About the Hempnall Conservation Area
The Hempnall Conservation Area covers about 21 hectares and was designated by South Norfolk District Council in 1994. Inside the boundary are 24 listed buildings (1 Grade I, 23 Grade II). The most significant is Church of St Margaret, Grade I. 14 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
