene”. The availability of land, particularly in cities, is a significant challenge to meeting the current demand for housing. Roof Top Developments (RTD) negate this issue by utilising the existing building with no need to find new land and enable the creation of additional storeys without increasing the overall footprint of the building. The added value of this approach is that, unlike the majority of greenfield developments, it allows much needed housing to be created in the areas of cities where land is most scarce. Furthermore, the planning permission process is often much simpler as the transport infrastructure and amenities are already in place. One of the most effective ways of achieving upward extensions to buildings is through the use of modular and panelised building solutions. These RTD systems consist of a lightweight, robust steel frame construction, which can be built into panels off-site, craned into position and assembled. The external cladding, insulation and finish can then be applied, and the new flats connected to the building’s services. The properties can then be fitted out in the same way as a traditional build. This innovative approach by Langley enables the building to benefit from any number of additional storeys providing planning permission can be secured, the existing building has enough structural capacity and the layout allows sufficient access for residents. In some cases, a structural frame can be used to support the additional storey. This is added to the outside of the building and concealed with cladding to maintain the aesthetic of the building. In addition to utilising the existing roof space, vertical development using modern methods of construction also has a number of specific benefits over building on green- or brownfield sites. As there are no costs for the ground works that would be required for a new or in-fill development, homes can be created at a much lower cost per unit. This cost effectiveness is particularly valuable for social housing providers and local authorities where making best use of often limited capital is vital. Additionally, panelised RTDs provide an increase speed within the construction process, reducing time on site. The work can often be carried out while the building is still occupied, further minimising the disruption for current residents. Despite the benefits of extending upwards, one of the barriers to widespread adoption is acceptance by building owners and leaseholders. Here there is scope for local authorities, housing associations and the build to rent sector to lead the way in normalising the approach. These organisations can, and in some cases, are already, engaging with their tenants to explain the intended work and formulate a plan that will deliver tangible benefits to existing residents. Adding a further storey delivers best value when planned as part of a wider regeneration of the property. Once a template for development has been created the process can be replicated across a number of buildings to maximise the use of land in an area. Roof Top Developments offer a quick, simple and cost-effective way of creating additional dwellings, supporting existing communities in towns and cities. While small scale vertical extension of private homes is not a new concept, the largescale developments that will help address the issues with housing demand in cities has not yet achieved widespread adoption. Despite this, recent changes in government policy and forward-thinking organisations embracing the concept have helped begin this process and give developers confidence in the model. www.langleystructures.co.uk 38 Feb 2019 <strong>M11</strong>
