The successful combination of a regional building style of sophisticated simplicity with sustainable construction methods has made the architecture of Vorarlberg (Austria) a model for the rest of the world. This book presents particularly successful projects from recent years involving various building types and portrays their development from design idea to built detail. The documented structures by Cukrowicz Nachbaur, Christian Lenz, Oskar Leo Kaufmann + Albert Ruf, Hermann Kaufmann, Dietrich Untertrifaller, Baumschlager Eberle, Marte.Marte, and Martin Rauch place the focus on their energy strategy and formally ambitious construction methods. All of the plans and detail drawings were specially prepared for the book, which makes it easy to compare the projects.
