About the Marcham Conservation Area
The Marcham Conservation Area covers about 11 hectares and was designated by Vale of White Horse District Council in 1969. Inside the boundary are 22 listed buildings (1 Grade II*, 21 Grade II). The most significant is Church of All Saints, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
