Westcoast is pleased to work with contractor and modular manufacturer, Boutique Modern, to supply aluminium timber windows for 32 new low-cost housing homes in Lewes.

The new Lewes low-cost housing homes will be built on the site of the former Pells Church of England School, which closed in 2017, and will provide one, two, and three-bedroom homes for affordable rent and shared ownership. The construction is the latest net zero carbon development by Surrey and Sussex-based housing provider, Raven Housing Trust.

Raven has committed to achieving net zero carbon emissions by 2050 and was recently awarded sustainability funding as part of Reigate & Banstead Borough Council’s bid to the Social Housing Decarbonisation Fund (SHDF) Wave 1.

As well as being Raven’s second completely net zero carbon development, the 32-home site in Lewes will be their first to be built using Modern Methods of Construction (MMC), a construction technique focussing on building more high-quality homes, faster.

The homes will be factory produced; they will then arrive on site in large box form, where they will be craned into position and the final external insulation and finishes will be applied. This will significantly reduce construction waste and the number of deliveries to site. The factory itself is located within the Lewes district, only ten miles from the site.

The new homes are due to be completed by Spring 2024, and will be built using Homes England funding, as well as Raven’s own funds in addition to a £630,000 grant provided by South Downs National Park Authority.

Aluminium Clad Windows with an average U-value of 0.88 W/m²K

Westcoast is supplying 305m2 triple glazed windows and doors, in aluminium clad timber, manufactured by our sister company Outline, based in Denmark.

The windows achieve an average U-value of 0.88 W/m²K to enable the development to meet the carbon zero criteria.

The windows will be delivered direct from Denmark to the production facility in Newhaven where they will be installed into the modules, then delivered and constructed on site in Lewes.
