The Old Timberyard

Built

RDA Architects, Iron Bubble

The project brief was to renovate a previous architect office into a new family home. The client was keen to implement Passivhaus standards; becoming the UK’s first commercial to residential EnerPHit.

Aiming to be the UK’s first Passivhaus commercial to residential family home conversion, pushing the boundaries in converting old building stock. Originally an old workshop once converted to an office, this central London building is getting its third lease of life by adding a basement, front extension and barrel-vaulted roof. With the aim of achieving EnerPHit certification, focusing on high-quality insulation, airtight construction, an MVHR system, quality workmanship and thermal bridging, elevating this retrofit to the highest quality.

Originally an old workshop once converted to an office, this central London building is getting its third lease of life by adding a basement, front extension and barrel-vaulted roof, transforming the building into a family home. The use of the previous structure dramatically reduces carbon emissions through a reduction in materials, transport and labour. With the aim of achieving Passivhaus and EnerPHit certification, the project focuses on high- quality insulation, airtight construction, an MVHR system, quality workmanship and thermal bridging. In construction, timber has been used where possible and a conscious limitation of steel keeps the building’s CFC footprint low.
