Bill Gates – Xanadu 2.0

While not technically a celebrity in the sense that he doesn’t act or sing, Bill Gates is famous enough to be on this list. It’s really impossible to describe Washington’s lakefront estate, “Xanadu 2.0.” Here are some of the highlights. The 7-bedroom, 24-bathroom home spans over 66,000 square feet and includes 6 kitchens, a 2,100-square-foot domed library, a gym with a sauna, separate men’s and women’s locker rooms, a steam room, and a trampoline room, an indoor and outdoor pool with underwater sound, a man-made stream stocked with trout and salmon, and a theater.
