About the Chelsea Park/Carlyle Conservation Area
The Chelsea Park/Carlyle Conservation Area covers about 23 hectares and was designated by Royal Borough of Kensington and Chelsea in 1971. Inside the boundary are 29 listed buildings (3 Grade II*, 26 Grade II). The most significant is 40, Chelsea Square Sw3, Grade II*. 8 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. 5 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work.
