20ft Office Container

There is nothing more durable than shipping containers. If you’re deciding between a container office or its plastic-coated equivalent, the container is the clear winner. Designed to endure a hard life at sea, containers are robust and versatile, serving effectively as both mobile and static offices. For instance, a 20ft container is made of 2.2 tonnes of solid steel and has a marine plywood floor supported by steel bearers, designed to carry up to 30 tonnes of cargo.

Our standard office, which can be purchased or rented, consists of anti-vandal windows with security shutters in galvanized steel and an anti-vandal heavy gauge galvanized steel security door. We can also customize them to your specifications. After installing the windows and doors, we insulate and line them with washable melamine, ensuring they look clean and brand new. The marine plywood flooring is suitable for most needs, but we can install any flooring you prefer. Our standard sizes are 20ft or 40ft, as these are the most mobile. 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.
