The 'Base' Unit Details, Pricing, Finance


Insulated, Vapour protected, De-humidified, Heated.

Our completed shipping container base units are steel structures with door and window openings that are fabricated to suit the customer's purpose, garden layout and plans. The units are constructed with an insulated and vapour proof interior 'sandwich' for walls, floor and ceiling. Heating is designed to match the thermal efficiency of the structure across four seasons. A dehumidfier is supplied to mitigate the ingress of damp air.

Power Management, IT Connectivity

Electrical systems are designed under IET 18 and can be powered either by house supply  or alternative energy such as generator / solar / wind / battery. To ensure full flexibility our units are fitted with a large number of power and USB sockets. IT connection is easy to fit using different solutions to suit your project and its location in your garden. For extra 'fun' we are able to design the electrical system to accommodate voice control where Amazon, Google and Apple devices can be used.

Windows and Doors

The position of Windows and Doors is a matter of light, layout and positioning within your garden. These openings are framed in welded structural steel sections within which doors and windows are installed. Double glazing is standard, triple glazing options are available.

Walls and Floors

For our base units we opt for natural materials on both the floors and walls.

There are custom options depending on actual use and requirement with a huge range of panelling materials and style choices available.


Standard LED lighting allows for internal ceiling, external front wall and a single remote flood-light. 

Enhance your project with magical lighting options. Choose between high and low energy systems. Use colour and colour change effects through your mobile phone to wow your visitors! 

Premium Painting

Choose your internal colour scheme from our extensive range of premium paints. 

Specialist finishes are also available for a small extra charge e.g. chalk, metallic, matt or eggshell paint effects and lacquers.

Payment terms and conditions will be explained in detail during the purchase process. In outline, the Customer secures supply by paying a non-refurndable commissioning fee, which is 5% of the total price. This covers all preparatory design work, ongoing consultation work and the detailing of the build specification as well as a preliminary site visit. Once the build design and scheduling has been agreed with the Customer, a Production Agreement will be signed by both parties and a 45% Deposit will be required.  This will confirm the cancellation liabilities and obligations. Once the unit is completed, the Customer will be invited to conduct a pre-delivery inspection (PDI) and will be required to pay the balance before delivery to site.
