World Trade Center

The reconstruction of World Trade Center in New York has long been discussed, and finally, almost 5 years after the destruction of WTC on 11th of September a complete layout has been announced. Three new towers have been announced, 2 WTC, 3 WTC and 4 WTC, each tower with different architect. Construction is expected to start in 2007, and the whole new World Trade Center will be completed in 2012.A 25 meters high public lobby topped by a series of mechanical floors form a 61 meter tall building base. 69 tenant floors rise above the base to 341.4meter 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 415.1m and 417m respectively — the heights of the original Twin Towers. An antenna supported by a cable structure rises to a final height of 541.3 meters.Location - Freedom Tower is located in the northwest corner of the 64 500 square meter World Trade Center site, bounded by Vesey, West, Washington and Fulton Streets.Building Amenities - Observation decks, world-class restaurants, and the Manhattan Television Alliance (MTVA) broadcast and antennae facilities. All floors served by direct elevators. Cross-over elevator banks at floors 20, 29, 37 and 45. Ground floor contains a secure, 45-foot-high marble and glass entry lobby facing Greenwich Street, where access is limited to black cars and taxis. Loading dock with five bays accessible from Washington Street.Construction starts in January 2008, and the tower is on schedual to be topped out during spring 2009. Facades will be completed by summer 2010, and the tower will be fully completed by 1st Quarter 2011.Foster and Partners has designed a 76-story tower at 200 Greenwich. The tower, which will rise to 408 meters, is bounded by Greenwich Street to the west, Church Street to the east, Vesey Street to the north and Fulton Street to the south. It will contain 13 285 square meters of retail (8 825 square meters at or above street level), 60 office floors that total 213 676 square meters, four trading floors and a 20 meters high office lobby.Arranged around a central cruciform core, the tower comprises four blocks, containing light-filled, flexible, column-free office floors that rise to the 59th floor, where the glass facades shear off at an angle to address the Memorial Park. Extending the logic of the core, the volume of the tower is punctuated on all four sides by notches—elegantly breaking up the mass of the tower into four interconnected blocks. The upper floor contained within the summit provides an opportunity for spectacular multiple-height function rooms with sweeping views of the Memorial, the river and the city.Said Lord Foster, "We are pleased to unveil our design for Tower Two on the site of the World Trade Center, a building that symbolizes the renaissance of New York on the skyline while also re-establishing and reviving Greenwich Street at ground level. The crystalline top of the tower respects the master plan and bows down to the Memorial Park commemorating the tragic events that unfolded here. But it is also a powerful symbol of hope for the future. The dramatic height of the tower celebrates the spirit that has historically driven Manhattan to build tall, and the diamond-shaped top will be a crowning landmark on the city's skyline."Foundation work begins summer 2008, with construction start by spring 2009. The tower is on schedual to be topped out in December 2010. Facades will be completed by autumn 2011, and the tower will be fully completed by 2nd Quarter 2012.The 71-story 175 Greenwich tower, designed by Richard Rogers Partnership, will rise to 352 meters above street level. It is located on the site bounded by Greenwich Street to the west, Church Street to the east, Dey Street to the north and Cortlandt Street to the south. The tower will include 12 356 square meters of retail (6 781 square feet at or above street level); 54 office floors (195 096 square meters) and five trading floors.The design uses a structural load-sharing system of diamond-shaped bracing which helps to articulate the building's east-west configuration. All corners of the tower are column free to ensure that occupants of the office levels enjoy unimpeded 360-degree panoramic views of New York. The upper levels of the tower appear to straddle the lower levels—the "podium building"—which emphasizes the interlocking nature of the base with the upper part of the building. The three-level high lobby on Greenwich Street offers a "big picture window" onto the World Trade Center Memorial.Richard Rogers said,"175 Greenwich will occupy a hugely significant site in Lower Manhattan and in New York. We believe 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."Foundation work begins December 2007, with construction start by early 2009. The tower is on schedual to be topped out by spring 2010. Facades will be completed by early 2011, and the tower will be fully completed by 3rd Quarter 2011.The 61-story 150 Greenwich Street tower, designed by Fumihiko Maki and Maki and Associates, is located on the site bounded by Greenwich Street to the west, Church Street to the east, Cortlandt Street to the north and Liberty Street to the south. The 288.7 meters tall building will include 53 office floors (167 225 square meters), as well as five floors of retail, three of which are at or above grade.The tower has an abstract quality—minimal, light, cool in color and ephemeral, changing with the light of day. Seen from a distance, the building presents a unique angular profile at the crown effectuating the spiral composition formed by the group of four towers and looking back to the Memorial and the Freedom Tower. Facing Church Street is an 85-foot atrium offering a new dynamic urban experience by amalgamating the transit hall and retail into a single, identifiable whole, featuring multiple cascading floors that will enliven the street and become a symbolic feature of a revitalized World Trade Center.Said Fumihiko Maki, "The fundamental approach to the design of the tower at 150 Greenwich is two-fold—a 'minimalist' tower that achieves an appropriate presence, quiet but with dignity, becoming a tribute to the Memorial, and a 'podium' that becomes a catalyst in activating and enlivening the immediate urban environment as part of the revitalization of Downtown New York."Foundation work begins December 2007, with construction start by early 2009. The tower is on schedual to be topped out by spring 2010. Facades will be completed by early 2011, and the tower will be fully completed by 3rd Quarter 2011.
