On the hunt for garden room ideas to help maximise your home’s outdoor area? Garden rooms can add a characterful addition to your home and its surroundings whilst offering multiple uses and functions.

Perhaps you may have started working from home post-pandemic and discovered your lack of quiet space, or maybe you’re in need of another bedroom to accommodate guests and building a house extension isn’t an option.

Garden rooms can offer you this space should you need it, and help you maximise your plot in a creative and interesting way. It’ll also add to your house’s value should you ever decide to sell as they make an attractive addition to a property’s full package.

From beautiful oak frame structures to sleek contemporary studios, this hand-picked selection of garden room ideas demonstrates how a well-designed outbuilding can make the most of your space.

2. Oak Frame Outbuilding with Stylish Veranda

This summerhouse by Carpenter Oak takes outbuilding luxury to the next level. Fitted with a kitchen and toilet, it’s an ideal space to socialise and entertain. The oak post and beam structure brings extra character and warmth to the design.

3. Bespoke Garden Office with Pivot Door

4. Timber-Clad Garden Room Idea

Essentially a concrete box with a blackened timber lid, this design by Eckford Chong was inspired by the cherry tree that it’s positioned beneath.

Stained larch cladding creates a subtle external appearance, while a large rooflight fills the space with natural light.

CLOSER LOOK Do you need planning permission to build a garden room?

Most garden rooms won’t require planning consent, as provided they’re at the rear of the property they’ll generally fall under permitted development (PD) rights. “Projects that can be achieved under PD will broadly speaking be a single-storey building with a maximum roof ridge height of 4m,” says Richard Keys, founding director of ByOthers Studio.

The limits are stricter if the garden room is going to be close to a boundary. You’ll also need to consider the use of the building; anything that’s going to act as primary accommodation will require further applications, while features such as verandas don’t count as permitted development.

If you’re planning to use your garden room  as a primary workplace for a business then you’ll need to consult your local planning authority, too. Holding meetings, having staff come and go, and using the garden office for frequent activity that may cause disturbance through noise or excessive parking will make an impact on whether or not your garden office will receive planning consent.

PD rights are restricted for listed properties and those in designated areas, such as national parks and areas of outstanding natural beauty. If you’re able to build your garden office under permitted development, it’ll be wise to consider a Lawful Development Certificate as this proves the work was permitted and will come in handy should you choose to sell your home.

14. Contemporary Garden Building

Designed by Fab Architects, structural insulated panels (SIPs) were chosen as the construction method for this quirky outbuilding complete with statement arched window. Due to the lightweight nature of the structure, it sits atop ground screws rather than conventional concrete foundations.
