About the Headlam Conservation Area
The Headlam Conservation Area covers about 16 hectares and was designated by Durham County Council in 1984. Inside the boundary are 8 listed buildings (1 Grade II*, 7 Grade II). The most significant is Headlam Hall, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
