<P0-S0> One Vanderbilt (also One Vanderbilt Place) is a skyscraper under construction in New York City on the corner of 42nd Street and Vanderbilt Avenue in midtown Manhattan, New York City. <P0-S1>  Proposed by New York City mayor Bill de Blasio and developer SL Green Realty as part of a planned Midtown East rezoning, the tower will stand next to Grand Central Terminal. <SEP> <P1-S0> The Flatiron District is a neighborhood in the New York City borough of Manhattan, named after the Flatiron Building at 23rd Street, Broadway and Fifth Avenue. <P1-S1>  Generally the Flatiron District is bounded by 20th Street, Union Square and Greenwich Village to the south; the Avenue of the Americas (Sixth Avenue) or Seventh Avenue and Chelsea to the west; 25th Street and NoMad to the north; Rose Hill to the northeast, and Lexington Avenue/Irving Place, Gramercy Park to the east. <SEP> <P2-S0> The Quadrangle is a prominent sandstone building located within the University of Sydney Camperdown Campus. <P2-S1>  Taking over 100 years to complete, the Quadrangle was designed and developed by numerous contributors including Edmund Blacket, James Barnet, and Leslie Wilkinson. <P2-S2>  The original building included the Great Hall and was constructed between 1855 and 1862. <P2-S3>  Construction on the quadrangle began in 1854, it had four sides by 1926, and was completed in the 1960s after several stages of development. <P2-S4>  It comprises the Great Hall, MacLaurin Hall, Faculty of Arts office and the Nicholson Museum. <P2-S5>  MacLaurin Hall was constructed from 1902-1904 and was designed by Walter Liberty Vernon. <P2-S6>  The architectural style of the Quadrangle is gothic revival. <P2-S7>  The building is mostly constructed of Sydney sandstone and is unique in the Australian architectural landscape. <P2-S8>  At the time of its completion, the Quadrangle was ‘the largest public building in the colony.’ <P2-S9>  The Traditional Indigenous owners of the land on which the Quadrangle was built are the Cadigal and Wangal tribes of the Eora people. <P2-S10>  The main entrance - constructed first along with the Great Hall - is underneath the clock tower, which holds one of only two carillons in Australia. <SEP> <P3-S0> 1095 Avenue Of The Americas is a 630 ft (192m) tall skyscraper in New York City, New York. <P3-S1>  It was constructed from 1972 to 1974 as headquarters of New York Telephone and has 41 floors. <P3-S2>  The building also served as the headquarters of NYNEX and Bell Atlantic. <P3-S3>  Kahn & Jacobs designed the building, which is the 61st tallest in New York. <P3-S4>  The original facade was said to be designed to resemble the relays which were commonly found inside telephones of the time. <P3-S5>  From 2006 to 2007 the tower received a $260 million renovation which upgraded the office space from Class B+ to Class A office space. <P3-S6>  The phone company moved its headquarters to the Verizon Building in the early 2000s, and sold off most of the building, retaining a condominium interest in floors 6-12, where Verizon maintained offices and a telephone exchange serving landlines in Midtown Manhattan. <P3-S7>  However, in 2013 the company moved its corporate headquarters back to 1095 Avenue of the Americas, following a sale of the upper floors of the Verizon Building.
