These are very tall habitable building which stands out clearly above its surrounding built environment and significantly changes the overall skyline of this particular city. [2] Originally buildings were made with a broader base to support the entire building. As time progressed and technologies evolved higher and thinner buildings started to become more practical. The crucial developments for modern skyscrapers were steel, glass, reinforced concrete, water pumps, and elevators. Steel and reinforced concrete allowed higher buildings to be built on a small patch of land. The water pumps were essential to pump water up to higher levels for the use of constructions and as well as utility. Primitive elevators of various designs had been used for centuries, and starting in the mid 19th century, steam-operated elevators were used to move materials in factories, mines, and warehouses.

Between 1872 and 1879 more than ten thousand construction permits were issued. Between 1871 and 1891 some $316,220,000 was poured into the construction of new buildings.
