Bill Gates – Washington

As the third richest man on the planet, Bill Gates certainly wouldn’t choose a modest home like the rest of us mortals. In fact, the founder of the Microsoft empire decided to harness his technological know-how to build his dream home. The result materialized in the form of what Bill and Miranda Gates called “Xanadu 2.0.” It’s a residence that cost the couple a whopping $63 million, and where technology reigns supreme. What’s more, “Xanadu 2.0” is located just a stone’s throw from the sea, a luxury that only a businessman like Bill Gates can afford.
