4 World Trade Center at 150 Greenwich Street will face directly onto the World Trade Center (WTC) Memorial Park from the west. Rising 977 feet from street level, it will be the fourth-tallest skyscraper on the WTC site. Designed by Maki and Associates, the 72-story tower is intended to assume a quiet but dignified presence at the site while also serving to enliven the immediate urban environment as part of the redevelopment efforts of downtown New York.
The podium of 4WTC consists of two retail levels below grade, ground floor, and three levels above grade. The remaining floors are set aside for commercial offices, totaling 2.3 million rentable square feet. One third of the office space is slated to become the new headquarters of the Port Authority of New York and New Jersey.
The tower portion of the building will accommodate office spaces in two distinctly shaped floor plates - 44,000 square feet and 34,000 rentable square feet. Both office floor plans contain a central core with a 45-foot span on the west side facing the memorial, as well as on the north and south. The east side has a 35-foot lease span. The project will also provide access to Wall Street and the central PATH terminal.
The building will feature many structural enhancements, including a reinforced concrete core and columns with steel girders and beams. Safety systems will be designed to exceed New York City building code and Port Authority of New York and New Jersey requirements. Designed in accordance with the highest energy efficiency standards, 150 Greenwich Street will seek to achieve the Gold standard under the Leadership in Energy and Environmental Design (LEED) by the U.S. Green Building Council.
