About the HAM Conservation Area
The HAM Conservation Area covers about 18 hectares and was designated by Wiltshire Council in 1973. Inside the boundary are 12 listed buildings (1 Grade I, 2 Grade II*, 9 Grade II). The most significant is Church of All Saints, Grade I. 1 Article 4 direction over the area removes further householder rights, on top of the conservation area limits below.
