International Style architecture

The International Style is the name of a major architectural style that is said to have emerged in the 1920s and 1930s, the formative decades of modern architecture, as first defined by Americans Henry-Russell Hitchcock and Philip Johnson in 1932, with an emphasis more on architectural style, form and aesthetics than the social aspects of the modern movement as emphasised in Europe. The term "International Style" first came into use via a 1932 exhibition curated by Hitchcock and Johnson, Modern Architecture: International Exhibition, which declared and labelled the architecture of the early 20th century as the "International Style". The most common characteristics of International Style buildings are said to be: i. rectilinear forms; ii. light, taut plane surfaces that have been completely stripped of applied ornamentation and decoration; iii. open interior spaces; iv. a visually weightless quality engendered by the use of cantilever construction. Glass and steel, in combination with usually less visible reinforced concrete, are the characteristic materials of the construction.

With the surge in the growth in cities in the first half of the twentieth century, particularly after World War II, the International Style provided an easily achievable style option for vast-scale urban development projects, "cities within cities", intended to maximize the amount of floor space for a given site, while attempting to convince local planners, politicians and the general public that the development would bring much-needed wealth to the city while, on the other hand, rejecting the proposal would lead to the development being taken to a different, competing city.

In Europe the modern movement in architecture had been called Functionalism or Neue Sachlichkeit (New Objectivity), L'Esprit Nouveau, or simply Modernism and was very much concerned with the coming together of a new architectural form and social reform, creating a more open and transparent society. The English term International Style originated from an exhibition in 1932 titled Modern Architecture: International Exhibition, curated by American architectural historian and critic Henry-Russell Hitchcock and recently graduated Harvard University philosophy student (and later self-taught architect) Philip Johnson. Commissioned in 1931 by the founding director of the Museum of Modern Art, Alfred H. Barr Jr, this was the first ever architectural exhibition held at the Museum of Modern Art in New York, USA. The original exhibition catalogue was then followed up immediately by the book titled The International Style, which was reissued in 1966 with a new foreword by Hitchcock.
