High-tech architecture

High-tech architecture was originally developed in Britain, with many of its most famous early proponents being British. However, the movement has roots in a number of earlier styles and draws inspiration from a number of architects from earlier periods. Many of the ideals communicated through high-tech architecture were derived from the early modernists of the 1920s. The concepts of transparency, honesty in materials, and a fascination with the aesthetics of industry can all be traced to modern architects. High-tech architecture, much like modernism, shares a belief in a "spirit of the age" that should be incorporated and applied throughout each building. The influence of Le Corbusier, Walter Gropius, and Mies van de Rohe is extensive throughout many of the principles and designs of high-tech architecture. Some of the earliest practitioners of high-tech architecture included the British architecture group Archigram, whose members frequently designed advanced futuristic buildings and cities. On the most influential of these was Peter Cook's Plug-in City, a theoretical mega structure designed around the detach-ability and replacement of each of its individual units. The concept of removable and interchangeable elements of buildings would later become a widespread characteristic within the high-tech style. Less direct precursors included Buckminster Fuller and Frei Otto, whose focus on minimizing construction resources generated an emphasis on tensile structures, another important element in many high-tech designs. Louis Kahn's concept of "served" and "servant" spaces, particularly when implemented in the form of service towers, later became a widespread feature of high-tech architecture. Other projects and designs that contained or inspired elements common across the high-tech style include the Archigram member Mike Webb's concept of bowellism, the Fun Palace by Cedric Price, and the Walking City by Ron Herron, also a member of Archigram. These theoretical designs, along with many others, were circulated widely in British and American architectural circles due to their examination by Reyner Banham. These conceptual plans laid out the ideas and elements that would later go on to be hugely influential in the works of prominent high-tech architects like Norman Foster and Nicholas Grimshaw. ==Characteristics==

It is designed to blend in with the neighboring Singapore Expo complex.High-tech buildings often incorporate a range of materials reminiscent of industrial production. Steel, aluminium, glass, and concrete are all commonly found in high-tech structures, as these elements evoke a feeling of being mass-produced and widely available. Not all high-tech designs are made to accommodate truly mass-produced materials, but nonetheless seek to convey a sense of factory creation and broad distribution. Tensile structures, cross beams, and exposed support and maintenance elements are all important components found in high-tech designs. A focus on strong, simplistic, and transparent elements all connect high-tech as a style to the principles of engineering. The engineer Anthony Hunt was hugely influential in both the design, choice of materials, and ultimate expression of many of the earliest high-tech buildings in Britain, and as such many of these designs are suffused with a focus on the aesthetics of engineering and construction. Buildings built in the high-tech style often share a number of characteristic layout elements. These include an open floor plan, a large central area serviced by many smaller maintenance spaces, and repeated elements which either can be or appear to be able to be detached and replaced as needed. Spaces or elements dedicated to service and mechanical components like air conditioners, water processors, and electrical equipment are left exposed and visible to the viewer. Often these spaces are placed in large service towers external to the building, as in the Lloyd's building in London by Richard Rogers. The Lloyd's building also has offices designed to be changed and configured as needed by the shifting and removal of partitions – creating a flexible and adaptable interior environment that can be changed to meet the needs of the building's occupants. This theme of reconfigurable spaces is an important component of high-tech buildings. The HSBC Building in Hong Kong, designed by Norman Foster, is another excellent example of a high-tech building designed to be changed over time according to the needs of its users. Its use of suspended floor panels and the design of its social spaces as individual towers both place emphasis on the new approach to creating and servicing an office building. The high-tech style is often interpreted as glorifying technology and emphasizing the functional purpose of each element of the building. These designs incorporate elements that obviously display the technical nature of the components within them, creating a sense of honest, open transparency. The Centre Pompidou in Paris, by Renzo Piano and Richard Rogers, exemplifies the technicality and focus on the exposure of service elements. The externalization of functional components is a key concept of high-tech architecture, though this technique may also be applied to generate an aesthetic of dynamic light and shadow across the facade of a building. Color also plays an important role in the decoration of high-tech buildings, as various colors can be used to represent different service elements or to give the building the appearance of a set of architectural diagrams. As of 2016, recent Structural Impressionism has two major trends: braced systems and diagrid systems. Both structural systems have the structural support elements visible from the outside, unlike many postmodern architecture buildings where most structural elements are hidden in the interior. The braced systems have strong exterior columns connected by "heavy" cross bracing elements. The diagrid system consists of a lattice of "light" diagonal elements and horizontal rings forming triangles, without vertical columns. == Goals ==

High-tech architecture attempts to embody a series of ideals that its practitioners felt were reflective of the "spirit of the age". Concerns over adaptability, sustainability, and the changing industrial world drove a shift in the way that many architects around the world approached the challenge of designing buildings. Norman Foster's HSBC Building was specifically designed to be built over a public plaza, so as not to take up more land in space-conscious Hong Kong. Minoru Yamasaki's World Trade Center had centered around a five-acre, raised public plaza, completely devoid of cars, so pedestrians could walk freely through the complex. Additionally, the World Trade Center had led to the construction of a brand new PATH station, serving the rail commuters coming from New Jersey into New York. This approach to building, with the architect having just as much responsibility to the city surrounding their building as the building itself, was a key theme of many structures designed in the high-tech style. The appropriate utilization and distribution of space is often an integral component of high-tech theory, and as such these ideals are often found in concert with practical concerns over habitability and practicality of design. High-tech architecture has generated some criticism for its forays into home building and design, an issue it shares in common with Modernism. Many of the houses designed by high-tech architects were never inhabited by anyone other than themselves or their close relatives. Many outside observers found the high-tech style's focus on industry and expression of services to be antithetical to comfort and home living. Norman Foster's housing at Milton Keynes was never particularly popular, and other high-tech designs were seen as uncomfortable or awkward to live in. == Examples ==
