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.

UPVC Doors & Windows

Now available on 44mm Cabins, upgrade to UPVC to give your cabin superior insulation, improved security and a gorgeous modern look. Includes multipoint locking, double glazing & chrome fixings. Available in either Smooth White or Woodgrain Textured Anthracite Grey, perfect for whatever style you're looking for. Please note the interior of your UPVC is white on either exterior colour

Key Features

Pent Roof with Fascia

The low-pitch angle of the roof, and added fascia frame, provides a modern and efficient top to this contemporary building.

Platform Base

The extended base not only provides a stable foundation for the Dojo E, but also creates a raised area ideal for seating.

Insulated Building

Double glazed windows and doors, as well as hybrid insulation materials in the walls, floor and roof, create an insulated envelope which reduces heat transfer.

Upgrades Available

Increase the durability of your building with pressure treatment, which also extends our guarantee, or personalise with uPVC windows.

Reversible Design

Suit this building to your garden and needs with the ability to reverse the position of the inset windows and doors to the left or right.

Cutaway Windows

The inset corner of the Dojo not only provides a unique silhouette, but also creates a protective roof overlap for the windows and doors.

Insulated Comfort

The insulated features of the Dojo ensure it’s comfortable all year round, designed for unpredictable UK weather. The hybrid insulation material ensures minimal heat loss and easy installation, meaning you’ll have a fully insulated building as soon as it is built. The double-glazed windows and doors add an extra seal and ensure the whole structure of the Dojo E is sealed for maximum comfort.
Insulated Comfort

A Modern Haven

The Dojo E offers you a sanctuary away from distraction: a place to relax and find peace in your own garden. The unique design of the Dojo embraces light and warmth, while offering a secluded area for privacy and comfort. The inset windows let sunlight illuminate the spacious interior, while the premium timber walls create a private area at the opposite end of the building, perfect for working on screens in the daytime. Finally, suit the setup to your needs with a fully reversible modular design.
A Modern Haven
15mm Tongue & Groove Exterior Cladding

The thick external cladding is designed to both add extra insulation and increase the strength and durability of the exterior - as well as giving a stylish vertical clad style.

EPS Insulation

The easy slide-in foam helps to insulate your building by containing heat within the interior, and preventing cold from seeping in.

11mm Tongue & Groove Interior Cladding

Like the outside the inside also uses Tongue & Groove timber, perfect for either a natural feel or ready to paint, stain or decorate however you choose.

Heavy Duty 27x44 Framing

At the heart of our premade panels is our extra strong 27x44mm framing, for durability, longevity and rigidity.

19mm Tongue & Groove Floorboards

Providing a flex free and stylish floor, our 19mm floor boards are perfect for longevity, holding heavy furniture for years to come. The outdoor decking area is also constructed from 19mm timber and allows for rainwater drainage.

EcoQuilt Multifoil Insulation

Using the same easy install EcoQuilt foil as the roof, this helps to prevent heat loss through the floor, keeping your building warm year-round.

38x38mm Pressure Treated Bearers

The base of your building is one of the most important parts, especially for preventing rot. That's why we use our strong, decay resistant 38x38mm Pressure Treated bearers to resist rot, fungus and insects.

EPDM Rubber Roof

Our durable rubber cover is designed to aid with water runoff, protect your building and is easy to install.

OSB Roofing Boards

The 11mm thick exterior boards are designed to make the roof easy to install, while providing strength, rigidity and protection against the elements.

EcoQuilt Multifoil Insulation

Using the same easy install EcoQuilt foil as the walls and floor, this aids in reducing heat lost through the roof, to ensure your building is warm in any season.

11mm Tongue & Groove Interior Ceiling Panels

Pre-assembled interior panels form a flat ceiling, as a stylish finish whilst also creating a cavity for increased insulation.

27x44mm Framing

Using the same extra strength framing from the walls, this forms the rigid inner core of your buildings roof.

More About the Dojo E...

The Dojo E is your very-own haven at home. A place where you can find a moment of peace, whether that’s relaxing in its warming interior or getting some quiet time to concentrate on the things that matter to you. Each part of this modern room is tailored to create a unique and calming building that you 

Insulated Design

Getting your piece of peace shouldn’t be a half-the-year thing. You want a building that you can come to when you need it, no matter what it looks like outside, and there should be comfort from the moment you step inside. That is what you’ll get with the Dojo E and its fully-insulated design. 

The wooden panels come with insulation built in, with layers of multi-foil insulation inserted between the exterior and interior timber boards. This means the moment it is built, it’s already insulated!

Ultra-modern Aesthetic

True modernity doesn’t just come from how a building works - but how it looks, too. The Dojo E’s enticing minimalist design boasts a beautiful square silhouette with straight-line fascias. The inset glazing only adds to the look, and the placement of the inset section can be reversed to suit your garden. Behind the facade, a smooth pent roof ensures consistent drainage.

Double-Glazed Windows

Only adding to the feeling of seclusion are the double-glazed windows and door glazing. Double glazing not only provides an additional layer of insulation, preventing heat loss and keeping the interior comfortable, but it also creates soundproof padding - separating you from the noise.

Tongue and Groove Timber

You’ll grow to rely on the Dojo E thanks to its reliable timber. All cladding, roofing and flooring is made from tongue and groove panels which click together for a seamless, smooth finish and a tight exterior seal. All this is attached to strengthened heavy-duty timber framing, with a frame thickness of 27x44mm. We also include a 10-year protective guarantee against rot, decay and insect infestation to ensure long-lasting use.

Rising Above

The Dojo is also separated from its surroundings on a raised timber platform. The platform keeps the main building safe from the elements, while also creating an extended area where you can sit, dine, or sunbathe. Please note that the platform is not a substitute for a properly constructed base.

Ideal Upgrades

You can make the Dojo your own with the unique upgrades available. Opt for pressure-treatment to improve the durability of the timber and extend your protective guarantee to 15 years. Or opt for UPVC glazing to make your building even stronger and even more stylish.

We provide delivery throughout the UK mainland, with most postcodes in England and Wales eligible for completely free delivery.

Thanks to the insulated design, which keeps it cool in summer and cosy in the winter, the Dojo E can be used as an extension to your home and in any room function you can imagine. A new office space, a place to relax, or a dedicated dining room - this building is your oyster.
While the building is constructed upon an extended timber platform it is recommended to provide a base for this. The base must be flat and provide some level of drainage to prevent the timber from becoming waterlogged. Our Fastfit Ecobase is a great solution and comes in any size you need. If you want to make it yourself, a concrete, gravel or paving base are all good options.
The panels of the Dojo E are embedded with multi-foil insulation which prevents heat transfer to and from the structure. The windows and doors of the Dojo are also double-glazed - with a vacuum trapped between two layers of glazing, also providing insulation.
Unplasticised polyvinyl chloride (uPVC) is a highly durable and low-maintenance building material alternative to timber. It’s used as window and door frames and is available as an upgrade to the Dojo E.
Pressure treatment is a chemical process applied to timber to improve its durability. During treatment, chemical preservatives are injected deep into the timber, which help maintain its strength and water-resistance. It is available as an upgrade to the Dojo E.
Yes, you can. This building is specially designed to include a number of useful insulating features, which create a strong “thermal envelope”. This means that there is a barrier all around the building that slows heat transfer - either keeping it in or out - so the interior stays cool or warm depending on the season and allows you to use it any season of the year.
This building is delivered in handy easy to assemble premade panels, with packs of solid timber for the exterior cladding and framing. Easy to lift and move around, these are ideal for moving down the side of a house fuss free.
We don’t offer an installation service, simply because all our buildings are designed to be easy to build. All you need is the help of a friend and some simple tools. With premade sections for the wall and roof, and easy fit-together tongue and groove boards for the floor, the building intuitively fits together and your Dojo E will come together in no time at all.
