#32: Bill Gates’ “Xanadu 2.0” in Medina, Washington
Worth $130 million
Bill Gates created Xanadu 2.0 as a long-term family residence that also showcased his love for technology and serene, nature-focused design. Built over several years, the home was meant to be both high-tech and calming, blending seamlessly into the surrounding landscape along Lake Washington.
Its roughly $130 million valuation comes from the estate’s enormous size, custom engineering, and coveted waterfront location in one of Washington’s most exclusive areas. The smart-home features were far ahead of their time, and the combination of privacy, acreage, and tech integration keeps its value exceptionally high.
