Cookfox designed the tower, with Adamson Associates as executive architect, for the Durst Organization, led by Douglas Durst, with Bank of America as anchor tenant. Groundbreaking was on August 2, 2004, and it was completed in 2009. It has 55 stories above ground and three basements, on a base of seven and eight stories.
The architectural spire reaches 1,200 feet (370 m) and is lit by 368 LEDs. The roof is 945 feet (288 m) at the spire's location and 848 feet (258.5 m) at the north end. The facade is mostly a curtain wall of 8,644 insulated glass panels. The superstructure is steel and concrete, and the concrete mix is 45 percent slag.
It opened with LEED Platinum certification, described as the first U.S. office building certified platinum. A cogeneration plant provides up to 70 percent of its energy, a rooftop greywater system captures rainwater, and air filtration extracts 95 percent of particulates.
