150 Greenwich Street is the address for a new skyscraper to be erected as part of the World Trade Center reconstruction in New York City. The office building has also been referred to as World Trade Center Tower 4 and will be on the east side of Greenwich Street, across the street from the original location of the twin towers that were destroyed during the September 11, 2001 attacks. Noted architect Fumihiko Maki was awarded the contract to design the building which will be 947 feet (288 m) tall,^[1] which will make it the fourth tallest skyscraper on the World Trade Center site. ^[2] The total floor space of the building is anticipated to include 1.8 million square feet (167,000 square meter) of office and retail space.^[3] Excavation for the new building is expected to commence in 2007 and the building will be completed by 2011. The structural engineer for the building is Leslie E. Robertson Associates, New York City.^[4]

[edit] Planned Occupancy

After completion, 150 Greenwich is slated to become the new headquarters for the Port Authority of New York and New Jersey, which was formerly headquartered in 1 World Trade Center before it was destroyed. The building will dedicate the space on the lower levels for use by retail businesses and also provide access to an underground "retail and transportation concourse" which will be connected to the PATH terminal at the site.^[5]

[edit] Planned Space Layout of 150 Greenwich Street/World Trade Center Tower 4

Above the 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), the building will accommodate offices using two distinct floor shapes. From floors 7 through 44, the typical floor space will be 36,350 square feet (3,376 square meter) in the shape of a parallelogram (which is designed to echo the configuration of the site).^[6] From floors 46 through 60 the floor space will be 28,000 sq ft (2,600 square meter) in the shape of a trapezoid, shaped so that it opens toward the tip of Manhattan Island and also triangulated to face the nearby Freedom Tower. The tower will include five levels of mechanical floors.^[7]

[edit] Concept of design

The fundamental design approach of this building has two parts to it: to give a look of minimalism and quiet dignity in facing the World Trade Center Memorial while also allowing it to be a "podium", a means to assist in the redevelopment of the World Trade Center area.^[8]
