Birchway, Middlesex

The development at Birchway is located in Hayes, on a small tight site in a residential area, surrounded by other houses. The scheme was a flagship project for Paradigm Housing Group, who aimed to create a green community by not only building highly sustainable dwellings, but also by encouraging residents to lead greener lives. We worked with the design team from the early design stages right through to post construction, to help them push the boundaries of sustainable design and construction. We provided tailored advice to aid with designing the measures required to meet the tough energy and sustainability targets required to achieve Code for Sustainable Homes (CSH) Level 5. Each flat is made up of one or more steel framed modules manufactured off-site. The design uses volumetric construction which is inherently air tight, allowing for a larger amount of insulation then traditional construction, which provided both thermal and acoustic benefits to the scheme. The unique curved roofs incorporate green roofing technology to reduce surface water run-off from site and increase thermal properties. The heat and hot water is provided by a communal biomass boiler. A whole house mechanical ventilation system with heat recovery is provided for each dwelling. In addition, a proportion of each household's electricity is provided by PV systems. Our CSH and energy assessors undertook the final as built and post construction assessments. The dwellings achieved CSH Level 5 certification, with an A rating for both energy use and CO2 emissions.
