14 Glorious Garden Rooms and Outbuildings

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.

Garden rooms can offer you this space should you need it, and help you maximise the plot of your home 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.

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

1. Multi-Purpose Timber Frame Statement

This outbuilding serves multiple uses, working as as a pottery studio, home office and entertaining space.

The bespoke timber frame structure is lined both inside and out in birchwood ply whilst the exterior has been painted black to create a design statement.

Overhead glazing and a span of bifold doors ensure the interior is flooded with light all year round. This garden room was designed by Grey Griffiths Architects.

2. Striking Oak Frame Outbuilding

This oak frame detached garden room was designed and built by Oakwrights.

The bays of the oak skeleton help divide the space into various zones, including a kitchenette, study and living area.

The vaulted ceiling provides a clean backdrop for the exposed rafters and trusses, making them the main focal point of this striking outbuilding.

Inside, bespoke built-in plywood joinery has been incorporated to maximise every nook and cranny.

The corner window makes a sleek statement to the build whilst inviting plenty of sunlight in at multiple angles, ensuring the space doesn’t ever feel dark or cramped.

4. Industrial Inspired Studio

This timber frame garden studio has replaced an old garden shed.

Spanning the full width of the garden, the structure is clad in corrugated metal that will weather beautifully over time.

DO I NEED PERMISSION?

There’s plenty of reasons why erecting a standalone garden room will enhance your property.

However, before charging ahead with your project, it’s important to check what permissions you’ll need to get in place first.

Providing your garden outbuilding falls into specific criteria in terms of its size, height and location within your outdoor space, it should be covered by Permitted Development.

However, formal consent will be required if your property is situated within a designated zone, such as an area of outstanding natural beauty (AONB) or conservation area. If you plan on incorporating any standout design details or exterior finishes, it’s always worth checking with the local council first or obtaining a certificate of lawful development for peace of mind.

Typically, garden rooms measuring up to 30m2 are exempt from Building Regulations – unless you have plans to use your new space as sleeping accommodation separate from the main house.

5. Brick and Block Guest Suite

Planning permission was required for this garden studio, as the property is in a conservation area.

Constructed by Parkwood Builders, the brick and block outbuilding at the end of this garden provides supplementary accommodation for when guests come to stay.

It features a green roof, which helps it blend into the rest of the garden when viewed from the upper levels of the house.

6. Oak Frame Garden Room Retreat

Designed as a living area and artist’s studio, this oak frame outbuilding serves as a tranquil retreat away from the main house, surrounded by long grasses and trees.

Featuring clay roof tiles and redwood feather edge weatherboarding, the structure nestles beautifully into its scenic rural setting.

Floor-to-ceiling fixed windows have been positioned next to a glazed French door to establish a wall of glass, with a glazed gable above for extra wow factor. This project was delivered by oak specialists Border Oak.

7. Contemporary Construction

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.

Planning permission was required for this project, but was a necessary space for the family as it now functions as a home office, rehearsal space and entertaining area.

8. Reclaimed Wash House

Bricks from the original building were salvaged and reused to form the new structure, which makes up an office/reading room and a WC/shower. The project was completed under permitted development.
