About the Cockfield Conservation Area
The Cockfield Conservation Area covers about 326 hectares and was designated by Durham County Council in 2001. Inside the boundary are 10 listed buildings (1 Grade II*, 9 Grade II). The most significant is Church of St. Mary, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
