World Trade Center- Tower 4

Located on the southeast corner of the World Trade Center site, Tower 4 is a 72-story skyscraper designed by Pritzker Prize-winning architect Fumihiko Maki. This LEED-certified building anchors the heart of the new downtown and features a sleek unitized curtain wall system that defines its modern aesthetic.

Larson Engineering, Inc. was honored to contribute to this landmark project by providing structural calculations for the tower’s curtain wall system. In addition, our team engineered the steel façade spanning 50 feet across the podium’s transit hall—a dynamic space that offers direct access to nearly every subway line in New York City. Tower 4 stands as a symbol of innovation, resilience, and thoughtful design, and Larson is proud to have played a role in its realization.
