2 World Trade Centre

2 World Trade Center at 200 Greenwich Street, features a sparkling glazed crystalline form and diamond-shaped summit that will create a bold addition to the New York skyline. Designed by Foster and Partners, the 88-story tower will be the second-tallest skyscraper on the World Trade Center site and in New York City. Located east of the proposed performing arts center and north of the WTC Transportation Hub,  2 WTC will rise to 1,349 feet.
The tower will contain five levels of retail; four trading floors; 60 office floors, including a sky lobby, that total 3.1 million rentable square feet; and a 67-foot-high office lobby. It will have a total of eight entrances: five entrances from street level, one below-grade entrances from the WTC Transportation Hub, and two from the retail area.

The first office floor begins at 278 feet above street level. A typical office area will vary in size from 41,000 to 45,000 rentable square feet of space. Trading floors will be 65,000 square feet.

The tower will consist of a central concrete core - steel encased in reinforced concrete - and an external structural steel frame. Safety systems will exceed New York City building code and Port Authority of New York and New Jersey requirements.

Arranged around a central cruciform core, the tower will be comprised of four blocks containing light-filled, flexible, column-free office floors that rise to the 59th floor, whereupon the glass façades will be sheared off at an angle to address the WTC Memorial Park. Giving the building its distinctive inclined summit as the second tower in the WTC Master Plan, 200 Greenwich Street's diamond crown also will act as a symbolic marker of the location of the memorial park when viewed from any location. The upper floors contained within the summit will provide sweeping views of the park, the river, and the city.
A continuation of Foster and Partners' investigation into the nature of the high-rise tower, 200 Greenwich Street will take structural, functional, security, environmental, and urban logic to a new dimension. The tower will be influenced by the geometry of the site, with the cruciform core providing the structural backbone as well as the key organizing diagram. It will accommodate the primary vertical circulation, with high-speed shuttle elevators rising to an intermediate sky lobby where the upper floors will be served by two further banks of elevators. It also will allow for cross-corridor circulation by providing excellent orientation at every level and opening views out across the office spaces.
Extending the logic of the core, the volume of the tower will be punctuated on all four sides by notches - elegantly breaking up the mass of the tower into four interconnected blocks. Toward the perimeter, the core will culminate in dedicated flexible zones that provide an opportunity to create staircases between floors and the possibility for double-height atria.
Connections with the city at street level will be reinforced with glass walls creating a visual relationship with the surrounding streets. The imposing double-height ground floor lobby will be connected at the Greenwich Street entrance to the subway, providing direct access to the underground infrastructure system. The lobby will rise in level along Vesey Street and includes a further connection with the transport system via escalators and a four-story shopping area connecting with Fulton Street and spilling out onto the Wedge of Light plaza.
