About the MINIONS Conservation Area
The MINIONS Conservation Area covers about 1,134 hectares and was designated by Cornwall Council in 1992. Inside the boundary are 13 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.
