where you can buy your own private island,

 but here is another take on that idea, why not build your own island? that is what artists Catherine King and Wayne Adams decided to do some 25 years ago,

 currently moored off the coast of Vancouver Island
about 45 minutes by boat to the nearest town, their sprawling floating house is
called called 'Freedom Cove' the completely mobile island is made of 12
tethered sections that incorporates four greenhouses, living quarters, a
kitchen, workshop, art gallery, a lighthouse and even a dance floor, Adams
estimates the structure weighs in around 500 tons,
