Clapham is Victorian terraces around the common. The dominant stock — victorian terraces, edwardian villas — has specific constraints and opportunities for loft conversion drawings. Side returns sit better on bay-fronted Victorian terraces than on detached 1930s semis. Mansards work where the existing roofscape supports them. We design to the block, not the brochure.
