What the data says about planning in Greenwich
the Royal Borough of Greenwich granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The Maritime Greenwich World Heritage Site and its buffer zone add height and setting tests near the town centre, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which the Royal Borough of Greenwich needs a full application. Greenwich carries at least one Article 4 direction, and conservation areas including West Greenwich, Blackheath Park and Ashburnham Triangle remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Greenwich is determined against an 8-week statutory target.
Greenwich (Georgian and early-Victorian terraces inside the West Greenwich conservation area), Blackheath (villas and terraces around the Cator Estate and Blackheath Park), Westcombe Park (Edwardian and Victorian villas climbing the hill above the river), Charlton (the older cottages and interwar streets around Charlton Village), Eltham (interwar semis including the Well Hall Progress Estate) and Woolwich (denser Victorian terraces amid riverside regeneration) — these are the Greenwich pockets our drawings cover most. Heritage designations here include West Greenwich, Blackheath Park, Ashburnham Triangle, Westcombe Park and Charlton Village. the Royal Borough of Greenwich weighs each proposal against the Royal Greenwich Local Plan: Core Strategy with Detailed Policies and the borough's residential extensions design guidance, where protected Thames-side views shape what roof additions are acceptable on the borough's northern edge. On roofs the borough is parapet and butterfly roofs on the Georgian terraces and pitched and hipped roofs on the villas, over Georgian and early-Victorian terraces, Victorian and Edwardian villas and riverside and interwar housing.
