4 World Trade Center (also known by its street address, 150 Greenwich Street) is a skyscraper that is part of the new World Trade Center complex in New York City. It opened to tenants and the public on November 13, 2013. It is located on the southeast corner of the 16-acre (6.5 ha) World Trade Center site, where the original nine-story 4 World Trade Center stood. Pritzker Prize-winning architect Fumihiko Maki was awarded the contract to design the 978-foot-tall (298 m) building. As of 2013 it is the second tallest skyscraper at the rebuilt World Trade Center, behind One World Trade Center, although 2 World Trade Center and 3 World Trade Center are planned to surpass the building’s height upon completion. The total floor space of the building includes 1.8 million square feet (167,000 square meters) of office and retail space. The building’s groundbreaking took place in January 2008.

The original 4 World Trade Center was a 9-story low-rise office building completed in 1975 that was 118 ft (36 m) tall and in the southeast corner of the site, in Lower Manhattan, New York City. The building’s major tenants were Deutsche Bank (Floor 4, 5, and 6) and the New York Board of Trade (Floors 7, 8, and 9). The building’s side facing Liberty Street housed the entrance to The Mall at the World Trade Center on the Concourse level of the WTC. It was damaged beyond repair as a result of the collapse of the South Tower during the September 11 attacks and was later demolished to make way for the construction of the new skyscrapers, Four World Trade Center and Three World Trade Center. 4 World Trade Center was home to five commodities exchanges on what was at the time one of the world’s largest trading floors (featured in the Eddie Murphy movie Trading Places).

Groundbreaking took place in 2008. The building reached street level in November 2009. The safety cocoon was installed December 2010. The first glass was installed May 2011. In November 2010, three PureCell fuel cells were delivered at the World Trade Center site which together will provide about 30% of the tower’s power. The structural engineer for the building is Leslie E. Robertson Associates, New York City.

On February 16, 2012, one of the building’s construction crane cables snapped while lifting steel, causing the steel to fall 40 stories from the building, landing on a flat bed truck. No injuries were reported. Construction on the building eventually resumed after the accident.

On June 25, 2012, steel topped out at floor 72. Structural steel and concrete completed by June 1, 2013, followed rapidly by the removal of construction fencing in September 2013 and the building’s opening in November 13, 2013. Cost of construction of 4 World Trade Center was 1.67 billion USD, funded by insurance funds and Liberty bonds. The first tenants to move in were two government agencies, and as of July 2015, the building is 62% leased.

Layout and occupancy:

The above-ground portion of the building dedicated for retail use (which consists of the ground floor, the three floors immediately above the ground floor as well as the two floors below ground), will accommodate offices using two distinct floor shapes. From floors 7 through 46, the typical floor space is 36,350 square feet (3,376 square meters) in the shape of a parallelogram (which is designed to echo the configuration of the site). From floors 48 through 63 the floor space will be 28,000 sq ft (2,600 square meters) in the shape of a trapezoid, shaped so that it opens toward the tip of Manhattan Island and also triangulated to face One World Trade Center. The tower will include five levels of mechanical floors. The New York Power Authority selected UTC Power to provide 12 PureCell Model 400 fuel cells that will be used to provide electricity, water and heat. According to the developer, the systems combined will rank as one of the largest installations of fuel cells in the world. The upper floors of the building have no interior columns.

The Port Authority of New York and New Jersey (PANYNJ) plans to lease approximately 600,766 square feet (55,813.0 m2) in 4 WTC for its new headquarters. PANYNJ was formerly headquartered in 1 World Trade Center before it was destroyed. The Port Authority signed a 30-year lease. The lower levels of the building are used by retail businesses, including Eataly, and connects via an underground “retail and transportation concourse” to the PATH station. The city of New York also plans to lease 581,642 square feet (54,036.3 m2) of space, which is not in use yet, in the completed building.
