![]() ![]() The style was fueled by the 1916 act to allow light and air to reach the streets. Phase 6- This phases is associated with the “setback” or “ziggurat” approach to skyscraper design. In this category three variants are recognized: the “isolated” tower, conceived as early as 1888 a “mounted” tower, dating about 1911, as exemplified by the Woolworth Building and a “set-back” tower, resulting from the rights provided by the revision of the zoning codes from 1916 onward. Phase 5- Dealing with the skyscraper in tower form. Phase 4- Starting in the late 1880s and characterized by a tripartite system of composition corresponding to the parts of a classic column with its base, shaft, and capital. Phase 3- This phase began in 1878 when the French mansardic mode gives way to a flat-roofed formula. This phase contained the necessary ingredients for the early skyscraper but the compositional features of Phase 1 still exist. Phase 1- A time before skyscrapers, dated roughly between 18, composed of buildings containing the essential elements of the skyscraper but not yet assembled into a single structure. According to Montgomery Schuyler, an influential architecture critic, the history of skyscrapers could be divided into seven distinct phases: Once the frame of a skyscraper was formulated, the exterior details could be borrowed from all different types of historical styles. The evolution of the skyscraper is divided into a series of periods defined by distinct architectural forms and methods of designs. The different styles of architecture that were introduced over the years gave the city’s skyline a new personality. The skyline has not only changed because of the height of the buildings, but also because of the new and unique styles of architecture being used to design the skyscrapers in NYC. Architects were forced to build even taller buildings than the ones that stood in the 19th century because of the limited space in Manhattan. Population growth in the developing urban area during the mid-19th century caused skyscrapers to rise in New York City. New inventions such as the elevator and electric lighting made it both technically and commercially possible to build skyscrapers. Technological improvements enabled the construction of fireproofed iron-framed structures with deep foundations. This change was sparked by the steel grid approach for the construction of multi- story buildings during the second half of the 19th century in the United States.
