1 World Trade Center, or the Freedom Tower, is the main building of the new World Trade Center complex currently under construction in Lower Manhattan in New York City. The tower will be located in the northwest corner of the 16-acre (65,000 m²) World Trade Center site, bound by Vesey, West, Washington and Fulton streets. Construction on below-ground utility relocations, footings, and foundations for the 1,368-foot (417 m) Freedom Tower began on April 27, 2006. On December 19, 2006, the first steel columns were installed in the building's foundation. Three other high-rise office buildings are planned for the site along Greenwich Street, and they will surround the World Trade Center Memorial, which is currently under construction. The area will also be home to a museum dedicated to the history of the site. The Freedom Tower's program includes 2.6 million square feet (241,000 square meters) of office space, as well as an observation deck, world-class restaurants, parking, and broadcast and antennae facilities, all supported by both above and below-ground mechanical infrastructure for the building and its adjacent public spaces. Below-ground tenant parking and storage, shopping and access to the PATH and subway trains and the World Financial Center are also provided.
An 80-foot-high (24 m) public lobby topped by a series of mechanical floors form a 200-foot-high (61 m) building base. 69 tenant floors rise above the base to 1,120 feet (341 m) elevation. Mechanical floors, two floors to be occupied by the Metropolitan Television Alliance, restaurants and observation decks culminate in an observation deck and glass parapet that mark 1,362 feet (415 m) and 1,368 feet (417 m) respectively — the heights of the original Twin Towers. A shrouded antenna structure supported by cables, engineered by Schlaich Bergermann & Partner rises to a total height of 1,776 feet (541 m), which is symbolic of the year the Declaration of Independence was signed (July 4, 1776). The tower rises from a cubic base whose square plan—200 feet by 200 feet—(61 m by 61 m) is almost as wide as the 208-foot (63 m) Twin Towers. The base is clad in more than 2,000 pieces of prismatic glass; each measures 4 feet by 13 feet 4 inches (1.21 m by 4.06 m) with varying depths. It has been designed to draw upon the themes of motion and light; a shimmering glass surface drapes the tower's base and imparts a dynamic fluidity of form whose appearance will reflect its surroundings. Just as the rest of the building, the base will serve as a glowing beacon. Cable-net facades on all four sides of the buildings, again designed by Schlaich Bergermann, measure 60 feet (18 m) high and range in width from 30 feet (9 m) on the east and west sides (for access to the restaurant and observation deck, respectively) to 50 feet (15 m) on the north side and 70 feet (21 m) on the south for primary tenant access, activate the building at street level. Though not occupied by office space, Freedom Tower's observation deck is set to be higher, at about 1,362 feet (415 m). Currently, the Sears Tower, Shanghai World Financial Center, and Taipei 101 have occupied floors higher than Freedom Tower. International Commerce Center, Chicago Spire, and the Burj Dubai will have roofs and floors higher than Freedom Tower's highest roofs and floors.
