If your confused about what your permitted development rights are and whether or not you need planning permission for your garden room, please take the time to read this handy guide to permitted development and what that means for you and your build.
Permitted Development vs Planning Permission.
Most garden rooms don't require planning permission. They are classed as outbuildings, so you're allowed to build one as long as you comply with certain rules. That’s as long as you have permitted development rights at your home or the area you live in. You might not have permitted development rights if: your home is a listed building your home is in a designated area (eg a National Park, area of outstanding natural beauty (AONB), conservation area or World Heritage Site) Check with your local planning office if you’re not sure. Flats and maisonettes don’t have permitted development rights. The rules are the same whether you live in England, Northern Ireland, Scotland or Wales.
