Size measured in metre

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

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.

Our 44mm Log Boards are a thick profile wall material, with a double tongue and groove fitting built-in, giving you a sturdier build.

The Devon Max is highly secure with tough, double-glazed glass windows and doors that feature a multi-point locking system with security measures like anti-pick, bump and drill door locking cylinders.

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.

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.

Garden buildings should not require planning permission, so long as they:

  • Are single storey
  • Do not exceed a maximum eaves height of 2.5m
  • Do not exceed a maximum ridge height of 4m (dual-pitched roof) or 3m (pent or other roofs)
  • Do not exceed a maximum height of 2.5m (if placed within 2m of a boundary)
  • Do not take up more than 50% of your outdoor space
  • Are not intended for permanent residential use

Garden buildings should not require building regulation approval, so long as they:

  • Have a floor area of between 15-30m²
  • Contain no sleeping accommodation
  • Are constructed at least 1m away from a boundary

Due to the large size of this building, we would advise checking your local planning permissions and building regulations before assembly. Depending on the distance to your land boundary, the size of your garden or the proposed location relative to any existing buildings, you may require planning permission.

The Devon Max has been designed to satisfy these rules where possible. This includes an interior space that is less than 30m², an eaves height that is less than 2.5m and an overall ridge height that is less than 4m. This means that it should not require planning permission or building regulations approval, provided there is no sleeping space installed. However, this cannot be guaranteed as planning permission and building regulation rules may vary depending on where you live. If you are unsure, always check with your local authorities before purchasing. For more information and any further queries, contact our customer service team.

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.

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!

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.

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.

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

Our simple finance options allow you to spread the cost of your purchase over 24, 36 or 48 months.Read more about our Pay by Finance option here.

Bright and Spacious Living

The Devon Max has been specially designed to have a wide, spacious feel and a bright interior. With an interior space that’s long and open even in the smallest model, you’ll never feel confined inside the cabin.

This space is improved even further with the huge beams of natural light that flow through it. With a set of either two or four broad windows (depending on your choice of model), sunlight easily floods the space, making it bright, airy and giving it a peaceful, open feeling.

Reverse Apex Roof

Not only does the Devon Max’s reverse apex roof look great and provide free-flowing drainage, it also gives the Devon Max a huge eaves height of 211cm or 6”9! This means that, even for the tallest of us, there’s no need to worry about space inside the Devon Max.

And, fitted with hard-wearing and waterproof green roofing felt, there’s no doubt that the reverse apex roof can take on the elements either. Combining an attractive finish, durability, and lots of room to move around in, the Devon Max’s reverse apex roof has been designed to look good and make your life easier.

Stylish Asymmetric Design

Your new Devon Max Cabin is not only tailored to have loads of space, but it’s also crafted to provide an iconic centrepiece for your garden too.

The design is a sleek, contemporary one, with wide windows and glass-centred doors that prioritise light flow into the building. The placement of these windows is particularly attractive and modern - laid out in an asymmetrical fashion that’s certain to catch the eye.

Easy-Access Doors

On top of the tall roof and bright interior, the Devon Max also has a set of tall and wide double doors. With these high-reaching doors, as tall as the doors inside your home, you won’t struggle for access in or out of the log cabin. They’re also inset with glass to let even more light inside.

The 6’1”, high-reaching, offset double door design is a unique feature that provides you with tons of headroom - allowing you to fully utilise the whole of the cabin space however you want to!

Premium Tongue & Groove Cladding

We provide strong and reliable premium log cladding with the Devon Max Cabin as standard!

Styrene Acrylonitrile (SAN) glazing is a high-strength rigid plastic glazing that’s UV-stable and shatter resistant. Aesthetically pleasing and safe to handle, it also comes at an affordable price.

Toughened, double-glazed glass is available as an upgrade. Features of toughened glass include added strength versus regular glass and double-glazing with a space between panes to reduce heat transfer.

For a log cabin that lasts the test of time, you can opt to have your building pressure treated. This is an effective way of keeping the building completely protected from the elements as well as other forms of damage.
