About the Caston Conservation Area
The Caston Conservation Area covers about 19 hectares and was designated by Breckland District Council in 1976. Inside the boundary are 12 listed buildings (1 Grade I, 11 Grade II). The most significant is Church of Holy Cross, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
