About the Cranborne Conservation Area
The Cranborne Conservation Area covers about 25 hectares and was designated by Dorset Council in 1970. Inside the boundary are 25 listed buildings (2 Grade I, 3 Grade II*, 20 Grade II). The most significant is Church of St Mary and St Bartholomew, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
