Larry Silverstein said: “In the last four weeks alone, we’ve inked 200,000 square feet of new leases at 4WTC.

Visionary leaders recognize how top-quality sustainable, modern space delivers the best work environment and positively impacts the bottom line.”

The first tower to be completed on the 16-acre site, 4 WTC was designed by Pritzker-prize winning architect Fumihiko Maki to meet a LEED Gold standard of sustainability. A model of transparency and efficiency, the 977 foot (298 meter) tower contains 2.3 million square feet (213,680 sm) of light-filled, green and high-tech office space spread over 56 office floors.

4 WTC was designed to enliven and seamlessly integrate into Downtown’s streetscape, with a major concentration of retail – both at the street-level and in underground pedestrian concourses that lead directly to 11 subway lines and the PATH trains. 300,000 square feet (27,870 square meters) of destination retail will open at the World Trade Center on August 16. 4 WTC retailers include Eataly, Banana Republic and H&M.
