House Extensions in Putney
Putney is one of South West London's most established and affluent residential neighbourhoods — excellent transport links, proximity to the Thames, large Victorian and Edwardian houses, and an active renovation market. RCB Design & Build delivers extensions, loft conversions, and full refurbishments across SW15.
House Extensions in Putney — what to expect
Putney has a wide range of property types with good extension potential. Victorian terraces in SW15 suit rear ground floor extensions at 3–6m, typically to create open-plan kitchen-dining space. The wider Edwardian semis and detached houses have more flexibility — double-storey rear extensions, wrap-around extensions, and side extensions are all viable depending on the specific plot. Many properties near the river fall within conservation areas or have views that affect what planning will support.
Putney property types
Victorian and Edwardian terraced houses, inter-war semis, detached houses, period mansion blocks near the river. The property type affects which extensions approach works best — we'll advise from the first call.
