"We have designed a transparent and legible building which responds both to the architectural and social context of the area, and one which will make a fitting contribution to the New York skyline."
- Richard Rogers, Tower 3 Architect

Tower 3

Tower 3, also referred to as 175 Greenwich Street, will be the third-tallest building on the World Trade Center (WTC) site. Designed by Richard Rogers of Rogers Stirk Harbour + Partners, the tower will be situated at the center of the various buildings around the memorial.

The 71-story tower will rise 1,140 ft feet above street level and include 2.47 million rentable square feet of office space spread across 54 floors and five trading floors. The footprint of a typical floor will be approximately 200 feet by 198 feet. At ground floor level, the footprint of the building will be 50,000 square feet. At trading floor level - the widest level - this will increase to 63,000 rentable square feet.

175 Greenwich Street will have five retail levels - one on the ground floor, two below-grade levels, and two levels above the ground floor.

175 Greenwich Street will incorporate 44 passenger elevators serving the main part of the tower plus four freight elevators. The trading floors will be served by eight separate passenger elevators. The retail floors will be served by two passenger and two freight elevators. In addition, there will be two principal stairwells in the main part of the tower, increasing to four stairwells in the lower part of the building.

Building Systems

The tower will consist of a central concrete core - steel encased in reinforced concrete — and be clad in an external structural steel frame. Safety systems are planned to exceed New York City building code and Port Authority of New York and New Jersey requirements. Designed to the highest energy efficiency ratings, 175 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.
