About the Diss Conservation Area

The Diss Conservation Area covers about 54 hectares and was designated by South Norfolk District Council in 1974. Inside the boundary are 149 listed buildings (1 Grade I, 2 Grade II*, 146 Grade II). The most significant is Church of St Mary, Grade I. 1 Article 4 direction over the area removes further householder rights, on top of the conservation area limits below. 32 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.

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.

Limits for a semi-detached house under the GPDO 2015. An Article 4 direction can remove more.

Article 4 directions here

These overlap the conservation area. Householder directions remove more of the rights above; change-of-use ones don’t affect extending a house.
