About the Dewlish Conservation Area
The Dewlish Conservation Area covers about 14 hectares and was designated by Dorset Council in 1990. Inside the boundary are 8 listed buildings (2 Grade II*, 6 Grade II). The most significant is Church of All Saints, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
