This fantastic piece of real estate based in Florida Keys comes with three docks, a pool, sundeck, and its own saltwater moat. In addition to being off-the-grid location-wise, the island is completely self-sufficient, powered entirely by wind and sun.

Wayne Adams and Catherine King have spent the past 20 years building their own island near British Columbia. It is called Freedom Cove and has 12 floating platforms that run off of solar power. It is also a self-sufficient food garden. In winter, Wayne and Catherine collect rainwater for drinking and in summer, they use a nearby waterfall.
