The original Spiral Island was (as its successor will be) built upon a floating collection used plastic bottles, all netted together to support a bamboo and plywood structure above. Located in Mexico, the original was 66 by 54 feet and was able to support full-sized mangroves to provide shade and privacy, yet also able to be moved from place to place by its creator as need with a simple motorized system.
Who hasn't wanted their very own private island? And what if you could build it with some friends and free recycled objects. Sound too good to be true? This guy has built not one but two!
