Do I need Planning Approval for a detached garage in Wales

Detached Garage Planning Permission - Wales


Do I need Planning permission or Building Control approvals?

To help you understand these issues we detail below some of the "conditions" attached to planning permission and Building Regulations. (These apply to Wales only) England, Scotland, Northern Ireland and Ireland regulations are quite different - You should in all instances take local advice.

 

Do I need permission for a Detached Garage?

You will need to apply for planning permission if any of the following cases apply on the land around your house.

  • You want to put up a building or structure which would be nearer to any highway than the nearest part of the "original house", unless there would be at least 20 metres between the new building and any highway. The term "highway" includes public roads, footpaths, bridleways and byways.
  • More than half the area of land around the "original house" would be covered by additions or other buildings.
  • The building or structure is not to be used for domestic purposes and is to be used instead, for example, for parking a commercial vehicle, running a business or for storing goods in connection with a business.
  • You want to put up a building or structure which is more than 3 metres high, or more than 4 metres high if it has a ridged roof. (Measure from the highest ground next to it.)
  • If your house is a listed building, or you live in a Conservation Area, a National Park, or an Area of Outstanding Natural Beauty, and you want to put up a building or structure with a volume of more than 10 cubic metres.

The words "original house" have a particular meaning.

The term "original house" means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

 

Note: If your new building would have a volume over 10 cubic metres, and come within 5 metres of the house, it would be treated as an extension and would count against your overall volume entitlement.

 

 

If the work you are carrying out involves making a new access, or the alteration of an existing access to a trunk or classified road, you will need planning permission, not only for the access but also for the development.
