Boundary Close, York

Boundary Close is a scheme of eight houses built to high levels of sustainability for York Housing Association, and completed in 2008.

York HA were keen that social housing tenants should benefit from the low running costs which can result from energy-efficient housing. The scheme was constructed using timber frame construction and to high levels of insulation and airtightness. Mechanical ventilation with heat recovery ensured good air quality, and solar collectors on the front roof pitch pre-heated both domestic hot water and the incoming fresh air.

The scheme was built on a tight, urban site where overlooking issues shaped both the layout and the cross-sectional design of the houses, with restricted views to the north and a lower eaves level to get daylight to the rear yards.

To the south side, extensive glazing, with an oversailing roof and a first floor balcony, provided good dayighting and passive solar gains, while avoiding the risks of overheating.
