About the RIVERSIDE SOUTH Conservation Area
The RIVERSIDE SOUTH Conservation Area covers about 23 hectares and was designated by Royal Borough of Kingston upon Thames in 2003. Inside the boundary are 12 listed buildings (1 Grade II*, 11 Grade II). The most significant is Roman Catholic Church of St Raphael, Grade II*. 1 Article 4 direction over the area removes further householder rights, on top of the conservation area limits below. 58 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
