1. 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.

1. 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.

The Cove Multiroom has 2 distinct rooms and a beautiful canopy area.

The main room when you enter the building is a spacious 3.0m deep and 3.3m wide, giving you plenty of room for a summerhouse, outdoor home office or entertainment space.

Stepping through the boarded door and interior wall, you will find a 4.5m deep by 2.1m wide side room, with plenty of room for an office space, storage or any other use you can think of!

Lastly you have the beautiful outdoor canopy space which is 1.6m deep and 3.5m wide - plenty of room for entertaining with drinks or dining al-fresco in the warmer months.

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 or decay.

Pressure Treated: For a more protected building, you can opt for a pressure treated building which is an effective way of keeping the building long lasting. This is an extra step in the construction 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.

44mm is a thick profile with double Tongues and Grooves for additional strength, durability and weather protection. Great for large buildings intended for all year round use, it provides structural integrity and natural insulation for your log cabin.

We offer a range of roofing and flooring options, so depending on how you’re going to use your log cabin, you can choose the better option for you.

Roof:

11mm T&G: 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 more 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 and provides a 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, economic 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.

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 the properties of glass shattering. 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.

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.

If the building is shorter than 2.5m tall you should not require planning permission, (unless it’s more than 50% of your garden or to be put in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before ordering from us.
We do not offer an installation service on any of our buildings, our buildings are designed & made to be easy and simple to assemble. Using the assembly instruction included and with a team of just 2 people and a bit of DIY knowledge you can expect to have your BillyOh building up within a day, or as little as 3-4 hours with some of our smaller buildings.
Our summerhouses and sheds are delivered in easy to assemble panels. For your convenience the panels are no wider than 4ft so they can be easily maneuverable and fit through a standard doorway. Our Log Cabins arrive as individual boards that are designed to slot together.
Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order by our helpful care team to arrange delivery of your building.

We understand the need to secure your building, especially with larger Cabins. That’s why with every purchase of the Cove Multiroom we have included a secure door handle with a 5 lever locking system for the best security.

Alongside this you have our thickest, heavy duty 44mm wall logs and each window has a Lockable Casement Fastener to ensure your cabin is secure all around.

Either! We have designed the Cove to fit your garden, which means you can reverse the design to best suit your needs, with the door on the right and the side room on the left, as the images above show, or you can assemble it with the door on the left and the side room on the right.

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.
