Fraser Brown MacKenna unwraps Thamesmead retrofit

[FIRST LOOK + DATA] Fraser Brown MacKenna Architects has completed this end-of-terrace residential retrofit in Thamesmead, south east London

The building, which won a CIBSE Building Performance Award last month, was part funded by the government’s Retrofit for the Future initiative, which aims to improve energy efficiency in social housing.


Wolvercote Road before construction

Owned by Gallions Housing Association, the home on the Thamesmead Estate was constructed using a pre-cast ‘French Balency’ system with a minimal 50mm layer of insulation and single glazing. The addition of superinsulated external cladding and triple glazing throughout has achieved an 87 per cent reduction in CO2 emissions.

Fresh air is provided by a mechanical ventilation system with heat recovery meanwhile renewable electricity and water heating is provided by ten photovoltaic panels and a vacuum tube collector on the roof.

The project is currently being monitored using wireless monitoring equipment to record internal temperatures, CO2 levels, power consumption and energy generation.
