Foster’s concept succeeded visions from Rem Koolhaas, Zaha Hadid and Richard Rogers (view all the proposals here). Construction is expected to begin in 2015, shortly after the completion ofFoster’s first U.S. residential high rise, which broke ground this week in New York.

Norman Foster stated: “Our aim is to create an exceptional building, both of its time and timeless, as well as being respectful of its context and celebrated Modernist neighbors – a tower that is for the City and for the people that will work in it, setting a new standard for office design and providing an enduring landmark that befits its world-famous location.”

“Clearly expressing the geometry of its structure, the tapered steel-frame tower rises to meet three shear walls that will be illuminated, adding to the vibrant New York City skyline. Its elegant facade seamlessly integrates with an innovative internal arrangement that allows for three gradated tiers of column-free floors. Offering world-class, sustainable office accommodation, the new building anticipates changing needs in the workplace with large, flexible open floor plates. Each of the three tiers – low, medium and high-rise – is defined by a landscaped terrace with panoramic views across Manhattan and Central Park. To maximize the Park Avenue frontage, the core is placed to the rear, where glazed stairwells reveal long views towards the East River, while at street level, there is potential for a large civic plaza with significant works of art.”
