Double garage with room above: hand-cut oak frame built to your site

A double garage with room above is one of the most practical investments a rural property owner can make. You get secure, weather-tight storage for two vehicles, plus a flexible upper floor—a gym, studio, guest annexe, or home office. But the right structure matters. It must suit your land, satisfy building control, add genuine value to your estate, and look as good as it performs. Off-the-shelf steel buildings cannot do this. Bespoke oak-frame construction can.

Green Oak Solar Frames is a craft-led maker based in the UK, specialising in hand-cut green oak structures that combine traditional carpentry with modern engineering. Every double garage we design is bespoke to your site, your planning context, and your budget. The frame is hand-cut solid green oak—the timber is felled and shaped by craftspeople, not factory-cut to a template. This means your structure responds to the actual contours and character of your property, and it weathers beautifully over time. Building control officers and planning committees know oak-frame construction; it reads as intentional architecture, not a warehouse dropped on a country estate.

The upper room can be anything you need. Some clients use it as a pool house or studio. Others create a guest lodge or holiday let that pays for itself. The layout, height, windows, and materials are all configurable via the live 3D tool—you design it, see what it looks like from every angle, and understand the cost before you commit. If you want integrated solar—roof tiles that generate electricity, battery storage, or EV charging infrastructure—those are built into the structure from the outset, not bolted on afterwards. The whole system can operate independently or feed back to the main house.

Planning permission is often the first hurdle. Councils scrutinise outbuildings carefully, especially in rural areas and conservation zones. A bespoke oak-frame design is far more likely to be approved than a standard portal frame because it demonstrates intent, landscape sensitivity, and architectural rigour. The hand-cut details, the proportions, and the material choice all signal that this is a considered addition to the property, not an industrial structure. Many affluent rural homeowners find that planning officers are more receptive to oak-frame proposals, particularly when the design respects local vernacular.

The cost of a double garage with room above depends entirely on your specification: the footprint, the height, the internal finishes, roof systems, and whether you integrate solar. That is why there is no fixed price on this page. Instead, use the live 3D configurator to build your exact design, and the tool will calculate the cost in real time. You can adjust the dimensions, add or remove features, and see the impact on price immediately. This means you are never quoted blind, and you never discover hidden costs mid-project.

The process itself is straightforward. You describe your site, your needs, and your budget. The studio creates your bespoke design in the 3D tool, which you review and refine remotely. Once you are satisfied, the frame is hand-cut and delivered to your property ready for assembly. The hand-cut oak is seasoned and shaped to order, so lead times reflect genuine craft rather than stock-holding. Building control and planning liaison are handled openly; the studio works with your local authority to ensure the design meets all technical and aesthetic standards.

What sets Green Oak Solar Frames apart is the integration of renewable energy into the structural design itself. Rather than treating solar as an afterthought, the roof system is engineered to house integrated photovoltaic tiles, battery banks, or charging points for electric vehicles. This means your double garage generates income, reduces grid dependency, and appeals to future buyers. For affluent rural property owners, this is not just storage—it is an investment in energy independence and estate value.

Many affluent rural homeowners have invested in double garages with traditional brick or timber-clad structures, only to find they lack flexibility, are costly to heat or cool, and add little to the property’s character. A bespoke oak-frame alternative is stronger architecturally, more adaptable to future needs, and far more distinctive. It also works harder: the upper room generates rental income, the integrated solar offsets energy costs, and the whole structure can be designed to complement the main house or existing outbuildings.

If you are ready to explore a bespoke oak-frame double garage with room above, start with the live 3D configurator. Build your design, see your cost, and understand what is possible on your site. When you are ready to move forward, book a conversation with the studio. There is no obligation, no sales process—just an honest discussion about what your property needs and what we can build for you.
