Developed by the Port Authority of New York and New Jersey – and managed, operated and leased by The Durst Organization, One World Trade Center is redefining Lower Manhattan’s New York skyline. Standing at a symbolic 1,776 feet tall, the architectural and engineering marvel is an ever-present symbol of renewal and hope.

Designed by renowned architect David Childs, of Skidmore, Owings and Merrill, LLP, One World Trade Center incorporates new architectural and environmental standards, setting a new level of social responsibility in urban design.

The 104-story building, a joint venture between The Port Authority of New York and New Jersey and The Durst Organization, is designed to be the safest commercial structure in the world and the premier c ommercial business address in New York. Currently One World Trade Center has leased 67 percent of its 3,000,000,000 square feet of office space which includes tenants: Condé Nast who is One WTC’s an chor tenant leasing nearly 1.2 million square feet to house its global headquarters, U.S. General Services Administration which has leased more than 270,000 square feet, global digital gaming company High 5 Games has leased more than 85,000 square feet, Tech advertising firm xAd has leased more than 86,000 square feet, and prominent financial services Moody’s has leased more than 70,000 square fee t bringing some of the world’s top companies to Lower Manhattan.

One World Trade Center has also attracted broadcast tenants CBS, NBC Universal-owned WNBC, WNJJ and PBS has relocated operations to the 408-foot-tall spire of One World Trade Center.

The New Standard in Design

The ultra-modern design of One World Trade Center is an innovative mix of architecture, safety and sustainability featuring column-free floors, nine-foot high, floor to ceiling, and clear glass windows for

spectacular unparalleled views. The building's simplicity and clarity of form are timeless, extending the long tradition of American ingenuity in high-rise construction. One World Trade Center will be a new visual landmark for New York and the United States.

One World Trade Center is designed to achieve LEED CS Gold Certification and its structure is designed around a strong, redundant steel frame, consisting of beams and columns. Paired with a concrete-core shear wall, the redundant steel frame lends substantial rigidity and redundancy to the overall building structure while providing column-free interior spans for maximum flexibility. The building incorporates highly advanced state-of-the-art life-safety systems that exceed the requirements of the New York City Building Code and that will lead the way in developing new innovative technology for high-rise building standards.

A New Level of Social Responsibility in Urban Design

Through unprecedented collaborations with technology and energy leaders throughout the world, One World Trade Center's design team used the latest methods to maximize efficiency, minimize waste a
nd pollution, conserve water, improve air quality and reduce the impacts of the development.

Taking advantage of the next generation of innovative energy sources, as well as off-site renewable wind and hydro power, One World Trade Center is slated to be both safe and environmentally friendly.
