What Is a Garden Room?
It's one of the questions we're asked most often, and it's a good one. A garden room extension is a semi-glazed building with a lantern or some part of the roof is tiled or solid in part, as distinct from the fully glazed roof of a conservatory. That distinction matters more than you might think.
A lantern or tiled roof means better insulation, less glare, and a space that feels like a proper room, not a greenhouse. Combined with generous glazing, full-height timber doors and James Alexander's signature roofline, the result is a building that's as beautiful to look at as it is to live in.

Our hardwood garden rooms are designed to combine timeless craftsmanship, natural light and practical everyday living. Below, we answer some of the most common questions homeowners ask when considering a bespoke hardwood garden room.
-
The cost of a hardwood garden room will depend on the size, design, glazing, roof specification and overall level of finish. As these projects are usually bespoke, pricing can vary significantly depending on the complexity of the design and the materials chosen.
-
In many cases, a garden room can be built under permitted development, although this depends on the size, height, position and other site-specific limits and conditions. Planning Portal says conservatories follow the same planning rules as other house extensions, so it is always important to check the position before work begins, especially for listed buildings or homes in protected areas.
-
Sometimes, yes. Garden rooms are normally exempt only when they meet conditions such as being single storey, built at ground level, under 30 square metres, separated from the house by external-quality doors, windows or walls, and having compliant glazing and electrics. Where those conditions are not met, building regulations approval is more likely to apply.
-
Yes, a well-designed hardwood garden room can be enjoyed throughout the year. With proper insulation, quality glazing and the right approach to heating and ventilation, the space can remain comfortable in both winter and summer, making it suitable for everyday use rather than just occasional seasonal use.
-
A hardwood garden room can work beautifully as a home office, studio, gym, hobby room or occasional guest space, provided it is designed around that use from the outset. Where the building is intended for sleeping accommodation or more intensive everyday use, the planning and building regulations position can become more important, so it is best to establish that early in the process.
-
A hardwood garden room will benefit from regular upkeep to keep it performing and looking its best over time. Maintenance guidance commonly recommends routine cleaning and periodic recoating of the timber finish, with one current UK guide noting a full re-coat is often needed at least every five years, depending on the timber, finish and weather exposure.
