Greenwich has a UNESCO World Heritage Site at Maritime Greenwich, which triggers Article 2(3) designated land rules — standard permitted development dimension limits are effectively halved near the WHS. Conservation areas include Blackheath, Charlton Village, and Eltham. Listed buildings are particularly concentrated around the Royal Naval College and Greenwich Park. The Thames frontage adds flood zone considerations for properties along the river.

Get personalised guidanceConservation Areas & Listed Buildings
In conservation areas, changing window materials (e.g. timber to UPVC) or styles may need planning permission. Listed buildings always need Listed Building Consent for any window or door changes.
Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.
Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.
