One of the most common questions we get asked is whether a garden room needs planning permission. The good news is that most garden buildings fall under permitted development rights, meaning you won't need to apply for planning permission at all.
What Are Permitted Development Rights?
Permitted development rights allow homeowners to make certain changes to their property without needing formal planning permission. Garden rooms typically fall under these rights as long as they meet specific criteria.
The Key Requirements
To qualify under permitted development, your garden room must:
- Be single storey with a maximum eaves height of 2.5 metres
- Have a maximum overall height of 4 metres (dual pitched roof) or 3 metres for any other roof type
- Not exceed 50% of your total garden area
- Not be positioned forward of the principal elevation
- Not be used as self-contained living accommodation
When You Will Need Planning Permission
You'll need to apply for planning permission if:
- Your property is a listed building
- You live in a conservation area, National Park, or Area of Outstanding Natural Beauty
- The building will be used as separate living accommodation
- The dimensions exceed permitted development limits
Building Regulations
Even if you don't need planning permission, building regulations may still apply, particularly for garden rooms with plumbing or electrical installations. At LouMil, we handle all of this for you and ensure full compliance.
