Why the 6m size works
More usable storage space
With internal dimensions of 5699mm x 1985mm, the 6m model provides approximately 11.3m² of floor space. The extra length gives you significantly more room for larger storage requirements while retaining the demountable flat pack format.
Wide access through the short end
The double doors provide an 1850mm wide x 1900mm high clear opening. Positioning the doors on the short end leaves the full internal length available behind the entrance and gives you a wide opening for moving larger items in and out.

Why choose flat-pack containers
Flat-pack cabins arrive as compact panels, then assemble on site. They are ideal when access is tight, cranage is not practical, or you want a unit you can relocate later. Explore the full flat-pack range or use Quick Quote for the fastest advice and pricing.
Quick assembly on site
Build with basic tools in hours, not days, once your base is level. Compare sizes and layouts in our flat-pack container range.
Secure and site-ready
Galvanised steel panels with robust, lockable doors help protect equipment and stock. For controlled entry points, see the flat-pack security kiosk.
Delivered flat-packed for tight access
Compact delivery and man-portable panels suit restricted sites and back-of-house installs. Need a warmer internal environment? View insulated stores.
Demountable and relocatable
Reconfigure or move your unit as your site changes, without committing to a permanent structure. For short-term deployments, consider a pop-up container.
12 Month Guarantee
All flat-pack units include a 12-month fair wear and tear guarantee. If you have questions about suitability, access, or base preparation, contact our team or send details via Quick Quote.

Quick and easy assembly
See our assembly guide for the full step-by-step process. In most cases, installation is straightforward with basic hand tools and a sensible setup on site.
Before you start:
- Assemble on level, solid ground to avoid chassis twist and panel misalignment.
- Read through the full instructions first and lay out panels and fixings so you can work methodically.
- Hand tighten all nuts and bolts during initial assembly, then fully tighten everything once the unit is complete.
Tools typically required: 13mm spanner, 19mm spanner or sockets (or a socket set), and a screwdriver.
Safety and good practice: Take care when lifting panels and positioning the roof section, and assess the area for local hazards and access constraints. If the unit includes a door panel, keep the door locked while fitting and remove the taped keys before installation. Once assembled, re-check all fixings for tightness and keep the original packaging if you plan to demount, move and reassemble the unit in future.
