Christian de Portzamparc, Carnegie 57, New York City

Carnegie 57, is a new “ultraluxury” condo building, designed by French starchitect Christian de Portzamparc, on 57th Street across the street from Carnegie Hall, in New York.

The $1.3 billion skyscraper is actually the first major property development to come after the global financial crisis put hundreds of projects in the Big Apple on hold and upon its completion in 2013, will be the tallest residential building in the city, at 1,005 feet, eclipsing the Trump World Plaza.

There will be 136 apartments in the tower, above the 210-room Park Hyatt hotel which will sprawl over the first 20 floors. Gary Barnet, the project’s developer, seems confident that his tower will attract both design kudos and deep-pocketed buyers.
