About the Richmond Riverside Conservation Area
The Richmond Riverside Conservation Area covers about 22 hectares and was designated by London Borough of Richmond upon Thames in 2005. Inside the boundary are 18 listed buildings (2 Grade I, 2 Grade II*, 14 Grade II). The most significant is Asgill House, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
