About the Sudbury Conservation Area
The Sudbury Conservation Area covers about 67 hectares and was designated by Babergh District Council in 1973. Inside the boundary are 229 listed buildings (6 Grade I, 7 Grade II*, 216 Grade II). The most significant is Church of All Saints, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
What changes inside the conservation area
Conservation areas are “Article 2(3) land”. You keep most permitted development rights, but these are removed or tightened.
