    BillyOh Montana Log Cabin

    If you're looking to extend the living space of your home, the Montana Log Cabin is the garden building for you. It's an excellent alternative option to the more typical conservatories and brick house extensions, being much easier to construct and giving you a far superior value for money. The Montana Log Cabin is constructed from thick and solid tongue and groove timber boards, which are smooth to the touch and slot together without hassle for a simple installation in your garden. With a stylish front overhang, it's a unique-looking building that you'll be proud to own.

    One of the excellent features of the Montana is its customisability. You'll select your favourite between two designs: a traditional English, or contemporary Modern style. You can also choose the size of the building, the thickness of its floor timber, the roof protection and window glazing, and then put the icing on the cake with an attractive coloured treatment, if you wish.

    The Montana Log Cabin features an extra-high 6'2" door to give you convenient access. It also has a building height of less than 2.5m overall, to help comply with planning regulations and make your life a little easier. The large doors and windows featured in the design provide a beautifully well-lit interior to spend your time in.

    The Montana is very versatile, giving you the living space you need for whatever purpose. It's ideal if you're looking for a cosy, relaxing summer house or outdoor lounge to enjoy with the family; a hobby or games room for making the most of your spare time; or even a private and efficient workspace to serve as your home office.

    Designed with you in mind

    Designed with you in mind

    The Montana has been upgraded with extra-high doors to make getting into the building easier. The eaves height (the lowest point of the roof) has also been raised, giving you a greater average ceiling height.

    Spacious and bright: With a generous height of 6'2", the Montana's door opening accommodates the majority of adults, so you won't be bumping your head every time you enter. The windowed door and accompanying side windows provide the log cabin with plenty of sunlight during the day.

    Faster and easier: The Montana has an overall building height of just below 2.5 metres, giving it a greater chance of avoiding issues with current planning regulations. Nevertheless, we still strongly advise contacting your local area's council for information on this, as different council boroughs can vary.

    Customise to suit your needs

    The Montana lets you customise several important aspects of the construction, so you can get the exact building you want. The log cabin can be assembled in several different configurations, letting you place the doors and windows in the optimal position for your garden layout. We also give you the choice of building size, floor timber thickness, door and window style, glazing style and roof covering to create the perfect garden building for your requirements.

    If you have all-year-round use in mind, we recommend the premium 19mm floor for strength and durability, double-glazed Modern style doors and windows for insulation from the cold, and premium roof shingles to give the building long-lasting, effective weatherproofing. For a standard summer house only for use during the spring and summer months, single-glazed doors and windows will be sufficient, combined with the Traditional style to give a classic appearance. Then complete the building with roof shingles and premium paint for a great style that's personalised to your tastes.

    Customise to suit your needs
    Solid, interlocking timber construction

    Solid, interlocking timber construction

    The Montana is constructed with interlocking timbers, a traditional building method that gives additional strength to all of the boards. Compared to the technique used for basic panel buildings, this is a far superior method that firmly fixes the timbers in place, using their combined weight to make the structure rock solid.

    28mm tongue and groove timber is used for the walls of the building, a standard log cabin cladding that gives the Montana reasonable durability and insulation whilst still remaining affordable. With walls that are much thicker than the typical garden shed, it has a sturdy construction to give you peace of mind and longevity.

    Pick your cabin's style

    We give you the choice of two stunning building designs, letting you get the window styling that's right for you. Both styrene-glazed and double-glazing options are available in either style, so you can choose the level of insulation you need for your building. And with either style you'll also enjoy the unique feature of the Montana's front overhang, for an appearance that's full of character.

    Traditional Style (Georgian bars) – Premium and Standard options: The Traditional Style Montana Log Cabin features Georgian crosses upon the doors and windows, giving the building a classic British feel. Choose Standard for single styrene-glazed windows if you just have a seasonal summer house in mind, or Premium for an upgrade to double-glazing that will help keep you warm all through the year.

    Modern Style – Premium and Standard options: If you'd prefer a more contemporary design for your building, then the Modern Style is for you. This offers a clean, minimalistic feel without Georgian bars. Once again, you'll also have the choice of Standard or Premium to suit the intended use of your log cabin.

    The heavy-duty Premium floor option is ideal if you have an everyday building in mind, such as a home office for example. Alternatively, Standard is an adequate choice if you just need seasonal domestic use.

    Premium – heavy-duty floor: A Premium floor is the perfect choice for higher intensity usage. It's fantastic games rooms, home offices, home gyms or summer houses with heavy furniture. The construction uses thick 19mm tongue and groove timber, which gives you insulation against the cold weather, making the log cabin easier and cheaper to heat during Autumn and Winter.

    Standard – regular floor: We offer the Standard floor option for less demanding and frequent usage, suitable for lighter intensity purposes like summer houses and other living spaces containing light furniture. 11mm tongue and groove timber makes this is a suitable economic option.

    Basic – your bespoke DIY floor:

    If you're a DIY expert with specific requirements, we offer you the Basic option. The building will be supplied with the bearers only, letting you build the base completely from scratch to your liking.

    Sturdy overhead

    Tongue and groove roof boards: The Montana's roof panels are constructed from quality tongue and groove timber, consistent with the rest of the log cabin. This helps increase the building's weather resistance and its overall longevity, making sure that it's built to last.

    Increased strength:

    The roof purlins for the log cabin are strong and thick, giving the roof plenty of strength and support for your peace of mind. This also gives it the strength necessary to support more substantial roof covering, meaning it's able to take the weight of both roofing felt and roofing shingle for added protection from the elements. Ensure you take a look at our fantastic roof weather protection options.

    Protect the roof

    Protect the roof

    Due to its position on the building, the roof is the part of the building that's most exposed and vulnerable to the weather, so it needs good protection. Choose one of our great roof weather protection options to make the Montana water-tight and keep it in great condition from day one.

    Premium weather protection: For the very best weathering capability available, fit your Montana log cabin with Premium heavy-duty shingles, available in a selection of green, red or black. These are far thicker than our Standard weather protection option, providing the building with extra durability and value, as well as adding style. Our roofing shingles are UV resistant, water-proof, carry an SAA fire rating and are very long-lasting.

    Standard weather protection: The Standard weather protection option offers mineral felt, of which is used for our premium garden sheds. This is quickly and easily applied to the roof, giving your log cabin a basic level of defence against the elements.

    Basic: Basic is the option for you if you intend to supply your own roofing materials separately.

    Keep your cabin looking fantastic

    The Montana Log Cabin comes to you in a natural wood finish as standard. With a softwood construction, you'll need you to add preservatives to the building yearly to protect it from the weather and maintain its warranty. Be creative about it – choose your favourite base colour first and then add a complementary trim colour for an attractive design that's personalised to you.

    Premium treatment: The new addition to our treatment range is a beautiful selection of Premium colour paints, giving you much more choice of colour than ever before. Select the colour you love, whilst giving the best protection to the building you love.

    Standard treatment: Our Standard building treatment gives you a small selection of attractive, natural colours to paint your log cabin and protect it from the elements.

    Basic: Selecting the Basic option provides you with a blank canvas to apply your own choice of treatment products on to.
