Converting a 40ft shipping container into this secure, open space for a mobile office. Electrics fitted, plumbing and waste as well. All ready to be transported to customer and put in place to be used for years to come.

We have our own in house team who can design, convert, and construct not only containers but anything you may require in steel. This can be done to your own specification. It amazes us how many different uses Containers can be put to. We have over the years converted them into offices, schools, workshops, cafes, bars, and even used them in a children’s adventure park, as rifle archery ranges!

Shipping containers are the most durable of all storage/ shipping solutions. Whatever your project be it a container office, a Store, a Garden Room or a school classroom it will last you many times longer than its plastic-coated equivalent, the container is. It is designed to endure a hard life at sea, and is therefore far more durable, robust and versatile, than any of the available alternatives. For example, a 20ft container is made of 2.2 tonnes of solid steel and is supported by steel bearers together with a marine plywood floor. Both designed to carry up to 30 tonnes of cargo.

Our standard office, available to  purchase or rent, consists of anti-vandal windows with security shutters in galvanized steel and an anti-vandal heavy gauge galvanized steel security door. These can be customized to your specifications. Once the windows and doors have been installed we insulate and line the interior with washable melamine, ensuring they look clean and brand new. Although the marine plywood flooring is suitable for most needs, we can install any flooring you prefer. Our standard sizes of 20ft or 40ft,  are the most mobile, however, If required, we can create any size conversion you need. Air conditioning can also be installed to provide heating and cooling, making the workspace more comfortable.

10ft, 20ft, and 40ft shipping containers, all being used to create amazing extra space for these builds above. From just single containers to multiple containers being connected together to make large structures and very modern-looking buildings.
