Containers Direct are happy to offer the only 20ft office cabin on the market that is completely man portable - the ExpandaCom. Although other flat pack offices exist, like our 20ft CXO Office, they usually require cranes and specialist teams to assemble the unit after delivery. The ExpandaCom unit makes it the ideal solution for areas which are inaccessible to large vehicles, as each component is man portable, and a crane isn't required. Assembly is simple, and only manpower is needed to mount the panels and components into the steel frame and chassis - no specialist tools or equipment required!

Transport and delivery

All components of the 20ft self assembly office are packed to ensure that they are not damaged during transportation, loading and unloading under normal circumstances. The smallest transportation cube is achieved in this packing process, which allows us to offer much cheaper delivery rates compared to pre-assembled cabins.

Other flat pack offices

We offer a wide range of flat pack office containers, including smaller, man portable garden offices and larger options within our CXO range. While the CXO products aren't man portable, they provide excellent options for larger areas of modular office space with a range of options for external panels and interior fittings.
