Czechia.Prague,Villa Müller,Adolf Loos 1930. Villa Müller is Loos’s defining modern house in an era when rich, progressive industrialists were the source of modernist commissions. In Loos’s case the client owned a building company pioneering the use of reinforced concrete, so the house was a particularly relevant showcase. Outside, the Villa Müller is distinguished by its cubic shape, with flat roof and terraces, its irregular windows and its clean, white façade. Inside, the Villa Müller is at once more traditional and more original. The materials are warm, rich and comforting, and the furniture a deliberately eclectic mix of traditional styles.
