Gable Roofs for Garden Rooms and Annexes
A Gable Roof is a popular upgrade to our standard flat roof garden rooms.
With its pitched structure and vaulted ceiling, a gable roof instantly transforms the look and feel of your space—adding more vertical height, visual interest, and a brighter, airier interior.
At Composite Garden Buildings, we offer gable roof options for many of our garden rooms, perfect for anyone looking for something a little more spacious and architectural.
Vaulted Ceilings for Extra Space
Unlike flat roofs, gable roofs create a vaulted ceiling which adds significant vertical height inside your garden room. This extra headroom is particularly useful if you're using your garden building for activities that require more space—like installing a golf simulator, home cinema or creating a home gym.
A taller ceiling also improves airflow and makes the space feel less enclosed, especially in compact gardens.
Ideal for Golf Simulators and Specialist Use
One of the most common reasons customers choose a gable roof is for golf simulators. The extra height is essential for safely swinging a club indoors. Whether you’re an amateur golfer or a dedicated pro, this upgrade allows you to practise in comfort all year round.
We can customise your garden room around your golf equipment, with the gable roof creating the perfect indoor swing zone.
Glass Gable Option for More Natural Light
To make the most of the dual pitched design, we can fit your gable roof with a Glass Gable End. This elegant feature fills the interior with daylight, reduces the need for artificial lighting, and gives the room a fresh, open feel.
It’s especially effective for home offices, studios, or garden lounges—helping connect the indoors with the outdoors in a natural and modern way.
Timeless Style That Stands Out
A gable roof doesn't just make the interior more practical—it improves the whole aesthetic of your garden room from the outside. The pitched profile gives a more ‘house-like’ feel and works beautifully in both traditional and contemporary garden settings.
Whether you're aiming for a classic cabin look or something sleek and modern, a gable roof helps your garden building blend in—or stand out.
Why Choose a Gable Roof Garden Room?
A gable roof garden room gives you more than just extra headroom—it adds style, function, and flexibility to your space
