About the Tiffield Conservation Area
The Tiffield Conservation Area covers about 5.1 hectares and was designated by West Northamptonshire Council in 1991. Inside the boundary are 11 listed buildings (1 Grade II*, 10 Grade II). The most significant is Church of St John the Baptist, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
