1 World Trade Center

One World Trade Center will be a bold addition the the New York skyline. The design is an innovative mix of architecture, structure, urban design, safety, and sustainability.

From a 200-foot concrete base, the tower ascends sixty-nine stories, its edges chamfered back to form eight isosceles triangles, a perfect octagon at center. It culminates in a square, glass parapet at the crown. Its crystalline form will create a vibrant effect, as the light refracts in it like a kaleidoscope, changing throughout the day.   1 WTC will have 69 office floors, a restaurant, an enclosed observation deck, and a two-level broadcast facility, as well as below-grade shopping and access to public transportation.  

The cubic base of 1 World Trade Center with have a square footprint the same size as the footprints of the original Twin Towers. Clad in more than 2,000 pieces of  prismatic glass, the surface of the base will shimmer.  Surrounding the base will be a communal space at the plaza level has antecedents in Bryant Park, the steps at the Metropolitan Museum, and the base of Renaissance palazzos. In this space, people will gather, sit, relax, and reflect,around steel terraces shaded by trees and textured by granite cobblestones. Visitors to the WTC site will find the plaza an open, reflective space, one that connects the building with its surrounding neighborhoods.  

The crown of 1 World Trade Center is the 408-foot antenna, which will consist of a mast and a communication platform ring.  The mast will be protected by a one-of-a-kind fiberglass panel system that will resist wind loading, and create a protected maintenance area. At the base of the mast, a tetrahedral lattice ring will support media transmission equipment and brace eight radio-frequency transparent Kevlar guy cables that support the mast. When lit at night, a beacon at the top will send out a horizontal light beam that can be seen from miles away.  

With entrances on all four sides of the building, 1 World Trade Center has been designed to integrate the heterogeneous traffic of visitor and office tenants. Each portal will allow dedicated access to the concourse lobby and observation deck, office floors, and restaurant. The light-filled grand lobby will encircle the central core, a setting for changing art exhibits.
