High-tech architecture, also known as structural expressionism, is a type of late modernist architecture that emerged in the 1970s, incorporating elements of high tech industry and technology into building design. High-tech architecture grew from the modernist style, utilizing new advances in technology and building materials. It emphasizes transparency in design and construction, seeking to communicate the underlying structure and function of a building throughout its interior and exterior. High-tech architecture makes extensive use of aluminium, steel, glass, and to a lesser extent concrete (the technology for which had developed earlier), as these materials were becoming more advanced and available in a wider variety of forms at the time the style was developing – generally, advancements in a trend towards lightness of weight.
High-tech architecture focuses on creating adaptable buildings through choice of materials, internal structural elements, and programmatic design. It seeks to avoid links to the past, and as such eschews building materials commonly used in older styles of architecture. Common elements include hanging or overhanging floors, a lack of internal load-bearing walls, and reconfigurable spaces. Some buildings incorporate prominent, bright colors in an attempt to evoke the sense of a drawing or diagram. High-tech utilizes a focus on factory aesthetics and a large central space serviced by many smaller maintenance areas to evoke a feeling of openness, honesty, and transparency. Early high-tech buildings were referred to by historian Reyner Banham as "serviced sheds" due to their exposure of mechanical services in addition to the structure. Most of these early examples used exposed structural steel as their material of choice. As hollow structural sections, (developed by Stewarts and Lloyds and known in the UK as Rectangular Hollow Section (RHS)) had only become widely available in the early 1970s, high-tech architecture saw much experimentation with this material. The style's premier practitioners include the following: Sir Michael Hopkins, Bruce Graham, Fazlur Rahman Khan, Minoru Yamasaki, Sir Norman Foster, Sir Richard Rogers, Renzo Piano, and Santiago Calatrava.
Background 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.
