About the Maidstone, Holy Trinity Church Conservation Area
The Maidstone, Holy Trinity Church Conservation Area covers about 5.9 hectares and was designated by Maidstone Borough Council in 1977. Inside the boundary are 14 listed buildings, all Grade II. 2 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. 48 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work.
