House Extensions in Camberwell
Camberwell is a dense, architecturally rich South London neighbourhood in SE5 — Georgian townhouses, Victorian terraces, and period buildings in various stages of improvement. With strong transport links and proximity to central London, Camberwell has become a significant renovation market. RCB Design & Build delivers extensions, loft conversions, and refurbishments including HMO conversions across SE5.
House Extensions in Camberwell — what to expect
Camberwell's Victorian and Georgian terraces typically have moderate rear garden depths. Ground floor rear extensions at 3–5m are the most common type, creating open-plan kitchen-diner space. Side return extensions suit end-of-terrace properties in the wider residential streets. Some Georgian properties near Camberwell Green sit within conservation areas requiring additional planning attention.
Camberwell property types
Georgian and Victorian terraced houses, converted Victorian flats, HMO properties, commercial conversions. The property type affects which extensions approach works best — we'll advise from the first call.
