If you can find a private island currently, it's probably remotely located and threatened by rising sea levels. Floating Private Islands take care of both of those issues, and provide loads of options as well. Designed by Dutch architect Koen Olthuis, each one is eco-friendly, and creates new underwater habitats for nearby sea life. And not only will you be able to choose what type of home or facility you want on your island, but you'll be able to choose where your island is located. So even if you're not in the market for your own private, floating island yet, it's nice to know they are out there, customizable, and ready when you are.
