Real estate firm L&L Holding Company has invited 11 architectural firms to submit competing bids to design a $750m office tower at 425 Park Avenue in New York City, US.
The architecture firms include Atelier Christian de Portzamparc, Ateliers Jean Nouvel, Foster + Partners, Herzog & de Meuron, Kohn Pederson Fox Associates, Maki and Associates, OMA/Rem Koolhas, Renzo Piano Building Workshop, Richard Meier and Partners Architects, Rogers Stirk Harbour + Partners, and Zaha Hadid Architects.
L&L Holding Company chief executive David Levinson said: "We want to work with the best architectural minds out there, because we have some very important things to achieve and to deal with."
The new tower, spanning more than 35 storeys, will replace the current 559,763ft² building, which is located between 55 and 56 streets in Manhattan, New York.
After construction, the high-rise is expected to have a floor space of about 650,000ft² and offer views of Central Park on its upper floors.
By the middle of May 2012, L&L expects to choose a group of finalists who will be invited to create and submit their design concepts.
The proposals are to be completed and presented to L&L in late June and final selection of the architect will take place in October.
Work on the tower, which is expected to conform to LEED sustainability standards, is scheduled to begin in 2015 and complete by the end of 2017.
L&L partnered with Lehman Brothers to acquire the long-term lease on 425 Park Avenue in 2006.
