(b Skanderborg-Stilling, 12 March 1926). Danish architect. In 1957, having worked for C. F. Møller, he established a practice with Elmar Moltke Nielsen (b 1924). Friis, one of the few Danish architects to give rise to an identifiable school, had a decisive influence on Danish architecture during the 1960s and 1970s. He combined elements taken from Brutalism and Japanese domestic wooden architecture with traditional Danish components to create robust and exuberant buildings. Among his early family houses was his own in Århus (1958) and the houses at Permelillevej (1962), Århus. To Friis, the interaction of architecture and landscape was vital; in two summer houses at Helgenaes, rusticity is emphasized with rough concrete walls and turf roofs.
