Bill Gates’ impressive Lake Washington mansion is so renowned that it even has its very own Wikipedia page. The stunning 66,000-square-foot property is iconic for a variety of reasons. Not only is it worth $125 million, but it even uses technology in its design. Would you expect anything less? 

Gates built the property over a span of seven years, giving it the name “Xanadu 2.0.” Not only does the home have seven bedrooms, but it has a huge amount of bathrooms too – 18.75 to be exact. There’s also plenty of outdoor space to entertain, including decking and Bill’s own personal dock.
