Bruno Reichlin ranks among the most eminent architectural theorists of our time. His writing and work as an architect are characterized by a recognition of architecture as its own language, a discipline in dialogue with a broad field of references, from literature, visual arts and film to technology.. This French-language volume brings together ten essays by Bruno Reichlin that address fundamental themes of 20th-century architecture: function, tectonics, and space. They are defined, decoded and examined through works by major figures of modern architecture—including Alberto Sartoris, Robert Mallet-Stevens, Ludwig Mies van der Rohe, Frederick Kiesler, Max Bill, the Italian architects group BBPR, and Carlo Mollino—as well as through topics such as the monument in modern architecture and building in the mountains. In contextualizing the examined buildings historically—on cultural, social, or technical levels—Reichlin always focuses his analysis on the work itself.Text in French.
