Built in 1797, it is seen as the "grandfather of skyscrapers", since its fireproof combination of cast iron columns and cast iron beams developed into the modern steel frame that made modern skyscrapers possible.
In 1852 Elisha Otis introduced the safety elevator, allowing convenient and safe passenger movement to upper floors.
In 2013 funding was confirmed to convert the derelict building into offices. ===Early skyscrapers=== In 1857, Elisha Otis introduced the safety elevator, allowing convenient and safe passenger movement to upper floors, at the E.V.
Otis later introduced the first commercial passenger elevators to the Equitable Life Building in 1870, considered by a portion of New Yorkers to be the first skyscraper.
Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s.
The building of tall buildings in the 1880s gave the skyscraper its first architectural movement, broadly termed the Chicago School, which developed what has been called the Commercial Style. The architect, Major William Le Baron Jenney, created a load-bearing structural frame.
The latter in turn was not surpassed until the Washington Monument in 1884.
Further developments led to what many individuals and organizations consider the world's first skyscraper, the ten-story Home Insurance Building in Chicago, built in 1884–1885.
The first steel-frame skyscraper was the Home Insurance Building, originally 10 stories with a height of , in Chicago in 1885; two additional stories were added.
A land boom in Melbourne, Australia between 1888 and 1891 spurred the creation of a significant number of early skyscrapers, though none of these were steel reinforced and few remain today.
In addition to the steel frame, the Home Insurance Building also utilized fireproofing, elevators, and electrical wiring, key elements in most skyscrapers today. Burnham and Root's Rand McNally Building in Chicago, 1889, was the first all-steel framed skyscraper, while Louis Sullivan's Wainwright Building in St.
Louis, Missouri, 1891, was the first steel-framed building with soaring vertical bands to emphasize the height of the building and is therefore considered to be the first early skyscraper. In 1889, the Mole Antonelliana in Italy was 167 m (549 ft) tall. Most early skyscrapers emerged in the land-strapped areas of Chicago and New York City toward the end of the 19th century.
This definition was based on the steel skeleton—as opposed to constructions of load-bearing masonry, which passed their practical limit in 1891 with Chicago's Monadnock Building. ::— Louis Sullivan's The Tall Office Building Artistically Considered (1896) Some structural engineers define a highrise as any vertical construction for which wind is a more significant load factor than earthquake or weight.

Wind pressure increases with height, so for very tall buildings, the loads associated with wind are larger than dead or live loads. Other vertical and horizontal loading factors come from varied, unpredictable sources, such as earthquakes. ===Steel frame=== By 1895, steel had replaced cast iron as skyscrapers' structural material.
Vanity height first appeared in New York City skyscrapers as early as the 1920s and 1930s but supertall buildings have relied on such uninhabitable extensions for on average 30% of their height, raising potential definitional and sustainability issues.
Since the 1960s, according to the CTBUH, the skyscraper has been reoriented away from a symbol for North American corporate power to instead communicate a city or nation's place in the world. Skyscraper construction entered a three-decades-long era of stagnation in 1930 due to the Great Depression and then World War II.
Early examples include Edificio España (Spain) Torre Breda (Italy). From the 1930s onward, skyscrapers began to appear in various cities in East and Southeast Asia as well as in Latin America.

Seven, dubbed the "Seven Sisters", were built between 1947 and 1953; and one, the Main building of Moscow State University, was the tallest building in Europe for nearly four decades (1953–1990).

He conceived of the glass façade skyscraper and, along with Norwegian Fred Severud, he designed the Seagram Building in 1958, a skyscraper that is often regarded as the pinnacle of the modernist high-rise architecture. Skyscraper construction surged throughout the 1960s.

The impetus behind the upswing was a series of transformative innovations which made it possible for people to live and work in "cities in the sky". In the early 1960s structural engineer Fazlur Rahman Khan, considered the "father of tubular designs" for high-rises, discovered that the dominating rigid steel frame structure was not the only system apt for tall buildings, marking a new era of skyscraper construction in terms of multiple structural systems.
Since about 1960, tubular designs have been used for high rises.
Most buildings over 40-storeys constructed since the 1960s now use a tube design derived from Khan's structural engineering principles, examples including the construction of the World Trade Center, Aon Center, Petronas Towers, Jin Mao Building, and most other supertall skyscrapers since the 1960s.
This becomes inefficient and uneconomic for buildings above 40 storeys tall as usable floor spaces are reduced for supporting column and due to more usage of steel. ===Tube structural systems=== A new structural system of framed tubes was developed by Fazlur Rahman Khan in 1963.
Concrete tube-frame construction was first used in the DeWitt-Chestnut Apartment Building, completed in Chicago in 1963, and soon after in the John Hancock Center and World Trade Center. The tubular systems are fundamental to tall building design.
This concept can be seen in the John Hancock Center, designed in 1965 and completed in 1969.

The first completed tall World Trade Center tower became the world's tallest building in 1972.
The tall Sears Tower stood as the world's tallest building for 24 years, from 1974 until 1998, until it was edged out by Petronas Twin Towers in Kuala Lumpur, which held the title for six years. ==Design and construction== The design and construction of skyscrapers involves creating safe, habitable spaces in very tall buildings.
LEED is a current green building standard. Architecturally, with the movements of Postmodernism, New Urbanism and New Classical Architecture, that established since the 1980s, a more classical approach came back to global skyscraper design, that remains popular today.
