About the Wandle Valley Conservation Area
The Wandle Valley Conservation Area covers about 100 hectares and was designated by London Borough of Merton in 1990. Inside the boundary are 30 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
