About the Longstock Conservation Area
The Longstock Conservation Area covers about 32 hectares and was designated by Test Valley Borough Council in 1989. Inside the boundary are 34 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
