A garden room extension is a standalone structure that's typically built in the garden, often connected to the main house via a door or a set of steps. It can be used for a variety of purposes, from a home office to a gym, a guest room, or even a relaxation space. Garden rooms are usually built using modern materials like UPVC, composite, or timber, and they often come with features like double glazing, insulation, and heating to ensure year-round comfort.

One of the key aspects of a garden room extension is that it's usually a permanent structure. Unlike garden sheds or summer houses, which are often temporary and not designed for year-round use, garden rooms are built to last and can add value to your home. However, it's important to note that while they're typically considered permanent, they're often not as complex or expensive to build as a traditional home extension.
