About the Alton Conservation Area
The Alton Conservation Area covers about 29 hectares and was designated by East Hampshire District Council in 1976. Inside the boundary are 92 listed buildings (1 Grade I, 2 Grade II*, 89 Grade II). The most significant is Parish Church of St Lawrence, Grade I. 44 Tree Preservation Order records overlap the area; every other tree here still needs six weeks’ notice before work. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
