About the Harleyford and Wittington Conservation Area
The Harleyford and Wittington Conservation Area covers about 110 hectares and was designated by Buckinghamshire Council in 1992. Inside the boundary are 16 listed buildings (1 Grade I, 1 Grade II*, 14 Grade II). The most significant is Harleyford Manor, Grade I. 7 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.

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