Buying a container office: what to check

A portable cabin or container office is ready to use on arrival, so the questions are about layout and services. Check the internal size, the number and position of doors and windows, insulation, lighting and power sockets, and whether you need heating or air conditioning. For welfare and toilet units, plan the water supply and the waste connection or a waste tank. Jackleg cabins can be lifted on and off a truck on their own legs; other units need a crane or forklift to offload. Make sure the ground is firm and level, and know where power will come from before it arrives.
