Brutalist architecture flourished from the 1950s to the mid-1970s, descending from the modernist architectural movement of the early 20th century. The term originates from the French word for "raw", as Le Corbusier described his choice of material béton brut, raw concrete.British architectural critic Reyner Banham adapted the term into "brutalism" (originally "New Brutalism") to identify the emerging style.
Brutalism became popular with governmental and institutional clients, with numerous examples in English-speaking countries (the United Kingdom, the United States, Canada, Australia), Western Europe (France, Germany, Italy), the Soviet Union, the Eastern Bloc (Slovakia, Bulgaria), and places as disparate as Japan, India, Brazil, the Philippines, and Israel. Examples are typically massive in character (even when not large), fortress-like, with a predominance of exposed concrete construction, or in the case of the "brick brutalists", ruggedly combine detailed brickwork and concrete. There is often an emphasis on graphically expressing in the external elevations and in the whole-site architectural plan the main functions and people-flows of the buildings. Brutalism became popular for educational buildings (especially university buildings), but was relatively rare for corporate projects. Brutalism became favoured for many government projects, tower blocks (high-rise housing), and shopping centres.
In its ruggedness and lack of concern to look comfortable or easy, Brutalism can be seen as a reaction by a younger generation to the lightness, optimism, and frivolity of some 1930s and 1940s architecture. In one critical appraisal by Banham, Brutalism was posited not as a style, but as the expression of an atmosphere among architects of moral seriousness. "Brutalism" as a term was not always consistently used by critics; architects usually avoided using it altogether. More recently, "brutalism" has become used in popular discourse to refer to buildings of the late twentieth century that are large or unpopular as a synonym for "brutal".
The term "brutalism" was originally coined by the Swedish architect Hans Asplund to describe Villa Göth in Uppsala, designed in 1949 by his contemporaries Bengt Edman and Lennart Holm. He originally used the Swedish-language term nybrutalism (new brutalism), which was picked up by a group of visiting English architects, including Michael Ventris. In England, the term was further adopted by architects Alison and Peter Smithson. The term gained wide currency when the British architectural historian Reyner Banham used it in the title of his 1966 book, The New Brutalism: Ethic or Aesthetic?, to characterise a somewhat recently established cluster of architectural approaches, particularly in Europe.
