Oak framed garden rooms bring warmth and versatility to any home. You can opt to have your garden room as a standalone structure, creating a refuge away from the house, or attached to the back of your home to create additional living space.
Choose between two types in our Online Designer: the garden room and orangery. The garden room design is a simple yet effective room that you can use either as an extension or freestanding structure.
If you’re looking to expand your home with architectural impact, an orangery is a more elaborate variation, making a grand architectural statement. Our orangeries feature a central oak-framed section with a gabled roof, flanked by two flat-roofed wings. The layout allows for generous width and an abundance of natural light.
When connected to the main house, a garden room becomes a place for relaxation and togetherness, ideal for open-plan kitchens, dining spaces or peaceful reading corners.
When built as a separate structure away from the house, the increased privacy creates a space for all kinds of uses, from sunrooms and studios to pubs and guest houses.
Whatever the purpose, garden rooms and orangeries become an integral part of your family home with a strong connection to the outdoors.
Glazing fitted between oak beams creates a sense of space, filling the room with natural light as you enjoy panoramic views of your garden. We prepare your frame with the glazing method of your choice ready for easy installation of your own glazing. Furthermore, the solid roof helps maintain an ambient temperature, so you can enjoy the space year-round.
A solid oak framed garden room offers a striking visual for you and your guests to admire, from inside and out. Suitable for both sleek modern homes and period properties, the warmth and elegance of oak framed garden rooms are timeless.
Our artisans craft your timber frame using the best construction-grade oak. We use traditional mortise and tenon joinery to connect the frame, utilizing the natural movement of the oak to reinforce the structure once assembled.
Our hands-on approach makes sure the carpentry receives careful attention. By planing each section before a light sanding, beams and rafters are smooth to the touch with a prestigious finish.
Built to last for centuries, both garden rooms and orangeries bring warm homely charm and the timeless character of exposed oak to your home.
Wondering what a kit form garden room looks like? The below picture shows how it'll arrive at your location.
We've put together a booklet of detailed answers to our most commonly asked questions. A perfect in-depth read about buying your oak structure from us.

Designing your bespoke garden room has never been easier. Our intuitive Online Designer puts you in control. Adjust the size and features and watch the 3D model and live pricing update in real time. With complete confidence in the price, you can enjoy seeing your vision take shape. Here’s how each control shapes the garden room.
To begin, choose between an ‘Orangery’ or ‘Garden Room’. Pick ‘Garden Room’ if you want a standalone structure or a simple rectangular extension.
Choose ‘Orangery’ for a more elaborate design ideal for larger footprints and building along an existing wall.
Width (m)
If you’ve picked the ‘Garden Room’ option, select a width between 3m and 4m. For the ‘Orangery’ design, this control adjusts the central section, with the same 3m to 4m range.
Length (m)
You can extend the garden room by increasing the length. Pick a size between 3m and 9m.
Depth (m)
The depth will only appear with ‘Orangery’ selected. This measures how far the orangery extends from the building. Choose any measurement between 3m and 4m.
Side Widths (m)
The side width only applies to the orangery design. This controls the size of the two side frames. Adjusting this control will change both sides equally. If the available sizes don’t suit your needs, contact us and we’ll talk you through your options.
Clearance Height
You can change the clearance height using this control. Choose between 2.1m and 2.5m. The clearance height is the measurement from floor to eaves, including the brickwork the frame sits on. With orangeries, this control adjusts both centre and side frames.
Roof Height
The greater the roof height, the steeper the gradient. Keep in mind, changing the roof dimensions affects the overall height of the garden room. Choose between 0.9m and 1.8m. For the Orangery design, this will only adjust the gable height in the centre frame.
Main Section Sizes
The 'Thickness' determines the cross-section size of oak beams and main rafters. Choices are 150mm, 175mm, or 200mm. Your choice depends on preference and does not affect structural integrity. Slimmer beams suit contemporary spaces with a sleek aesthetic, while thicker beams create a more traditional rustic character.
Roof Boarding
With battens and shingles installed, the underside is visible when inside the garden room. Boarding conceals the underside of battens and shingles, creating a uniform aesthetic. If you’d like to add boarding, you can pick between British larch, British cedar and European oak. For no boarding, select ‘None’.
Roofing Battens
Battens run at a right angle to rafters to create a fixing point for tiles. You can source your own by selecting 'No Roofing Battens'. Otherwise, choose between ‘Pressure Treated Softwood’ or ‘European Oak’ battens.
As a general rule, if you're using boarding, battens are concealed, so softwood is a practical choice. But if you’re leaving them exposed, oak battens offer a refined, premium finish.
Roofing
To enhance the natural look of the garden room, you can include cedar tiles. Untreated cedar shingles will last at least 20 years. You can extend the lifespan with treatment.
We also offer BritMet Tiles. These durable composite tiles have a long lifespan and come in different finishes, including oak, charcoal, slate and sunshine. Press the ‘?’ to take a closer look at the colour.
If you have existing tiles on your property, you may want to use the same tiles for continuity. If so, you can source your own tiles by selecting 'None'. Each structure is robust and can easily withstand the weight of a full set of ceramic or slate tiles.
Dwarf Wall Size
A dwarf wall is the brickwork on which the garden room stands. We don't supply brickwork, but we prepare the frame depending on your choice.
You can have different heights; 225mm, 450mm and 675mm. Consider whether you’re fitting electrical sockets and radiators. These factors often determine the best height. If you want a custom height, simply select custom and input the size.
Door Positions
The 'Door Position' decides where the door will go. Choose between front, left or right. We'll design the frame so that the door is central.
Glazed Oak French Doors
You can also add solid oak glazed French doors to the garden room. The French doors typically fit on the front of the orangery, creating a grand walkway into your outdoor space. Please note, ironmongery isn’t supplied.
While we don't supply glazing, we need to prepare the frame for the glass. The Glazing control allows you to choose which glazing method you’d prefer to use. These are:
All glazing choices are direct glazing, meaning the glass sits straight into the frame. 'Rebate and Bead' is the most subtle finish, leaving the main oak frame visible from the outside of the garden room. The other two methods result in visible coverboards from the outside.
Glazing requires professional installation. Moisture movement causes the oak frame to shrink, so adequate sealing is necessary. Consult a professional, or if you’re unsure, call us and we can help.
In the gallery section, you can look at oak garden rooms once installed. There's a diverse range of ideas you can use for inspiration. Remember, all Oak Timber Structures garden rooms are bespoke, so whatever the shape or size, we can make it unique to you.
Bespoke means the garden room is specific to you and your needs. Because we make each garden room from scratch, we can customise the size, design and roof shape. You're not limited to square garden rooms, whatever shape you need, we'll make it happen.
So whether you want a garden room to fit a specific space, or want something out of the ordinary, contact us and we'll turn your ideas into a reality.
CAD is an abbreviation of 'Computer Aided Design'. Once you place an order, we begin by making sure every measurement is exact. Once you've approved the CAD, we'll use this to build your garden room. Likewise, builders use CAD drawings to prepare footings and build the dwarf size wall.
Yes. We carry out a trial assembly at our workshop to make sure everything fits to perfection. This also gives us the opportunity to code each piece. Your builder can work alongside the Parts Identification Drawing to match the parts and joints. Each part is prepared, coded and double-checked before delivery.
As oak specialists, we supply the oak frame and rafters for your garden room. Should you choose, you can add boarding, battens, roofing and doors.
We prepare the oak with your chosen method and include the timber glazing bead to hold the panes in place but you'll need to source custom glazing to fit into your garden room. Many companies are offering their services, and we recommend comparing quotes. We're happy to liaise with your chosen supplier to ensure correct sizes.
Please note, we don't supply brickwork. So make sure your dwarf size wall and footings are in place before the kit form oak garden room arrives.
Your garden room kit comes with a full timber roof with exquisitely exposed oak trusses and supporting rafters.
You can choose to include cedar shingles or BritMet tiles in your kit. Untreated shingles last upto 20 plus and add to the natural warm aesthetic. Treated shingles have a darker colour and usually add an extra 5 years or more of onto the shingles lifespan.
Battens are included if selected and provide a fixing point for the shingles or tiles. If you prefer, you can source your own tiles or shingles. Our oak frames can support the weight of slate tiles or any material of your choosing. You can source these tiles from a standard builder's merchant.
Another common question is on guttering and insulation. It’s best to seek your builder's advice on this. Because each garden room is different, the needs vary depending on the specs of each garden room. A builder may also suggest further roofing materials to seal and make it watertight.
Every building needs a solid foundation. A garden room is no different. Once you've approved the CAD drawing, the builder can inspect the desired location. Depending on the condition of the ground, requirements may vary. We can provide a PDF guide outlining standard foundations so your builder can use it as a starting point.
Garden rooms sit on a shallow course of bricks that are not provided in the kit. How high you want the brickwork is up to you.
Depending on the height of the brickwork, we cut the beams to match the overall size. Your builder can then work with the drawings, knowing that the oak frame will stand on top.
Crafted by our skilled artisans, the woodwork for your garden room is complete. Building requires connecting the pieces and hammering the oak pegs into place.
It's important to do this within four weeks of manufacture. As moisture leaves the oak, slight shrinkage occurs, and the oak tightens around the joints, making the structure naturally more robust. Prolonging storage for too long can cause joints to become misaligned.
You'll need to screw in the rafters and that's it. Some builders recommend hiring a genie lift for heavy lifting. These lifts carry the weight of oak beams, so joining is much more straightforward.
Oak is a durable timber, so maintenance requirements are minimal. That said, there are tips and tricks you can use covered in the article 'Maintaining Your Oak Structure.'
Sometimes during handling and building, the frame can pick up marks. So, you can power sand upon completion to remove such marks to achieve the perfect final finish.
We use mortise and tenon joinery techniques for the main frame of an oak garden room. This technique holds the frame together using the provided oak dowels. To further increase stability, fix other pieces together using screws.
The common rafters are the roof beams fixed at intervals between the principal beams of the mainframe. For common rafters, use 150mm stainless steel screws. It's integral you use stainless steel screws because non ferrous metals such as iron react with the tannins from the oak.
Links to 150mm stainless steel screws:
The battens form a fixing point for tiles and shingles. To attach these screw them onto the rafters. These need fixing with 40mm stainless steel screws.
The technique depends on whether you're screwing into softwood or oak battens. Fixing into softwood battens is easy, but as oak is much harder, so you'll need to pre-drill pilot holes for the screws before assembly.
Again, if you selected oak for your battens, ensure stainless steel fixings are used.
If you've selected boarding, you should also use 40mm stainless steel screws. The boarding fixes to the garden room rafters below the battens. With boarding in place, you can then fix battens across the boarding.
Oak battens aren’t needed if you use boarding as they will be concealed between the boarding and shingles so softwood battens are a cost effective alternative.
Boarding is susceptible to moisture movement, meaning it can expand and contract. To reduce the effects of moisture movement, please read the sealing information.
To fix boarding, we recommend pre-drilling and holding in place with the head of the screw so it can move if required. Don't butt it tight together and leave a small gap between the tongue and the groove joints to allow for moisture movement.
As discussed, boarding is prone to slight size change because of moisture movement. So, you must seal it before the installation. Use a waterproof oil such as OSMO UV Protection Oil on all four sides to reduce warping.
The type of nails you use for fixing the cedar shingles depends on the battens. If you're fixing on to softwood battens, use Silicone Bronze ARS Nails. The natural acidity of the cedar won't corrode bronze.
Links to Silicone Bronze ARS Nails 31mm x 1.8mm:
As solid oak is a tougher wood, you'll need thicker nails. So, if you're attaching cedar shingles to oak battens, use larger nails. Remembering to use stainless steel for the oak.
