2. Select Treatment

Untreated

Log boards are delivered to you untreated, providing you with a natural wood appearance. You will need to treat this annually and after assembly to protect your wood against rot or decay.

Pressure Treated

For increased longevity you can opt for pressure treatment. In a pressurised tank chemical preservatives are forced deep into the wood’s fibres to resist rot or decay. Upgrading to Pressure Treated means you also get an extended 15 year guarantee.

2. Customise

28mm

Solid profile single Tongue and Groove for strength and durability. Great for medium to large buildings ideal for seasonal use.

44mm

Our 44mm Log Boards are a thick profile wall material, with double tongue and groove built in, giving you a sturdier build, protecting against drafts and water ingress for better weather resistance and insulation. Great for large buildings intended for all year round use.

11mm Tongue and Groove

Our Standard flooring option which provides a durable, solid foundation and underfoot to the building. The 11mm option is ideal for less demanding and frequent usage, suitable for lighter intensity purposes like summer houses and other living spaces containing light furniture. The 11mm tongue and groove timber makes this a solid yet suitable, economical option.

19mm Tongue and Groove

1.7 times thicker than our standard 11mm flooring, our premium floor is the perfect choice for higher intensity usage. The construction uses thick 19mm Tongue and Groove timber, which gives you not only the strength, but better insulation against the cold weather. This specific floor is the perfect option if you’re planning on using the building as an everyday use office, gym or games room with heavy objects.

Single Glazing

Crafted from shatter-resistant plastic (SAN) and suitable for seasonal use. SAN is used for its UV properties and the tougher finish avoids breakages, when compared to glass. Single glazing is the perfect choice for seasonal buildings such as summerhouses and sheds providing plenty of natural light into the building.

Double Glazing

Created from toughened glass, the double glazing is the ideal option for a building which is used all year round. The extra thickness will provide better insulation and keep your building warmer in those colder months of the year.

11mm Tongue and Groove

Our standard roof option, this interlocking roof provides a reliable covering for any building. The Tongue and Groove not only gives your building a stronger roof but also a premium look and feel.

19mm Tongue and Groove

Heavy-duty and long-lasting, our 19mm roof will provide you with extra insulation for those colder months of the year and ideal for larger buildings.

3. Add Extras

Complete your building with optional shelving, guttering, base options, assembly kits and more.

Untreated: Log boards are delivered to you untreated, providing you with a natural wood appearance. You will need to treat this annually and after assembly to protect your wood against rot or decay.

Pressure Treated: For an extra level of protection, you can opt for pressure treatment which is an effective way of keeping the wood long-lasting. This is an extra step in the manufacturing process where the wood is treated in a pressurised tank. Chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. When you upgrade to Pressure Treatment, the guarantee is extended from 10 to 15 years.

28mm is our standard log cabin cladding, which gives the building reasonable durability and insulation whilst remaining affordable. 28mm is a single profile and ideal for seasonal use.

Our 44mm Log Boards are a thick profile wall material, with a double tongue and groove built-in, giving you a sturdier build. Our 44m cladding is 57% thicker than our standard 28mm cladding option and has a solid and rigid construction, so you can look forward to enjoying your log cabin all year round, no matter the weather.

Roof:

We offer two roof thickness options, so depending on how you’re going to use your log cabin, you can choose the better option for you.

The first option is our standard 11mm thick board that interlock together, providing you with a solid roof for basic use. If you’d prefer something more robust for more heavy-duty use, such as a home gym, the upgrade option is a 19mm roofing that provides extra strength and durability to your log cabin.

Floor

We offer two flooring thickness options, so depending on how you’re going to use your log cabin, you can choose the better option for you.

The first option is our standard 11mm thick board that interlock together, providing you with a solid base for basic use. If you’d prefer something more robust for more heavy-duty use, such as a home gym, the upgrade option is a 19mm flooring that provides extra strength and durability to your log cabin. This upgrade option is perfect for housing heavy equipment and withstands the knocks and spills of everyday life. We supply timber bearers with both flooring options.

All garden buildings should be assembled on a firm and level base. A base will ensure your building has a solid, long-lasting and well-drained foundation.

If you want to build your own base, from a sturdy material such as concrete or flagstones, you can find minimum dimensions for each size of this building in the tech specs. In order to protect your building from moisture, you should leave a 2ft gap around the exterior of your building, so remember to take this into consideration when laying any sort of base.

Our robust and simple to use EcoBase provides you with a firm, long-lasting foundation with suitable drainage for your garden building. It is quick and easy to install through the use of snap connectors that link the grids to each other.

Single Glazing is used as standard. Our single glazing is crafted from shatter-resistant plastic (SAN) and suitable for seasonal use. SAN is used for its UV properties and the tougher finish avoids breakages when compared to glass. Single glazing is the perfect choice for seasonal buildings such as summerhouses, log cabins and sheds providing plenty of natural light into the building.

You can upgrade to Double Glazing. Crafted from toughened glass, double glazing is the ideal option for a building that is used all year round. The extra thickness will provide better insulation and keep your building warmer in those colder months of the year.

If your building is shorter than 2.5m you should not require planning permission, (unless it’s more than 50% of your garden or will be placed in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before purchasing a garden building from us.

We do not offer an installation service on any of our buildings, as they are designed to be easy and simple to assemble. Using the digital assembly instructions included in your order confirmation and a team of at least 2 people, the interlocking logs that simply slot together mean you will have your BillyOh building up in no time!

Our Log Cabins arrive as individual boards that are designed to be easily slotted together. This makes assembly easy and gives a strong building with interlocking corners for strength. If you opt for double glazed windows and doors, these are delivered pre-assembled for your convenience.

The Devon is versatile and you can transform it into whatever you like! The cabin is ideal for use as a home gym or games room where you can entertain your friends, or you could choose to turn it into a living space where you and your loved ones can relax in the comfort of your garden. The Devon is also ideal to turn into a home office, perfect for those who work from home or run a business from home.

The offset design of the doors offers maximum floor space away from the doors, allowing room for larger furniture items such as desks, gym equipment and soafs - whatever you like!

We offer two roof and roof thickness options, so depending on how you’re going to use your log cabin, you can choose the better option for you.

We offer a pay by finance option on any purchase over the value of £560.

Long-Lasting Protection With Tongue & Groove Cladding

The cabin is a solid, interlocking structure made from Tongue and Groove cladding, giving stability and security to the building and its contents. Tongue & Groove construction also offers a tight seal against water ingress. And with the option of 19mm thick flooring and roofing, you can get even more protection. Depending on how you’d like to use your cabin, our various cladding options will meet all your requirements.


We offer 2 Tongue and Groove cladding thicknesses: 28mm and 44mm for extra insulation. Thick, interlocking 28mm or 44mm cladding walls lock out even harsh weather conditions making sure you’ll always be warm and dry in your outdoor building. Likewise, when the weather’s warmer, the beautiful, long windows and doors will keep you cool as you enjoy the summer sun. If you wish to be even more protected then we offer a selection of roof thicknesses. 11mm and 19mm roof thicknesses will keep any moisture out of your cabin keeping you dry and your belongings undamaged.


We offer two flooring thickness options, so depending on how you’re going to use your log cabin, you can choose the better option for you. The first option is 11mm thick boards that interlock together, providing you with a solid base for basic use. If you’d prefer something more robust for more heavy-duty use, such as a home gym, the upgrade option is a 19mm flooring that provides extra strength and durability to your log cabin. This upgrade option is perfect for housing heavy equipment and withstanding the knocks and spills of everyday life. We supply timber bearers with both flooring options.


Pressure Treatment Options

For a completely protected garden room, you can also opt for a pressure treated building which is an effective way of keeping the building completely protected from the elements as well as rot and insect infestation.


The pressure treatment penetrates the wood with preservatives, leaving you with a building that is low maintenance and doesn’t need treating at home. This option is great for anyone who is looking for a building that's not going to take any effort to look after - especially as we increase our BillyOh guarantee to 15 years on all pressure treated buildings!


Choose your Doors and Window Option

If you wish to use your building as a summer getaway, the single glazed windows and doors will be perfectly suitable for you. The double glazing option we offer enhances the safety, and reliability of the cabin and also shuts the cold weather out; ideal if you’re looking for a cabin for year-round use.


Add the Finishing Touches

You can further customise and enhance the building by putting your own personal stamp on your new Devon Log Cabin by painting and decorating it. We recommend adding an annual treatment or paint for untreated cabins for the best weather and heat protection to keep them in their best condition and looking pristine for years to come.


Our premium paints come in a wide variety of colour choices that will bring your cabin to life, or for a more traditional look, we also offer a range of natural-look wood treatments. Or to enhance the natural beauty of this style of cabin, use an oil or water-based wood stain to protect the wood against rot.


Easier and Better For You

At 2.36m tall at the ridge, you'll have all the headroom you need to house tall furniture and equipment or hang lights in your cabin. The eaves height, which is the lowest point of the roof at 2.04m, has also been raised to allow for a higher ceiling, keeping your cabin feeling fresh and airy. The tall 6’1” double doors give extra entrance clearance; perfect for adding and transporting furniture. This also prevents the need to duck down as you enter the cabin.


Planning Permission

The BillyOh Devon has been designed at 2.36m tall to comply with most planning regulations. Depending on location and intended use, planning rules vary, therefore we advise you to contact your local borough council for more information regarding planning permission and building use restrictions before purchase.
