In the 19th century, the regionalization of architecture became popular in South Tyrol. Similar to the "chalet" of the Swiss mountains, the Tirolerhaus became a symbol of alpine living, of the landscape, and of its traditions. Likewise, castles such as Prösels Castle were repaired, and prestigious country houses were built in keeping with the typical style of the region. This led to the import of architecture modules that are similar to the modular system of the Tirolerhaus.

The book outlines the historical development of building forms and their marketing as regional architecture through to developments in the 20th century. It accompanies an exhibition in the Tischlerhaus of Prösels Castle, and is also the first scientifically based treatment of the subject.
