200 Greenwich Street - Tower 2
- Set to rise 1,254 feet in the air, 200 Greenwich Street will be the tallest of the Triplet Towers. British architect Lord Norman Foster designed the skyscraper. It will have 60 office floors, four trading floors, a sky lobby and a 65-foot-tall entrance lobby.

The Port Authority of New York and New Jersey and the city of New York will occupy two-thirds of the building, and the rest will be open to commercial tenants.
