About the HELFORD Conservation Area
The HELFORD Conservation Area covers about 6.1 hectares and was designated by Cornwall Council in 1969. Inside the boundary are 25 listed buildings, all Grade II. 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.
