If you can’t afford to buy your own tropical island paradise, why not build your own? That is exactly what Richie Sowa did back in 1998, from over a quarter-million plastic bottles. His Spiral Island, destroyed years later by a hurricane, sported a two-story house, solar oven, self-composting toilet and multiple beaches. Better yet, he has started building another one! His ultimate goal? To build the island bigger and bigger and finally float out to sea, traveling the world from the comfort of his own private paradise.
