Detached Garage Planning Permission - Wales
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.
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.
