About the Lakenheath Conservation Area
The Lakenheath Conservation Area covers about 25 hectares and was designated by West Suffolk Council in 1980. Inside the boundary are 8 listed buildings (1 Grade I, 7 Grade II). The most significant is Church of St Mary, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
