About the Whaddon Conservation Area
The Whaddon Conservation Area covers about 20 hectares and was designated by Buckinghamshire Council in 1990. Inside the boundary are 13 listed buildings (1 Grade I, 12 Grade II). The most significant is Church of St Mary, Grade I. 8 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work.
