About the Brompton Conservation Area
The Brompton Conservation Area covers about 16 hectares and was designated by North Yorkshire Council in 1987. Inside the boundary are 10 listed buildings (1 Grade I, 9 Grade II). The most significant is Church of St Thomas, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
