About the Highgate Conservation Area
The Highgate Conservation Area covers about 226 hectares and was designated by London Borough of Haringey in 1967. Inside the boundary are 103 listed buildings (4 Grade I, 4 Grade II*, 95 Grade II). The most significant is Cromwell House, Grade I. 1 Article 4 direction over the area removes further householder rights, on top of the conservation area limits below. 7 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.
