About the Copley Conservation Area
The Copley Conservation Area covers about 2.2 hectares and was designated by Calderdale Metropolitan Borough Council in 1983. Inside the boundary are 8 listed buildings (1 Grade II*, 7 Grade II). The most significant is Church of St Stephen, Grade II*. 35 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
