4 World Trade Center

4 World Trade Center. It is a 978-foot (298 m) skyscraper located at 150 Greenwich Street on the southeastern corner of the World Trade Center site in Lower Manhattan. Designed by Pritzker Prize-winning architect Fumihiko Maki, the tower opened in November 2013 and is part of the master plan for the rebuilt site developed by Daniel Libeskind. The building is owned and developed by Silverstein Properties and serves as a modern office tower with significant government and financial sector tenants.

History

The site was originally occupied by the 9-story former Deutsche Bank Building, which was severely damaged during the September 11 attacks and later demolished in a complex operation completed in 2011. The rebuilding of this location was guided by the Libeskind master plan, with Larry Silverstein's development firm securing the necessary agreements and financing. Construction commenced in 2008, and the tower's steel framework reached its full height in 2012. It was the first office building on the rebuilt World Trade Center site to be completed and opened, with a dedication ceremony attended by then-Mayor of New York City Michael Bloomberg and other dignitaries.

Architecture and design

The architectural design by Fumihiko Maki emphasizes clarity, lightness, and sustainability. The tower's form is a simple, elongated parallelogram in plan, sheathed in a high-performance curtain wall of clear and fritted glass. This facade is designed to maximize natural light while minimizing solar heat gain, contributing to its LEED Gold certification. The design philosophy, often described as "permanent and changeable," creates a serene and minimalist aesthetic that contrasts with the more sculptural forms of neighboring towers like the Freedom Tower and the Santiago Calatrava-designed World Trade Center Transportation Hub.

Construction and features

The construction was managed by Tishman Construction, with structural engineering by Leslie E. Robertson Associates, the firm behind the original Twin Towers. The building utilizes a robust steel moment-frame system and a reinforced concrete core for stability. Notable features include a 65-foot-high lobby with art installations, advanced life-safety systems exceeding New York City Building Code requirements, and state-of-the-art telecommunications infrastructure. The tower's base integrates with the National September 11 Memorial & Museum plaza and connects directly to the PATH station and the Fulton Center subway complex.

Tenants and operations

The building's major anchor tenant is the Port Authority of New York and New Jersey, which occupies several floors. Other significant tenants include the Office of the Manhattan District Attorney, the Los Angeles Times' New York bureau, and financial firms like BNY Mellon and Jefferies Group. The ground floor houses retail spaces and a dedicated visitor center for the 9/11 Memorial. Building operations and management are handled by Silverstein Properties, emphasizing high-efficiency systems and tenant services, with security integrated into the overall World Trade Center campus protocols.

Role in the World Trade Center complex

As the southeastern cornerstone of the new World Trade Center, it plays a critical role in defining the site's eastern edge and street wall along Greenwich Street. Its completion helped reactivate the area's urban fabric and commercial vitality, serving as a catalyst for subsequent projects like 3 World Trade Center. The building's design and placement adhere to the commemorative and forward-looking vision of the Libeskind master plan, creating a dialogue between memory and renewal alongside the Reflecting Absence memorial pools and the St. Nicholas Greek Orthodox Church.
