I can’t believe that I missed this, but there is a construction of artificial islands off the cost of Dubai that are loosely fashioned in the shape of the continents of the world. Pricing starts at $6.85mil and range up to $1.8bil and islands range in size from 250,000 sq. ft. to 900,000 sq. ft. with 164–328 feet of water in between each island. Not surprisingly, Richard Branson has already purchased an island.
