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.

Untreated: Our log boards are delivered to you as untreated. Not only does this provide you with a lodge appearance, but allows you to decide the treatment type and colour which suits your tastes. You will need to treat this annually and after assembly to protect your wood against rot, decay and insect infestation.

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.

With the Devon an 11mm tongue and groove floor and roof is included but you can upgrade to 19mm to suit more intensive use.

Roof:

11mm: 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: Heavy-duty and long-lasting, this roof will provide you with extra insulation for those colder months of the year.

Floor:

11mm: 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: A 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.

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:

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.

Double Glazing:

Built 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.

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.

Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order via your online account, email or text to provide updates on delivery dates.

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