About the TRURO Conservation Area
The TRURO Conservation Area covers about 97 hectares and was designated by Cornwall Council in 1969. Inside the boundary are 272 listed buildings (1 Grade I, 7 Grade II*, 264 Grade II). The most significant is Truro Cathedral, Grade I. Part of the area lies in flood zone 2, 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.
