About the Southwick Conservation Area
The Southwick Conservation Area covers about 21 hectares and was designated by Adur District Council in 1976. Inside the boundary are 18 listed buildings (2 Grade II*, 16 Grade II). The most significant is Church of St Michael, Grade II*. 2 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. 103 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.
