About the Seaford (Town Centre) Conservation Area
The Seaford (Town Centre) Conservation Area covers about 8.9 hectares and was designated by Lewes District Council in 1968. Inside the boundary are 31 listed buildings (1 Grade I, 30 Grade II). The most significant is The Parish Church of St Leonard, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
