We are an internationally operating architectural practice with roots in Vorarlberg. Our team of over 140 employees works on a wide range of tasks, makes decisions together and enjoys learning from each other. We avoid specialisation in order to remain alert, creative and innovative.

We are curious and questioning, researching and communicative. We treat resources and context with respect, cultivating and developing our passion for modern timber construction, where we have played a pioneering role from the very beginning. Sustainable, socially balanced and high-quality spaces with their own identity are a sincere need for us.

We recognise that responsibility in construction is changing and use the moment to break down conventional ways of thinking. Together, we develop contemporary solutions in an interdisciplinary process on an equal footing with our clients and craftspeople.

Dietrich Untertrifaller was founded in 1994 by Helmut Dietrich and Much Untertrifaller. Since 2017, they have been running the office together with Dominik Philipp and Patrick Stremler. After Helmut Dietrich’s resignation in November 2023, Dominik Philipp, Patrick Stremler and Much Untertrifaller will remain sole partners.
