In most cases, you won’t need planning permission for a garden room in the UK if it meets certain criteria:
- Size: The building must be smaller than 15 square meters.
- Height: The building must be lower than 2.5 meters high.
- Distance from boundaries: The building must be at least 2 meters away from any boundary.
However, there are some exceptions:
- Listed buildings: If your property is a listed building or in a conservation area, you may need planning permission, even for smaller structures.
- Specific local planning policies: Local planning authorities may have specific rules that could affect your plans.
It’s always best to check with your local planning authority to be sure. They can provide specific guidance and advice on your particular situation.
