Garden Room Planning Permission

Garden rooms are one of the most popular ways to add usable space at home. Whether you want a garden office, home gym, studio, games room or relaxation space, a timber garden room can be a practical and attractive solution.

In many cases, garden rooms can be installed without a full planning application, provided they meet permitted development rules. However, this depends on the size, height, position and intended use of the building.

This guide explains when a garden room may be permitted development, when planning permission may be needed, and what to consider before choosing your cabin.

When a Garden Room May Not Need Planning Permission

A garden room may not need planning permission if it is used for an incidental domestic purpose and meets the relevant permitted development conditions.

Common permitted uses may include a home office, gym, art studio, music room, hobby room, reading room, garden bar, summerhouse or storage space. The building must usually be single storey and positioned within the correct part of the garden.

If the garden room is used only by the household and does not include sleeping accommodation, it is more likely to fall within permitted development.

Garden Offices and Working from Home

A garden office used for normal home working may often be acceptable as an incidental use. For example, someone working remotely at a desk in their own garden room is usually very different from running a business premises with staff, customers, deliveries or regular visitors.

Planning permission may be more likely if the use causes noise, parking issues, increased traffic, signage, customer visits or a noticeable change in the character of the property.

If your garden office will be used for business activity beyond normal home working, check with your local planning authority.

Toilets, Kitchens and Sleeping Accommodation

Adding a toilet, shower, kitchenette or sleeping area can make a garden room more complicated from a planning perspective. These features may suggest that the building could be used as accommodation rather than simply a garden room.

They can also bring building regulations, drainage, plumbing and electrical considerations into the project.

If your garden room includes facilities that could allow someone to live or sleep there independently, it is best to get advice before installing it.
