Flood zones apply along the Thames, restricting certain outbuilding classes near the river. The borough borders Richmond Park, a National Nature Reserve with additional controls near its edges.

In conservation areas, the same PD rules apply to porches, but you should use materials sympathetic to the area character.
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.
Check if your property is in a conservation area or has other planning constraints.
