About the Vernham Dean Conservation Area
The Vernham Dean Conservation Area covers about 5.0 hectares and was designated by Test Valley Borough Council in 1983. Inside the boundary are 22 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
