About the Royal Parks Conservation Area

The Royal Parks Conservation Area covers about 323 hectares and was designated by City of Westminster in 1990. Inside the boundary are 98 listed buildings (23 Grade I, 10 Grade II*, 65 Grade II). The most significant is Apsley House, Grade I. 3 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. 14 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.

What changes inside the conservation area

Conservation areas are “Article 2(3) land”. You keep most permitted development rights, but these are removed or tightened.

Limits for a semi-detached house under the GPDO 2015. An Article 4 direction can remove more.

Article 4 directions here

These overlap the conservation area. Householder directions remove more of the rights above; change-of-use ones don’t affect extending a house.
