Many garden rooms fall under permitted development, but it depends on things like size, height, placement, and how the room will be used. In parts of London, there can also be extra considerations (for example, listed buildings or conservation areas). We’ll talk it through with you based on your property and the proposed design.

Costs vary based on size, specification, insulation, glazing, and internal finishes. As a rough guide, a simple, well-insulated garden office-style room is usually more affordable than a larger annexe or a specialist space like a studio or wellness room. We’ll give you a clear quotation once we know what you want, with options where they’re helpful.

Timelines depend on the design stage, materials, and the complexity of the build. Smaller projects can be quicker, while larger bespoke builds naturally take longer. Once we’ve scoped your project, we’ll give you a realistic schedule and keep you updated throughout.

Yes — if it’s built properly. Year-round use comes down to insulation, heating, ventilation, and build quality. We design insulated garden rooms specifically to feel comfortable in winter and usable in summer, not just for the warmer months.

Almost anything: garden offices, gyms, studios, salons, games rooms, guest space, hobby rooms, or simply a quiet place to read and get some headspace. The best builds start with how you want to use the room day-to-day, then we design around that.
