About the Rickmansworth Town Centre Conservation Area
The Rickmansworth Town Centre Conservation Area covers about 28 hectares and was designated by Three Rivers District Council in 1973. Inside the boundary are 25 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
