Does My Garden Room Need Planning Permission?
What You Need To Know.
When planning your Garden Room, planning permission, and planning regulations, are often one of the first things you think about. In this article we want to help answer the question; “Do I need planning permission for a garden room?”.
Planning a Self-Build Garden Room to maximise your garden space is an exciting project. So, we want to help ease your planning permission concerns. Here, you’ll find everything you need to know about garden room planning permission regulations and considerations.
Understanding Planning Regulations for Garden Buildings
Great News! In most cases, garden buildings do not require planning permission if they adhere to specific building regulations.
You usually don’t need planning permission if:
- Your garden building is under 2.5 metres tall, located at the rear of the property, and not intended for overnight accommodation.
- Your Garden Room doesn’t cover more than 50% of the land around the original house, considering any previous extensions or outbuildings constructed after 1948.
- If the garden room’s floor area is less than 30 square metres and it contains no sleeping accommodation. For studios with a floor area between 15 and 30 square metres, building regulations approval is not usually required, provided the studio is at least one metre from any boundary and contains no sleeping accommodation.
Most Penthaus Studios do not require planning permission or building regulations approval because they are designed to comply with permitted development guidelines.
Why Are Garden Rooms Usually Exempt?
Garden rooms are classified as “outbuildings” and can be built without planning permission if they comply with permitted development guidelines. These guidelines ensure that the structure does not negatively impact the surrounding environment or your neighbours.
How Can I Check if I Need Planning Permission?
Whether you need planning permission depends on the specific permitted development rights for your property and the area you live in. To be certain, the best place to start is checking your local authorities’ website, which will then direct you on the best way to check. You can also get in touch with our lovely customer service team who can help provide information you need for your application.

Garden Room Development Guidelines
What To Consider:
Understanding development guidelines can be complex! Below we have expanded on the main guidelines to consider.
Height and Area Restrictions
- Your garden room must be a single-story structure with a maximum roof height of 2.5 metres from ground level.
- Permitted development guidelines restrict you from building on more than 50% of the land around the original house, which includes any previous extensions or outbuildings built after 1948.
Location Considerations
- Planning permission is required if the garden room is located in front of the principal elevation of the house or to the side.
- It should not be built closer to a public road or footpath than the main house.
- Garden rooms can be used for daily activities but are not permitted if you will be predominantly using the building for overnight accommodation, or self-contained living accommodation.
Exterior Finishes and Designated Land
- Permitted development guidelines prohibit verandas, or balconies. Any decking or platform should not exceed 0.3 metres in height to maintain privacy and avoid obstructing views.
- Permitted development may not apply in areas classified as designated land, such as national parks, the Broads, Areas of Outstanding Natural Beauty, and World Heritage Sites. In these areas, garden rooms more than 20 metres from the house must not exceed 10 square metres.
Do Planning Regulations Apply to Your Home?
- Permitted development rights do not apply to flats, maisonettes, or other buildings. Only houses are eligible.
- Additionally, if your home is a listed building or in a designated area, your development rights may be restricted. Designated areas including national parks, the Broads, Areas of Outstanding Natural Beauty, conservation areas, and World Heritage Sites. There are some exceptions to this, so in these cases we recommend checking with your local planning authority.
