About the Compton Martin Conservation Area
The Compton Martin Conservation Area covers about 11 hectares and was designated by Bath and North East Somerset Council in 1993. Inside the boundary are 8 listed buildings (1 Grade I, 7 Grade II). The most significant is Church of St Michael and All Angels, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
