Dietrich | Untertrifaller are outstanding representatives of the second generation of the New Vorarlberg Building School. Their buildings are always sensitive and, at the same time, confidently developed from the respective context; they display a spatial refinement, are formally disciplined, and feature finely nuanced materials. With a longstanding international reputation, the practice undertakes a wide spectrum of projects from its branches in Bregenz, Vienna, St. Gallen and Paris. Some of their latest works include the Omicron campus in Klaus, the Concert and Congress Center in Strasburg, and the University of Fine Arts in Nancy. This monograph presents the most important works of recent years in detail and provides a complete overview of the entire oeuvre of the architects, who are known for their efficient use of resources.

The Zacherlhaus is located in the heart of Vienna, just 180 meters from St. Stephen's Cathedral, and is one of the most important buildings created by the Otto Wagner School. It was built in the years from 1900 to 1913 and designed for its owner Johann Zacherl by Joesef Plecnik, who later taught at the Academy of Fine Arts in Prague and from 1925 worked on the urban renewal of Ljubljana. It was the first combined residential and commercial building of modern style in the historic inner city and is one of the best known buildings in Vienna. This generously illustrated, authentic publication documents the building and its thorough renovation, which will be completed in 2015; it includes contributions by experts on European architecture of the 20th century.
