About the Thomas A'Becket and High Street Conservation Area
The Thomas A'Becket and High Street Conservation Area covers about 8.5 hectares within London Borough of Southwark’s area. Inside the boundary are 5 listed buildings, all Grade II. 14 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.
What changes inside the conservation area
Conservation areas are “Article 2(3) land”. You keep most permitted development rights, but these are removed or tightened.

Article 4 directions here
These overlap the conservation area. Householder directions remove more of the rights above; change-of-use ones don’t affect extending a house.
