About the Clapham Conservation Area
The Clapham Conservation Area covers about 82 hectares and was designated by London Borough of Lambeth in 1968. Inside the boundary are 83 listed buildings (8 Grade II*, 75 Grade II). The most significant is 12-21, Clapham Common North Side Sw4, Grade II*. 6 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. 242 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work.
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.
