About the Cobham The Tilt Conservation Area
The Cobham The Tilt Conservation Area covers about 11 hectares and was designated by Elmbridge Borough Council in 1979. Inside the boundary are 4 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
