About the Ottery St Mary Conservation Area
The Ottery St Mary Conservation Area covers about 52 hectares and was designated by East Devon District Council in 1973. Inside the boundary are 47 listed buildings (1 Grade I, 3 Grade II*, 43 Grade II). The most significant is Church of St Mary, Grade I. Part of the area lies in flood zone 2, so an extension may need a flood risk assessment.
