About the Lower Harlestone Conservation Area
The Lower Harlestone Conservation Area covers about 17 hectares within West Northamptonshire Council’s area. Inside the boundary are 23 listed buildings (1 Grade I, 1 Grade II*, 21 Grade II). The most significant is Church of St Andrew, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
