House 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 extensions approach works best — we'll advise from the first call.
