What to know before building in Greenwich
Georgian and Victorian houses around Greenwich and Blackheath, and interwar semis and terraces across Eltham and Plumstead. Rear extensions and lofts on the terraces, basement and period-house refurbishments nearer the park, and wraparounds in Eltham.
Maritime Greenwich is a World Heritage Site and Blackheath is a conservation area, so design quality and materials matter to the council. We check your exact address with the Royal Borough of Greenwich records before we draw anything, and price the whole job — design, approvals and build — in one estimate.
