World’s Biggest and Most Expensive House

And what “the One” offers in true, mind-blowing abundance are some of the most luxurious, over-the-top amenities ever created in a private residence. Like the 42 bathrooms and 21 bedrooms, one of which is the 5,000-square-foot master suite with massive walk-in closets, adjoining two-story office and private pool. Above it is the 10,000-square-foot party-central skydeck with its own putting green.  Down on the third floor recreation level, there’s a four-lane bowling alley, a 64-foot-long indoor swimming pool, a wellness center with a vast gym, a full-service hair and beauty salon and a juice bar.
