Collective Architecture, on behalf of Queens Cross Housing Association, has developed proposals for the refurbishment of 3 blocks of flats, originally built in the late 1960s. The proposals for Cedar Street and Cedar Court are pioneering on an international level and will bring the Cedar ‘Multis’ to the forefront of energy performance in the UK. Currently targeting the Passivehouse EnerPHit standard for retrofit, the proposals are a significant improvement over current building regulations, with the intention of mitigating fuel poverty for the 314 homes within. As much as an 80% reduction in space heating demand is targeted.
