CSh4 Housing Development

Bridgwater, Somerset

The Old Apple Store in Stawell was the first private sector housing development in the country to be built to Level 5 of the Code for Sustainable Homes.  O2i Design Consultants were commissioned to develop the detailed design scheme and draw up the building regulations plans. 

This small development won the Regen South West Best Sustainable Development award; it also featured as one of four national case studies of sustainable architecture in the Department for Communities & Local Government Sustainable Housing publication: Code for Sustainable Homes. It was also recognised more locally as a finalist in the South West LABC Building Excellence Awards for Best Sustainable Project.

Five timber framed houses were constructed on a brownfield site to incorporate renewable energy and sustainable construction techniques. Three terraced three-bed homes and two four-bed detached houses were designed around a secure courtyard space, to complement the conservation area and have minimal impact on the environment.

Onsite energy production was designed to generate 100% of the minimal electricity demand for lighting and MVHR fans. Wall and roof insulation U values of 0.11 W/m2K are a 100% improvement on the 'dwelling emission rate' of a house built to current Building Regulations.

Oxford Brooks University Research Unit was commission by the Good Homes Alliance to carry out an assessment of the houses' performance against the design criteria alongside a post-occupancy study.
