About the Chilbolton Conservation Area
The Chilbolton Conservation Area covers about 17 hectares and was designated by Test Valley Borough Council in 1984. Inside the boundary are 32 listed buildings (1 Grade I, 1 Grade II*, 30 Grade II). The most significant is Church of St. Mary the Less, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
