Canadian company NOMAD Homes has produced a new concept micro-home that measures just 100 sq ft (9.2 sq m), ships as a flat-pack, can operate off-grid, and is said to be easy-to-build. The firm has turned to Indiegogo to raise funds for manufacturing, and eventually intends to sell the base version of the home for under US$25,000.
