Ever wish the world was smaller? This group of more than 250 man-made islands was designed to resemble the entire world when seen from the air. The islands, which range from 250,000 to 900,000 square feet, can be bought by individual developers or private owners -- starting at $6.85 million.
The only way to get between each island is by boat...or yacht, given the clientele. A notable engineering feat: The project incorporates two protective breakwaters to protect the islands from waves, consisting of one submerged reef (the outer breakwater) and an above-water structure (the inner breakwater).
