About the Grafton Underwood Conservation Area
The Grafton Underwood Conservation Area covers about 35 hectares and was designated by North Northamptonshire Council in 1977. Inside the boundary are 27 listed buildings (1 Grade I, 26 Grade II). The most significant is Church of St James, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
