Do You Need Planning Permission for a Combination Garden Room?
In most cases, garden rooms fall under permitted development rights, meaning you won’t usually need planning consent. However, factors such as overall size, how close the building is to boundaries, or the way you plan to use the space can influence whether approval is required.
As a general rule, if your structure is under 2.5 m in height and positioned within your back garden, it will typically meet permitted development guidelines. Larger footprints, business-use studios or buildings installed in conservation areas may still require planning checks, so it’s worth confirming the details with your local authority.
We’ve put together a clear guide outlining the key requirements, exemptions and how to ensure your project stays compliant.
