The architectural possibilities of the pitched roof seem almost unlimited and are all the more interesting for today's architects, in that the subject has been neglected for such a long time. By thematic plates, the publication shows the whole spectrum of possibilities that are opened up by pitched roofs. Their potential for the design of the outer façade of the building, and its relation to context and interiors is shown in a systematic fashion. Individual aspects are explored in depth in articles by renowned authors: Max Bosshard and Christoph Luchsinger, Nott Caviezel, Aita Flury, Hartmut Frank, Bettina Kohler, Marc Loeliger, Jacques Lucan, Martin Tschanz, and Christoph Wieser.
