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.

The building also served as the headquarters of NYNEX and Bell Atlantic.  Kahn & Jacobs designed the building, which is the 61st tallest in New York. 1095 Avenue Of The Americas is a 630 ft (192m) tall skyscraper in New York City, New York.  The original facade was said to be designed to resemble the relays which were commonly found inside telephones of the time.  From 2006 to 2007 the tower received a $260 million renovation which upgraded the office space from Class B+ to Class A office space.  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.  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. <SEP>  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. 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. <SEP> The Quadrangle is a prominent sandstone building located within the University of Sydney Camperdown Campus.  Taking over 100 years to complete, the Quadrangle was designed and developed by numerous contributors including Edmund Blacket, James Barnet, and Leslie Wilkinson.  The original building included the Great Hall and was constructed between 1855 and 1862.  Construction on the quadrangle began in 1854, it had four sides by 1926, and was completed in the 1960s after several stages of development.  It comprises the Great Hall, MacLaurin Hall, Faculty of Arts office and the Nicholson Museum.  MacLaurin Hall was constructed from 1902-1904 and was designed by Walter Liberty Vernon.  The architectural style of the Quadrangle is gothic revival.  The building is mostly constructed of Sydney sandstone and is unique in the Australian architectural landscape.  At the time of its completion, the Quadrangle was ‘the largest public building in the colony.’  The Traditional Indigenous owners of the land on which the Quadrangle was built are the Cadigal and Wangal tribes of the Eora people.  The main entrance - constructed first along with the Great Hall - is underneath the clock tower, which holds one of only two carillons in Australia.
