Loft Conversions & Planning permission

With effect from 1 October 2008, you don’t require planning permission to construct a Loft Conversion on your property subject to conditions.
Providing the loft is not larger than 40 cubic metres for terraced houses and 50 cubic metres for detached and semi-detached houses, you shouldn’t have any problems.
There are other conditions which are listed on Local government websites, but we think these are easier to conform with.
