A skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. 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. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
Louis Henry Sullivan was an American architect, and has been called a "father of skyscrapers" and "father of modernism." He was an influential architect of the Chicago School, a mentor to Frank Lloyd Wright, and an inspiration to the Chicago group of architects who have come to be known as the Prairie School. Along with Wright and Henry Hobson Richardson, Sullivan is one of "the recognized trinity of American architecture." The phrase "form follows function" is attributed to him, although the idea was theorised by Viollet le Duc who considered that structure and function in architecture should be the sole determinants of form. In 1944, Sullivan was the second architect to posthumously receive the AIA Gold Medal.
The Singer Building was an office building and early skyscraper in Manhattan, New York City. The headquarters of the Singer Manufacturing Company, was at the northwestern corner of Liberty Street and Broadway in the Financial District of Lower Manhattan. Frederick Gilbert Bourne, leader of the Singer Company, commissioned the building, which architect Ernest Flagg designed in multiple phases from 1897 to 1908. The building's architecture contained elements of the Beaux-Arts and French Second Empire styles.
The Home Insurance Building was a skyscraper that stood in Chicago from 1885 to its demolition in 1931. Originally ten stories and 138 ft (42.1 m) tall, it was designed by William Le Baron Jenney in 1884 and completed the next year. Two floors were added in 1891, bringing its now finished height to 180 feet. It was the first tall building to be supported both inside and outside by a fireproof structural steel frame, though it also included reinforced concrete. It is considered the world's first skyscraper.
The buildings and architecture of Chicago reflect the city's history and multicultural heritage, featuring prominent buildings in a variety of styles. Most structures downtown were destroyed by the Great Chicago Fire in 1871.
William Le Baron Jenney was an American architect and engineer known for building the first skyscraper in 1884.
Fazlur Rahman Khan was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center.
The Wainwright Building is a 10-story, 41 m (135 ft) terra cotta office building at 709 Chestnut Street in downtown St. Louis, Missouri. The Wainwright Building is considered to be one of the first aesthetically fully expressed early skyscrapers. It was designed by Dankmar Adler and Louis Sullivan and built between 1890 and 1891. It was named for local brewer, building contractor, and financier Ellis Wainwright.
860–880 Lake Shore Drive is a twin pair of glass-and-steel apartment towers on N. Lake Shore Drive along Lake Michigan in the Streeterville neighborhood of Chicago, Illinois. Construction began in 1949 and the project was completed in 1951. The towers were added to the National Register of Historic Places on August 28, 1980, and were designated as Chicago Landmarks on June 10, 1996. The 26-floor, 254-ft tall towers were designed by the architect Ludwig Mies van der Rohe, and dubbed the "Glass House" apartments. Construction was by the Chicago real estate developer Herbert Greenwald, and the Sumner S. Sollitt Company. The design principles were copied extensively and are now considered characteristic of the modern International Style as well as essential for the development of modern high-tech architecture.
The Bayard–Condict Building is a 12-story commercial structure at 65 Bleecker Street in the NoHo neighborhood of Manhattan in New York City. Built between 1897 and 1899 in the Chicago School style, it was the only building in New York City designed by architect Louis Sullivan, who worked on the project alongside Lyndon P. Smith. Located in the NoHo Historic District, the building was designated a New York City landmark in 1975 and has been a National Historic Landmark since 1976.
The Monadnock Building is a 16-story skyscraper located at 53 West Jackson Boulevard in the south Loop area of Chicago. The north half of the building was designed by the firm of Burnham & Root and built starting in 1891. At 215 feet, it is the tallest load-bearing brick building ever constructed. It employed the first portal system of wind bracing in the United States. Its decorative staircases represent the first structural use of aluminum in building construction. The later south half, constructed in 1893, was designed by Holabird & Roche and is similar in color and profile to the original, but the design is more traditionally ornate. When completed, it was the largest office building in the world. The success of the building was the catalyst for an important new business center at the southern end of the Loop.
S. R. Crown Hall, designed by the German-American Modernist architect Ludwig Mies van der Rohe, is the home of the College of Architecture at the Illinois Institute of Technology in Chicago, Illinois.
The design and construction of skyscrapers involves creating safe, habitable spaces in very high buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among the most complex encountered given the balances required between economics, engineering, and construction management.
The Rookery Building is a historic office building located at 209 South LaSalle Street in the Chicago Loop. Completed by architects Daniel Burnham and John Wellborn Root of Burnham and Root in 1888, it is considered one of their masterpiece buildings, and was once the location of their offices. The building is 181 feet (55 m) in height, twelve stories tall, and is considered the oldest standing high-rise in Chicago. It has a unique construction style featuring exterior load-bearing walls and an interior steel frame, providing a transition between accepted and new building techniques. The lobby was remodeled in 1905 by Frank Lloyd Wright. From 1989 to 1992, the lobby was restored to Wright's design.
Burnham and Root was one of Chicago's most famous architectural companies of the nineteenth century. It was established by Daniel Hudson Burnham and John Wellborn Root.
140 William Street is a 41-storey 152m tall steel, concrete and glass building located in the western end of the central business district of Melbourne, Victoria, Australia. Constructed between 1969 and 1972, BHP House was designed by the architectural practice Yuncken Freeman alongside engineers Irwinconsult, with heavy influence of contemporary skyscrapers in Chicago, Illinois. The local architects sought technical advice from Bangladeshi-American structural engineer Fazlur Rahman Khan, of renowned American architectural firm Skidmore, Owings & Merrill, spending ten weeks at its Chicago office in 1968. At the time, BHP House was known to be the tallest steel-framed building and the first office building in Australia to use a “total energy concept” – the generation of its own electricity using BHP natural gas. The name BHP House came from the building being the national headquarters of BHP. BHP House has been included in the Victorian Heritage Register for significance to the State of Victoria for following three reasons:
In structural engineering, the tube is a system where, to resist lateral loads, a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. This system was introduced by Fazlur Rahman Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office. The first example of the tube's use is the 43-story Khan-designed DeWitt-Chestnut Apartment Building, since renamed Plaza on DeWitt, in Chicago, Illinois, finished in 1966.
The history of structural engineering dates back to at least 2700 BC when the step pyramid for Pharaoh Djoser was built by Imhotep, the first architect in history known by name. Pyramids were the most common major structures built by ancient civilizations because it is a structural form which is inherently stable and can be almost infinitely scaled.
The earliest stage of skyscraper design encompasses buildings built between 1884 and 1945, predominantly in the American cities of New York and Chicago. Cities in the United States were traditionally made up of low-rise buildings, but significant economic growth after the American Civil War and increasingly intensive use of urban land encouraged the development of taller buildings beginning in the 1870s. Technological improvements enabled the construction of fireproofed iron-framed structures with deep foundations, equipped with new inventions such as the elevator and electric lighting. These made it both technically and commercially viable to build a new class of taller buildings, the first of which, Chicago's 138-foot (42 m) tall Home Insurance Building, opened in 1885. Their numbers grew rapidly, and by 1888 they were being labelled "skyscrapers".
The Breier Building, at 631–633 Main St. in Lewiston, Idaho, was built in 1923. It was listed on the National Register of Historic Places in 1986.
