House Extensions in Herne Hill
Herne Hill is a well-established South London neighbourhood in SE24 — popular with families and professionals drawn to Brockwell Park, a strong local food and restaurant scene, and large Victorian and Edwardian houses that offer significant improvement potential. RCB Design & Build delivers extensions, loft conversions, and full refurbishments across SE24.
House Extensions in Herne Hill — what to expect
The large Victorian and Edwardian houses in Herne Hill typically have generous rear gardens and ground floor plans that benefit significantly from rear extensions. Rear extensions opening up the kitchen into an open-plan kitchen-diner with garden access are the most common project type. Side return extensions are available on some end-of-terrace properties. Ground floor structural reconfigurations — removing dividing walls to create open-plan living — frequently accompany extension works.
Herne Hill property types
