USA's largest and most expensive house It took eight years and 600 workers to build 'The One'

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. 

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.
