•Double-glazing offers better insulation for all-year-round use and our best noise reduction for your building. Glass used is toughened for your safety and is fitted before delivery to you.

•Single-glazingis made 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.

Designed with You in Mind

The Derwent features an extra-high 6'2" door giving convenient access, but still has an overall building height of less than 2.5m to comply with planning regulations for the best of both worlds. With large glass doors and windows, you'll have a beautifully well-lit interior to spend your time in.

The building can also be used for many different purposes. Whether you're in need of an office to work from home in, a hobby and games room for making the most of your free time, or just a comfortable garden cabin to relax in with your family, the Derwent Log Cabin is perfect for you.

Multi-Purpose to Suit Any Need

What customer liked about the Derwent so far is the spaciousness. The reverse apex design serves to have you make use of the internal space.

With the many uses of the Derwent Log Cabin, your imagination is literally the limit. We have seen it transformed into a home gym, an office, and an entertainment room. The most creative one so far is the art room.

How would you design yours?

Multi-Purpose to Suit Any Need
Solid Interlocking Timber Construction

Solid Interlocking Timber Construction

The incorporation of tongues and grooves locks in every board in place. This gives you an easy to build but ultra rigid building. This is a far superior technique to that used for basic panel buildings, firmly fixing the timbers together and using their combined weight to give extra rigidity to the structure.

The 19mm standard walls are much thicker than the average garden shed. It has a strong and rigid construction so you can look forward to having your log cabin for years.

Pick Your Favourite Style

You have the choice between two fantastic-looking design variations, letting you select the window styling that's right for you. A single-glazed and double-glazed option is available in either style, so you can choose dependent on the level of insulation you need for your building.

Traditional Style (Georgian bars) – Premium and Standard options: The Traditional Style Derwent Log Cabin includes Georgian crosses placed upon the doors and windows to give the building a classic English feel. Choose Standard for single-glazed windows that are adequate for a seasonal log cabin, or Premium to upgrade to double-glazing that will help keep you warm in the Autumn and Winter months.

Modern Style – Premium and Standard options: If you prefer a more contemporary look, then the Modern Style is for you. This has a clean and minimalistic feel without Georgian bars, and once again offers the choice of Standard or Premium to suit your intended use.

Solid Under Foot

Solid Under Foot

If you have an everyday building like a home office in mind, the heavy-duty Premium floor option is ideal. Standard, on the other hand, is appropriate for seasonal domestic use.

Premium – heavy-duty floor: A Premium floor is the ideal solution for high-intensity usage – great for home gyms, offices, games rooms or log cabin with heavy furniture. Thick 19mm tongue and groove timber is used for the construction, giving added insulation properties against the cold, for cheaper and easier heating during the colder months.

Standard – regular floor: For more lightweight use we offer the Standard floor option, great for lighter intensity uses like log cabins and other living spaces with light furniture. With 11mm tongue and groove timber, this is a suitable economic option for many.

Basic – your bespoke DIY floor: For the DIY expert with specific requirements, we offer the Basic option. This supplies the building with the bearers only, letting you completely customise the base to your liking.

Sturdy Overhead

Tongue and groove roof boards: The roof panels for the Derwent are constructed from quality tongue and groove timber, just like the rest of the log cabin. This helps to increase the weather resistance of the building as well as its overall longevity, ensuring that it's built to last.

Increased strength: The roof purlins have been made stronger and thicker for your peace of mind, and to add the strength necessary to support the heavier roof covering options. As a result, the roof is suitable for roofing felt as well as being able to take the weight of roofing shingle for added protection from the elements. Make sure you take a look at our excellent roof weather protection options below.

Roof Options

Due to its position on the building, the roof is the most exposed and vulnerable to the weather, so it needs protecting as a result. Select one of our great roof weather protection options to ensure that the Derwent remains water-tight and in great condition from day one.

Premium weather protection: For the best weathering capability you can get, fit your new log cabin with our packs of Premium heavy-duty shingles in a selection of black, green or red. Roofing shingles are much thicker than our Standard weather protection option, giving extra durability and value to the building as well as adding style. These roofing shingles are waterproof, UV resistant, have an SAA fire rating and are very long-lasting.

Standard weather protection: Our Standard weather protection option gives you mineral felt that we use for our premium sheds. This is fast and simple to apply to the roof, and gives the cabin a sufficient level of defence against the weather.

Basic: Choose Basic if you intend to supply your own roofing materials to fulfil specific requirements.

Relax in Style

Derwent is particularly famous not on because of its spaciousness but also with that cosy home feel.

Comfort is something you will never miss out on regardless of the way you utilise your log cabin.

Choose Your Window Style Options

Choose Your Window Style Options

Georgian Style has window divisions that will give your log cabin the classic look.

SAN perspex come standard and for those in following a budget. But for a longer lasting overall protection, we recommend to upgrade your windows to double glazed.
