USA's largest and most expensive house

After nearly ten years of work, between design and construction, the largest and most expensive house in America is finally ready. Built-in an exclusive area of Los Angeles and renamed The One, the nearly 10,000 sq property remained top-secret for years until Architectural Digest managed to get through the gates of the mega property designed by architect Paul McClean and the interior designer Kathryn Rotondi. 

Surrounded by a 120m long jogging track, it took eight years and 600 workers to make the dream of the owner, film producer Nile Niami, a reality. Ceilings 8 meters high and great use of water, as evidenced by the entrance where in addition to a sculpture there is a bridge that leads inside the villa. Taking inspiration from the history of Los Angeles, McClean connected the inside of the house with the outside "to provide the quintessence of life in Los Angeles, but on a larger scale," she said. "To make the home feel livable, we separated the entertainment spaces from the living areas."

The house counts 42 bathrooms, 21 bedrooms, a master suite, a garage with 30 parking spaces and two car-displays, a four-lane bowling alley, a spa, a 30-seat cinema, a philanthropic wing for charity events, a sky deck and five swimming pools. For the interiors, Kathryn Rotondi has relied on brands from some of the most luxurious hotels in the world such as Aman, Bulgari and Baccarat. While the colour palette of the house is a tribute to Tom Ford's boutique on Rodeo Drive, a favourite of Niami and McClean. Also in the house, there is an impressive art collection, from Stephen Wilson to Niclas Castello, up to a collection of bespoke furniture by byShowroom. 

Following the new city ordinances, a house of this magnitude in Los Angeles will no longer be allowed, turning The One into something truly unique. Now all that remains is to find a buyer, the starting price is 340 million dollars.
