About the Sleaford Conservation Area
The Sleaford Conservation Area covers about 46 hectares and was designated by North Kesteven District Council in 1973. Inside the boundary are 142 listed buildings (1 Grade I, 4 Grade II*, 137 Grade II). The most significant is Parish Church of St Denys, 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.
