4 World Trade Center

72 stories of testament to the American spirit, the LEED Gold–hopeful 4 World Trade Center will boast 1.8 million square feet of office space, designed by the world–renowned architect Fumihiko Maki.

Located at the same southeastern corner of the 16-acre World Trade Center site as its eponymous predecessor, the similarities between the two buildings stop there. Unlike the original 9-story tower, the new 2.3 million-square-foot 4 World Trade Center is rebounding as a taller, stronger, and more impressive structure with a new address to boot: 150 Greenwich Street. The respectful, minimalist design by the Pritzker Prize-winning architect Fumihiko Maki is destined to become a lower Manhattan 21st-century landmark as 4 World Trade Center approaches its 2013 completion date.

Registered for Gold certification under the USGBC’s LEED for New Construction rating system, 4 World Trade Center was designed – and built – according to the highest of green building and building performance standards. Eighty percent of construction debris is on target to be recycled. Maki’s design optimizes natural daylight deep into the building’s structural core and smart indoor lighting technology automatically adjusts to the available levels of daylight. On cloudy days, an on-site hydrogen fuel cell powers steam turbines that provide electricity from wasted steam.

Office space at 4 World Trade Center will exist in two distinct floor plates. Low- and mid-rise floors (7 through 46) will feature 44,000-square-foot spaces in a parallelogram shape that mirrors the tower’s site plan. The high-rise floors (48 through 63) will be in the shape of a trapezoid of 34,000 square feet, triangulated from the lower floors to face 1 World Trade Center. Each configuration features a 45-foot span on the building’s west facade that faces over the 9/11 Memorial and is served by two elevator banks.

Upon completion, 4 World Trade Center will be the new home of the Port Authority of New York and New Jersey, which signed a 30-year, 600,000-square-foot lease with Silverstein Properties back in 2008. That deal was made in connection with the agreement where the parties swapped overall World Trade Center redevelopment rights with those for 1 World Trade Center.
