About the Warmwell Conservation Area 1 Conservation Area
The Warmwell Conservation Area 1 Conservation Area covers about 7.4 hectares and was designated by Dorset Council in 1990. Inside the boundary are 8 listed buildings (1 Grade I, 1 Grade II*, 6 Grade II). The most significant is Warmwell House, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
