About the Sheerness : Royal Naval Dockyard and Bluetown Conservation Area
The Sheerness : Royal Naval Dockyard and Bluetown Conservation Area covers about 33 hectares and was designated by Swale Borough Council in 1972. Inside the boundary are 30 listed buildings (1 Grade I, 7 Grade II*, 22 Grade II). The most significant is Shed Number 78 the Boat Store Building Number 78, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
