Expertly Crafted Solid Oak Garden Rooms

Also known as: Orangeries, sun rooms, conservatories

Oak Timber Structures supply the highest quality and most luxurious oak framed garden rooms. Every oak frame we produce is different to suit your requirements.

All sections are planed all round and lightly sanded to ensure the perfect finish and supplied in a kit form to keep the costs to a minimum for the client or builder to erect with ease.

CAD drawings are initially supplied for your changes and approval before we start to manufacture the oak frame. We then select the finest oak freshly cut oak and begin to manufacture the individual oak frame. All holes are pre-drilled and traditional mortise and tenon jointing is used to ensure the highest quality of craftsmanship is used throughout the build of your oak frame. Oak pegs and curved oak braces are also supplied. The frame is then erected in the timber yard, coded and de-assembled for delivery.

Our oak framed garden rooms slot together perfectly and are secured by knocking in our oak pegs, which will tighten the frame up instantly and continue to tighten as the oak frame mellows to its surrounding.

All of our oak frames are individually, expertly crafted with joinery techniques that have been used for hundreds of years and will look more beautiful with age, whilst still keeping the elegant and luxurious homely feel.

The timeless feel of your oak framed garden room will never reduce and will allow you to appreciate the beautiful outdoor views of your garden whilst relaxing in a strong, natural oak framed building.

Feel free to call us or you could even email us a sketch of your desired oak garden room. The simplest of sketches can be designed into the most beautiful looking oak frames.

How Your Garden Room Will Arrive

Your garden room will arrive in kit form packaged like the following:

Using the Oak Garden Room Controls

You can design your own bespoke garden room by using the controls above. The 3D Model will then change depending on the options you select.

Garden Room Size


The size control lets you select one of the pre-set sizes (3x3m or 4x4m) or select custom to type in your own width and length dimensions.


The custom control is only shown when the Custom option is selected in the size control. This allows you to type in your own width and length dimensions within our limits.


The Thickness control allows you to choose the section size of each of your posts (175mm posts are usually the most popular).

Roof Height

The roof height allows you to choose how high you would like the roof to be within our limits

Boarding | Battens | Roofing


The boarding control allows you to select whether you want:

  • No Boarding
  • Cedar Boarding
  • Larch Boarding
  • Oak Boarding

Boarding is optional and depends on the on the use and installation requirements of your garden room.


The Battens control lets you select whether you would like:

  • No Battens
  • Softwood Battens
  • Oak Battens

Battens will be required to fix your shingles or tiles to, and they sit across the rafters.


The Roofing control lets you decide whether you have:

  • No Shingles
  • Untreated Cedar Shingles
  • Treated Cedar Shingles

If you need to match the tiles of an existing building then feel free to source your own tiles.

Dwarf Wall Size

Dwarf Wall Size

The Dwarf Wall Size Control lets you set how high you are going to build your wall (Brickwork is not included). You get the options of 225mm, 450mm and 675mm. If you’re fitting electrical sockets and radiators check, which height you should go for, with your building control officer


Door Openings

The Door openings control lets you decide which sides of the garden room you want to put a door in. You can place a space for a door on any side you like. Each doorway will be positioned in the middle of the chosen side.


The doors control allows you to choose whether or not you want pre-glazed doors or not. If you select to have the doors they will be automatically assigned to each opening you have selected in the door opening control.

Glazing Methods (Glazing Not Supplied)


The Glazing control allows you to choose which glazing method you would like to use:

We provide three options to support glazing units (provided by others). These options are referred to as "direct glazing", meaning the glass sits straight into the frame. The first option, "rebate with cover board" is the most popular method. The first two options with cover boards result in you seeing the coverboard on the outside of your garden room. If you look closely at the garden room in the photograph at the top of this page, you'll notice that it's these outside boards you're looking at, rather than the actual oak of the frame itself.

We do offer the "rebate and oak bead" method, which some people prefer so you can see the oak frame itself. Please note this will require sealing very well to take into account any movement of the oak frame as it dries.

Frequently Asked Questions

Made to measure

Because each Garden Room is crafted from scratch, we can make any size you'd like, with any design or roof shape. You're not just limited to square Garden Rooms, they can be made to fit any area, even if every side needs to be a different length.

Each room is designed on computer first to make sure every single measurement is exactly what you need, then our craftsmen use their knowledge and skill to translate the design into the exact angles and cuts to bring it to life.

Each frame is constructed in our yard so you can be confident everything fits together correctly. While in our yard, all of the joining pieces are labelled, so when your builder comes to erect the Garden Room at your home, it's simply a case of matching the marked pieces back together.

Supply of Oak Frame

As oak specialists, we provide the oak frame and rafters for your Garden Room. You have the choice of solid oak or softwood rafters, depending on whether they will be seen or not. There are many companies across the UK that will offer you advice on the many different types, features and standards of glazing that can be custom made to fit into our Garden Room frames.

We provide the glazing strips to hold the panes in place as well as all of the measurements that your glazer will require.

Roofing your Garden Room

Your kit comes with a full, structured timber roof with beautiful Oak Trusses and supporting rafters.

You can optionally purchase cedar shingles from us too. Untreated shingles are the most common and will still last 20+ years. Treated shingles have a 25+ year lifespan but are a very dark brown colour. Untreated is the most popular choice.

The oak frames are strong enough to take slate tiles if you'd prefer. These can be sourced from a standard builder's merchant.

You will need further roofing materials to fully seal and optionally gutter and insulate your garden room roof. This advice can vary from builder to builder based on their previous experiences. We can talk to your builder about different options if required.

Groundwork and Supporting Brickwork

As with any building, the ground will need to be properly prepared to provide a solid foundation for your Garden Room. You should ask your builder to take a look at your location as each case may have different requirements. We can provide a PDF guide for a standard type of foundation that your builder can use as a starting point.

The standard Garden Rooms in the 3D builder above are designed to sit on a shallow course of bricks that are not provided in the kit.

Because our frames are expertly made each time, if you'd prefer to have the bricks higher we can accommodate this without problem.

Regardless of the height of bricks you choose, all of the measurements will be specified for both the bricks and the oak frame in the technical drawings we produce when you order. Your builder can then work to the drawings knowing that the oak frame will site perfectly on top.

Constructing your Garden Room

All of the woodwork for your garden room is already complete, so building it is an exercise in connecting all the pieces together and hammering the oak pegs in for the main frame and using stainless steel screws to hold the rafters in place.

Each part of your garden room is labelled to match its corresponding part, so once you identify which pieces fit together, it's a case of holding them in place while you fix them.

Builders will often hire a "Genie lift" to do the heavy lifting.

After Constructing Your Garden Room

We always recommend giving the beams of your garden room a power sand once the frame is constructed to remove any marks caused by storage, handling and building, in order to achieve the perfect final finish.

Our Oak Garden Rooms are delivered ready for assembly at your site by you or your builder. Allow an approximate 9 - 11 weeks (from drawing sign off) lead time for us to make and deliver your bespoke Oak Garden Room.

How To Order Your Oak Framed Garden room

All major cards
securely accepted

Ordering from Oak Timber Structures is straightforward. Nevertheless, our team is on hand to help throughout the process. Here are the simple steps to order a bespoke oak garden room:

  1. First, create the oak garden room using the designer or send drawings to
  2. For online orders, click ‘Add to Basket’.
  3. Navigate to your shopping basket where you can checkout securely online. We accept all major credit cards excluding American Express (as image). If you run into any checkout issues, please contact us using the online chat or call us and we’ll talk you through the process. Alternatively, you can order over the phone.
  4. We then produce technical drawings for you to sign off and gain approval from a structural engineer if needed. CAD drawings take between 2-3 working days to produce.
  5. If you are unhappy with an aspect of the drawings, we encourage you to call and seek advice from our helpful and friendly staff. They’ll revise the drawings accordingly and send them back to you for re-approval.
  6. Once signed off, we add your structure to the production queue and create it according to the stated lead times. During this time, many people use the approved drawings to get their groundwork in place if required.
  7. Our skilled team assembles the oak garden room to make sure there are no issues. This also allows us to code all components for seamless assembly. We then dismantle the garden room and organise it into transportable kit form.
  8. If you're running behind schedule, we're happy to store your structure for up to 4 weeks at no extra charge. Please note that we limit storage to 4 weeks. As green oak dries, it shrinks. Shrinkage is normal. In fact, our skilled staff prepares your structure for shrinkage to fuse joints, making them tighter and more robust. Yet, after 4 weeks, joints can become misaligned and harder to assemble, so it's important to limit storage time.
  9. We schedule delivery by liaising with you once your bespoke oak garden room is complete.
