About the Trafalgar Avenue Conservation Area
The Trafalgar Avenue Conservation Area covers about 1.8 hectares within London Borough of Southwark’s area. Inside the boundary are 9 listed buildings, all Grade II. 4 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
