About the Castle Road Conservation Area
The Castle Road Conservation Area covers about 9.1 hectares and was designated by Portsmouth City Council in 1969. 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.
