Do I need planning permission
for a garden room?

Most garden rooms don’t need planning permission as they are considered permitted development. 


If your garden room meets the below criteria it is unlikely you will need planning permission. However, you should always check with your local planning authority before going ahead with any building work.

  • The building is less than 2m from the boundary, with a maximum overall height of 2.5m from the existing ground level.

  • If the building is more than 2m from the boundary, the building can have a maximum eaves height of 2.5m and an overall height of 4m for a pitched roof and a maximum of 3m for a flat roof.

  • The building does not take up more than 50% of the area of land around the original house and other out buildings.

  • The garden room measures 30 msq internally or less. For buildings bigger than 30 msq you will need to apply for Building Regulations.

If you do need planning permission for your garden room this is normally a straightforward process and we are happy to help and advise you.

Please be aware it is the homeowner’s responsibility to check if planning permission is needed, and if required, permission should be granted before any building work begins.
