About the Winterbourne Steepleton Conservation Area 1 Conservation Area
The Winterbourne Steepleton Conservation Area 1 Conservation Area covers about 6.6 hectares and was designated by Dorset Council in 1990. Inside the boundary are 14 listed buildings (1 Grade I, 2 Grade II*, 11 Grade II). The most significant is Church of St Michael, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
