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.

19mm

Solid profile single Tongue and Groove for strength and durability. Great for small buildings with seasonal use in mind.

28mm

11mm Tongue and Groove

Our Standard flooring option which provides a durable, solid foundation and underfoot to the building.

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.

The Carmen Log Cabin Summerhouse

The Carmen Log Cabin Summerhouse is a versatile garden building offering a bright and welcoming space with tall glazed doors and two large opening windows. This garden building bridges the gap between a log cabin and wooden summerhouses, giving you thick and robust 19 or 28mm log walls and a modern pent style at a reduced cost.

This large summer house gives you the adaptability everyone looks for in a garden building; the Carmen is ideal as a family room, an entertainment room, a place to welcome guests, friends, and family.

The Modular Pent design will blend nicely in any garden as it is neither too striking nor too bland. It is thought of, designed, and built just right to look good and augment any garden.

One of the key features of this log cabin summerhouse is the modern windows and doors. These allow sunlight to enter and provide natural lighting and a spacious feel to the whole room. The long windows of the Carmen will also provide you with fantastic views of your garden. The wide double doors offer ease of access in and out of the summerhouse and can be left open to allow the warm summer breeze inside on a summer's day.

As with all of our log cabins, the Carmen comes with an 11mm tongue and groove floor and roof included with the option to upgrade to a 19mm floor for more intensive uses.

To completely protect the Carmen Summerhouse from the elements, you can opt for pressure treatment. The pressure treatment penetrates the wood, leaving you with a low maintenance building and requires fewer treatments at home, saving you money and hassle in the long run. A pressure-treated summerhouse is excellent for anyone looking for a building that will not take any effort to look after. It will stay looking great all year round, no matter the weather.

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.

We have a selection of different cladding options from the list below available on our buildings.

19mm - Solid profile Single T&G for strength and durability. Great for small buildings with seasonal or storage use in mind.

28mm - Solid profiles Single T&G for strength and durability. Great for medium to large buildings ideal for seasonal use.

With the Carmen 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.

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.

The building should be treated once fully assembled and within one month of receiving the product. All the treatments we supply ensure the building will only need to be treated once a year, but always consult the directions on the treatment that you have purchased. Pressure treated buildings don't need to be treated annually but may need to be topped up in its later life.

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.

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.
