About the Grand Union and Oxford Canals Conservation Area
The Grand Union and Oxford Canals Conservation Area covers about 177 hectares within West Northamptonshire Council’s area. Inside the boundary are 47 listed buildings (1 Grade II*, 46 Grade II). The most significant is Church of St Peter and St Paul, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
