About the Lower Sunbury Conservation Area
The Lower Sunbury Conservation Area covers about 37 hectares within Spelthorne Borough Council’s area. Inside the boundary are 53 listed buildings (2 Grade II*, 51 Grade II). The most significant is Church of St Mary the Virgin, Grade II*. 62 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.
