How a giant hedge-fund hedge fund turned a 3,000-square-foot house into a $50 million home

A giant hedge fund that built the largest house in the United States on a hillside has used it to build a $500 million home in a suburb.

The project is the latest in a growing trend of mega-developments that have turned homes into office buildings and apartments.

The first such project, the $1.5 billion $100 million project to build the Trump International Hotel and Tower in Las Vegas, has seen construction start on the first two floors and end in December.

Other projects that have been built with giant office blocks include the $5 billion Oneonta Center for the Arts, a 20-story mixed-use building in the Bronx, New York, that was designed by Frank Gehry and is now under construction in downtown Manhattan.
