This comprehensive publication presents for the first time ever the Czechoslovak Werkbund during the thirty years of its existence when it significantly modernized not only the field of housing and architecture, but also utilitarian objects, toys, and graphic and exhibition design. Its members were progressive representatives of architecture and design in interwar Czechoslovakia, such as Pavel Janák, Ladislav Sutnar and Hana Kučerová-Záveská. The Werkbund´s most important activities were the construction of the first Czechoslovak functionalist housing estates in Brno (Nový Dům, 1928) and Prague (Baba, 1932), and the House of Art Industry in the centre of Prague. This publication introduces the projects through renowned Czech and Slovak authors, and illustrates them with superb period photographers by Josef Sudek, Jaromír Funke, František Illek and Alexander Paul, among others.
