With its mix of new homes, modern office space and active retail frontages, 121 Upper Richmond Road improves the streetscape and enlivens the heart of London’s SW15 to provide a catalyst for urban regeneration in the area. A series of volumes – cascading down from 12-storeys to six – sit atop a podium of two parallel rectangular wings which are set apart to create an entrance and public space on one side and a private rear courtyard on the other. Above, the brick-clad volumes interlock to afford each of the 76 apartments dual-aspect orientation, exploiting views to the north and light from the south. Upper penthouses are stepped away to create private south-facing terraces. The building’s stepped, dovetailing design language is expressed coherently at multiple scales, from the overall massing through to the relief brick texture.
