About the Bledlow Conservation Area
The Bledlow Conservation Area covers about 13 hectares and was designated by Buckinghamshire Council in 1971. Inside the boundary are 19 listed buildings (1 Grade I, 1 Grade II*, 17 Grade II). The most significant is Church of the Holy Trinity, Grade I. 5 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work.
