About the Great Horwood Conservation Area
The Great Horwood Conservation Area covers about 20 hectares and was designated by Buckinghamshire Council in 2013. Inside the boundary are 40 listed buildings (1 Grade II*, 39 Grade II). The most significant is Church of St James, Grade II*. 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.
