About the Thorington Street Conservation Area
The Thorington Street Conservation Area covers about 14 hectares within Babergh District Council’s area. Inside the boundary are 17 listed buildings (1 Grade II*, 16 Grade II). The most significant is Thorington Hall, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
