About the Charlton Marshall Conservation Area
The Charlton Marshall Conservation Area covers about 14 hectares and was designated by Dorset Council in 1995. Inside the boundary are 12 listed buildings (1 Grade I, 11 Grade II). The most significant is Church of St Mary, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
