I’ve seen a lot more discussion about shipping container homes lately in Mexico, the US and Jamaica. Basically the idea is that where countries are net importers they end up with an oversupply of shipping containers. The containers are weather tight and well built so they can be utilized as the structure for inexpensive housing. The basic shipping container is only 8 feet by 40 feet so a single shipping container is tight. However, they can be combined or utilized as only one piece of the overall structure. They can also be stacked on top of each other.
