4 WTC in May 2012, nearing its top-out point
4 WTC topped out in June 2012  

Developer Silverstein Properties began construction of World Trade Center Tower Four, also known as 150 Greenwich Street, in February 2008.

Designed by architect Fumihiko Maki, Tower Four completes Daniel Libeskind's master-plan concept by completing the descending spiral of skyscrapers that sends attention down to the National 9/11 Memorial plaza. Maki's design is minimalist and elegant, with its four corners each rising to varying elevations. Most notable is the significant setback on its western façade that creates the image of a single step.

Rising to a height of 72 stories (977 feet), the tower will house 1.8 million square feet of office and 146,000 square feet of retail space. It will feature 53 office floors, five stories of retail, and access to underground transit.

The innovative design of Tower Four was unveiled on September 8, 2006. As are all of the new WTC towers, it is planned to achieve the U.S. Green Building Council's LEED Gold certification when it opens in fall 2013.
