House Extensions in Woolwich
Woolwich has transformed significantly since the Crossrail/Elizabeth line opened at Woolwich station. Investor activity and owner-occupier renovation work have accelerated across SE18 as a result.
rcbGroup projectHouse Extensions in Woolwich — what to expect
Woolwich's Victorian terrace stock generates consistent rear extension work — typically 3–6m kitchen extensions with flat roofs and roof lights. The denser terraces in the streets around Plumstead Road have tighter rear gardens but the extension potential is still real. Side return extensions on end-of-terrace properties are popular.
Woolwich property types
Victorian and Edwardian terraces, post-war council housing. The property type affects which extension approach works best — we'll advise from the first call.
