Why Holland Park

Holland Park's housing pattern shapes the design

Holland Park is Victorian villas around the park. The dominant stock — victorian and edwardian villas — 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.
