More Space Without the Hassle of an Extension

A garden room gives you a genuine extra room without the disruption, planning headaches or cost of a full house extension. Whether you need a quiet home office, a fitness space or somewhere to unwind, it’s usable square footage added to your property without moving a wall.

In most cases, garden rooms fall under permitted development rights, meaning no formal planning permission is required. Malbern’s team will guide you through everything from first design conversation to final installation – straightforward, stress-free and built right first time.

Designed Around You

Every garden room we build is tailored to suit the way you live. Choose from a range of windows and doors to create a space that works for you, whether that’s bifolds for wide open views, French doors for a touch of classic style, or a mix of windows to make the most of the natural light.

Speak to our friendly team today to begin planning your dream garden room extension.
