About the Summerhouse Conservation Area
The Summerhouse Conservation Area covers about 19 hectares and was designated by Darlington Borough Council in 1978. Inside the boundary are 13 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
