Common characteristics of International style buildings are rectangular forms that have been completely stripped of applied ornamentation and decoration, visually weightless qualities, open interior spaces, and an overwhelming association with geometry. Glass, steel, and reinforced concrete are the characteristic materials of construction.

These three phenomena basically outlined the search for an economical utilitarian architecture, an architecture that would use the new materials and still appeal to aesthetic taste. Technology was key in this transition from tradition. The availability of cheap mass-produced iron and steel ultimately rendered masonry construction obsolete. The International Style was thus formed under the dictates that modern buildingsform and appearance should naturally grow out of and express the potentialities of their materials and structural engineering. A harmony between artistic expression, function, and technology would thus be established in an austere and disciplined new architecture. The International Style grew from a small group of brilliant and original architects who went on to achieve greatness in their field. The major figures include Walter Gropius, and Ludwig Mies van der Rohe of Germany. Gropius and Mies were best known for their str...
