In 2010, this three-storey property was part of an innovative experiment to reduce the carbon emissions of existing social homes by 80%. Architects Paul Davis and Partners submitted a proposal to produce the UK's first certified Passivhaus refurbishment and the result is a robust domestic space that uses more than eight times less energy per square metre than the average house. Energy consumption has been cut by 94% saving the tenant in excess of £900 a year on fuel bills.In 2010, this three-storey property was part of an innovative experiment to reduce the carbon emissions of existing social homes by 80%.

Originally built in around 1840 and owned by social landlords, Octavia Housing, the top-to-toe transformation of this humble terrace cost a total of £179,000. It incorporates three water solar thermal panels tucked behind the parapet at the top of the front facade and a mechanical ventilation heat recovery system in the basement.Originally built in around 1840 and owned by social landlords, Octavia Housing, the top-to-toe transformation of this humble terrace cost a total of £179,000.

Local conservation requirements stipulated that windows and doors had to remain in keeping with neighbouring properties, so imitation sash windows were triple glazed and the letterbox subtly recessed into the brickwork to reduce the likelihood of any thermal bridges. The difficult issue of internal wall insulation and airtightness was tackled by lining the shell of the building with a continuous box, resulting in a home that is 10-20 times more airtight than most current building projects. Chimney breasts have been removed to reduce the space lost through insulation.Local conservation requirements stipulated that windows and doors had to remain in keeping with neighbouring properties, so imitation sash windows were triple glazed and the letterbox subtly recessed into the brickwork to reduce the likelihood of any thermal bridges.

With no need for a central heating system or radiators, this previously damp and draughty house has been intelligently transformed into a warm, comfortable home.
