About the Blyth Heritage Conservation Area
The Blyth Heritage Conservation Area covers about 3.5 hectares and was designated by Northumberland County Council in 1979. Inside the boundary are 12 listed buildings (1 Grade II*, 11 Grade II). The most significant is Church of St Cuthbert, Grade II*. 8 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. Part of the area lies in flood zone 2, so an extension may need a flood risk assessment.

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