About the Wonston Conservation Area
The Wonston Conservation Area covers about 22 hectares and was designated by Winchester City Council in 1984. Inside the boundary are 8 listed buildings (2 Grade II*, 6 Grade II). The most significant is Church of the Holy Trinity, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
