About the CLAY HILL Conservation Area
The CLAY HILL Conservation Area covers about 52 hectares and was designated by London Borough of Enfield in 1983. Inside the boundary are 8 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.

These overlap the conservation area. Householder directions remove more of the rights above; change-of-use ones don’t affect extending a house.
