About the Owen's Southsea Conservation Area
The Owen's Southsea Conservation Area covers about 35 hectares and was designated by Portsmouth City Council in 1969. Inside the boundary are 49 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
