About the Courtfield Conservation Area

The most significant is 1-8, Collingham Gardens Sw5, Grade II*. 4 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.
