About the BURNHAM OVERY the MILLS Conservation Area
The BURNHAM OVERY the MILLS Conservation Area covers about 3.6 hectares and was designated by Borough Council of King's Lynn and West Norfolk in 1986. Inside the boundary are 3 listed buildings (1 Grade II*, 2 Grade II). The most significant is Windmill, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
