Shipping container architecture uses steel shipping containers as structural elements for buildings. Containers are strong, widely available, and inexpensive building materials. They are modular in size, allowing multiple containers to be stacked or arranged in different configurations. Some advantages are low construction costs, short building timelines, and potential for difficult sites. However, containers can have issues with insulation, labor costs, and obtaining permits for residential use. Overall, shipping container architecture provides an affordable and flexible building method.
