BESPOKE OAK FRAMES
Oak garden room kits you configure and build yourself
Green Oak Solar Frames makes hand-cut solid green oak garden room kits for self-builders and renovators across the UK. Use our live 3D configurator to design your exact specifications, add integrated solar roof tiles or battery storage if you choose, and we deliver nationwide. You own the build; we supply the precision-cut frame and support.
An oak garden room kit starts with one principle: you design it, you build it. Unlike off-the-shelf sheds or flat-pack structures, a bespoke oak frame responds to your site, your light, your budget and your timeline. We hand-cut every piece of solid green oak to your configuration—whether that’s a lean-to reading room, a studio workspace, a garden bar, or a standalone pavilion. The frame arrives on-site pre-cut and ready for assembly by you, a local builder, or a team you trust. This is not a kit where you guess dimensions or compromise on proportion. Every joint, every beam, every rafter is specified to your exact brief.
The live 3D configurator is where your project becomes real before any material leaves our workshop. You adjust the length, width and roof pitch; you choose between open-sided and fully enclosed walls; you specify window and door locations; you decide whether to integrate solar roof tiles, a battery system for off-grid storage, or EV charging infrastructure. The configurator shows you the frame in three dimensions, updates the material schedule, and calculates what your build will look like on your land. This removes guesswork. You see the proportions, the shadow line, the sightlines into and out of the space. Only when that image is right do you move to pricing and delivery.
Green oak is a living material. It has grain, colour variation, and character that no engineered timber replicates. As it seasons in situ, it will move, settle and darken—these are not defects, they are the signature of solid wood and time. For a garden room, this means your structure becomes more deeply part of the landscape with every season. The hand-cut joints—mortise and tenon, half-lap, simple lap—are traditional joinery that has held oak frames upright for centuries. We use modern precision tooling to cut them, but the language of the joint is old. That durability and beauty is what separates a timber outbuilding from a temporary structure.
Adding solar to an oak frame is straightforward if you plan for it. Integrated solar roof tiles sit flush in the roof plane; they generate electricity on cloudy days as well as sunny ones, and they tie into an inverter and battery system if you want to store energy or run off-grid. If your garden room will be a studio, a home office, or a guest space, solar can power lighting, heating, and low-draw appliances without a grid connection. You decide at the configurator stage whether solar is part of your brief. If it is, we factor it into the roof structure and the electrical layout. If not, the frame works just as well as a passive timber shelter.
Self-builders and renovators come to us because they are specific about quality and timeline. You are not buying a one-size-fits-all product; you are specifying a structure that fits your land and your vision. The configurator speeds up the conversation between your idea and our precision cutting. We deliver nationwide, which means your site location does not limit your options. Once the frame arrives, assembly is a known quantity—you have the cut list, the joint schedule, and the support to understand what goes where. Many clients bring in a local carpenter or builder for the final stages; others assemble with friends and family. The frame itself is the hard part; we do that. The rest is scaffolding, fastening and finishing—work you can own or delegate.
Pricing for an oak garden room kit reflects the size, the roof complexity, the wall specification and whether you add solar or storage. There is no single starting figure because a 4m × 3m open pavilion costs differently from a 6m × 5m enclosed garden room with solar tiles and a battery. The live 3D configurator updates the material cost and delivery estimate as you adjust each parameter. Use it to explore what your budget can build, or use it to price the exact vision you already have in mind. When you are ready to move forward, you will have a full quote, a delivery date, and a cut list ready for manufacture.
The community of self-builders and property renovators choosing bespoke oak frames is growing precisely because off-the-shelf answers do not fit renovation sites or bespoke builds. Planning departments and conservation officers often favour timber outbuildings that sit well in the landscape. An oak frame, especially one that responds to local vernacular and site conditions, tends to get approval where anonymous garden buildings might not. We cannot speak for planning officers, but we know that the self-builders we work with report fewer objections and smoother conversations when the outbuilding is part of a considered, craft-led design rather than a standard product.
Every oak garden room kit we make is a proof of concept for the next one. We learn from each configuration, each site challenge, each finish choice. This is how a young, craft-led maker builds a reputation—not through decades of sameness, but through commitment to precision, to listening to what you need, and to delivering a frame that will outlast the original builder. Your garden room is not a commercial project for us; it is a craft. That distinction matters when you are investing in a structure you will live alongside for decades.
Start with the live 3D configurator. Spend twenty minutes understanding what your budget, your site and your ambition can build. Upload your site dimensions, adjust the frame to fit your sightlines, add solar if it interests you, and see the quote update in real time. You are not committing to anything; you are exploring what bespoke actually means. Once you have a configuration that resonates, reach out. We will talk through the build timeline, delivery logistics, assembly support, and any site-specific details. This is a conversation between makers and builders, not a transaction between vendor and customer.

Frequently asked
What is the difference between an oak garden room kit and a prefab shed?
An oak garden room kit is hand-cut to your exact specifications using solid green oak and traditional joinery. A prefab shed is mass-produced to standard dimensions with engineered materials. Our kit responds to your site, your light, your roof pitch and your finish choices. It is a bespoke structure you assemble; not a product you install.
Can I add solar panels to an oak garden room kit?
Yes. Integrated solar roof tiles can be designed into the frame at the configuration stage. They sit flush in the roof plane and tie into an inverter and battery system if you want off-grid storage. You specify this in the 3D configurator and we factor it into the roof structure and electrical layout.
How do I know what my oak garden room will cost?
Use the live 3D configurator to adjust length, width, roof pitch, walls, windows and solar options. The configurator updates the material cost and delivery quote as you design. Once you have a configuration you want to build, we provide a full quote and a delivery date. There is no single starting price because every kit is bespoke.
Do you deliver outside the South East?
Yes, we deliver nationwide across the UK. Delivery costs and timelines are calculated in the live 3D configurator based on your postcode and the size of your frame.
Do I need planning permission for an oak garden room kit?
Planning permission depends on size, use, location and local authority policy. We recommend you check with your local planning department or a planning consultant before specifying your frame. Many self-builders find that a bespoke timber outbuilding faces fewer objections than a standard garden building, but this varies by site.
