This is the OPod Tube Tiny House by James Law Cybertecture designed and built out of concrete water pipes!
According to Business Insider, they measures just 100 sq. ft. and each tube costs about $15,000. They can be stacked and therefore be used as a temporary housing solution in places like shipyards, under highways, or even in-between buildings.
