Planning Permission for a Loft Conversion

When it comes to converting a loft, you may need planning permission. Let’s take a look at the specific requirements and what the process entails.

If you plan to alter or extend your roof space, you need planning permission. This is especially true if it exceeds certain conditions. Although a loft conversion is allowed, you need to make sure that you follow these conditions:

  • Expand to a maximum of 40 cubic metres
  • Expand to a maximum of 50 cubic metres for detached houses
  • No extension beyond the existing roof slope
  • no extension is higher than the roof of the house
  • materials have to have the same appearance
  • no raised platforms or balconies
  • the roof enlargements should not overhang the wall’s outer face

It is also important to note that in previous editions all changes have to be included in the list above. As a homeowner, you may not have made any changes the previous owners may have. These requirements listed above apply to houses. There are a different set of requirements for flats and other buildings.

If you do any work or build a loft you need to consider whether you’re influencing any protected species. For example, if there are bats in the building you may need to get a professional survey. In some cases, a license will be needed.

There are certain regulations that are required when you want to convert a loft into a liveable area. Many things will be considered, including the structural strength of your floor. You should also consider the stability of the structure and whether there is safe escape from a fire.
