About the Henley, Main Conservation Area

The Henley, Main Conservation Area covers about 99 hectares and was designated by Buckinghamshire Council in 1969. Inside the boundary are 360 listed buildings (2 Grade I, 18 Grade II*, 340 Grade II). The most significant is Chantry House, Grade I. 5 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.
