The Maldives, a small nation consisting of 1,200 islands is gradually disappearing as sea levels rise. In an attempt to save the place, their government has signed off on the development of several "floating facilities" like this one.
Dutch Docklands/Dutch Watervalley, makers of many floating homes, are the starry-eyed folks working with the Maldives government on this project and they intend on creating tiered—and yes, star-shaped—mini-cities which won't be bothered by rising sea levels.
There doesn't appear to be a timeline for the project yet, but I'm assuming they'll get around to completing it before the entire nation disappears. [Inhabitat]
