Brockley is Victorian and Edwardian terraces. The dominant stock — victorian and edwardian terraces — has specific constraints and opportunities for house extension 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.
