All shipping containers are the same width, and most have two standard height and length measurements. As such, they provide modular elements that can be combined into larger structures. This simplifies design, planning, and transport. As they are already designed to interlock for ease of mobility during transportation, structural construction is completed by simply emplacing them. Due to the containers’ modular design, additional construction is as easy as stacking more containers. They can be stacked up to 12 units high when empty.
