Pehnt Wolfgang. Expressionist Architecture in Drawings

Van Nostrand Reinhold, 1985. — 115 p. — ISBN-13 978-0442273842.The freehand sketch is of particular importance for the understanding of Expressionist architecture - even more important, it might be argued, than the finished building. The book include more than 100 illustrations, paintings and drawing. Many drawings of this unique representative collection have never been published before.
They range from the crystalline Utopias of Bruno Taut and the almost Baroque exuberance of Hans Poelzig to the clear, formulaic lines of Erich Mendelsohn and the organic forms of Otto Bartning, Rudolf Schwarz and Rudolf Steiner. Among those whose projects did achieve realization are the young Mies van der Rohe and Walter Gropius and the master of the Dutch school, Hendrik Petrus Berlage, Michel de Klerk and Piet Kramer.
