Detailed designs have been released for the three World Trade Centre buildings to stand on the eastern and southern edge of Ground Zero.
London-based Foster + Partners, Rogers Stirk Harbour + Partners and Japanese firm Maki and Associates have released drawings showing details such as a granite wall in the Maki building's lobby and a below-grade concourse shared by the three structures.
On the same day as the unveiling, the development firm leading the project – run by Larry Silverstein – will offer 70 separate construction bids for the office buildings.
The Foster + Partners website talks of the challenges that have been faced getting to this stage of the development for what will be a lasting memorial of the 2001 September 11 attacks.
"The rebuilding of the World Trade Centre site is one of the most important urban planning and architectural challenges of recent times," the firm says.
The firm had to sensitively consider security and safety in their design as well as the opportunity to redevelop areas of the local community.
The 79-story tower for 200 Greenwich (tower 2) will be 1,270ft tall, with an 80ft antenna on its peak. It will contain 60 office floors including a sky lobby, four trading floors and an office lobby, with sweeping views of the Memorial Park, river and city.
Richard Roger's 175 Greenwich Street (tower 3) will be the core of the trilogy – standing 1,155ft tall with 71 storeys above street level for retail, office and trading space.
