we designed a semi buried detached annex building to replace existing garages next to a large flatted development in the heart of east twickenham conservation area. whilst we introduce a classical front facade to the main road, the main body of the building separated by a terrace consists of two floors with bedrooms at lower ground and living, dining and kitchen above. a ‘living wall’ elevats towards the four-storey main building with cor-ten steel clad to all other elevations. despite its small arrangement and stunning design . the concept has been issued for planning with richmond council.
