Dietrich l Untertrifaller Local roots, international presence. Sharing our vision with you. 7 Studios in Austria, Switzerland, Germany and France.

We are an internationally operating architectural practice with roots in Vorarlberg. We focus our architecture on the respectful use of resources, the development of socially balanced spaces and the appreciation of the cultural and architectural context. Since our founding, we have played a pioneering role in modern timber construction. Today, the office is managed by Helmut Dietrich, Much Untertr

ifaller, Dominik Philipp and Patrick Stremler and employs an international team of over 120 people at locations in Austria (Bregenz and Vienna), Switzerland (St. Gallen), France (Paris) and Germany (Munich). The entire spectrum ranging from large-scale buildings and urban structures through alterations of existing buildings to single-family homes defies specialization, constantly challenges and inspires creativity and an inquiring mind. Our international projects we often realise together with local offices and regional partners. A decisive factor in all our work is the resource-saving and appropriate use of materials, with a particular commitment to contemporary timber construction. We are well known for our expertise in design and construction and maintain this knowhow through relationships of dialogue and trust with clients, craftsmen and engineers. In course of lectures and in teaching we are glad to share our knowledge. Our innovative and sustainable buildings received numerous awards, including the Wiener Wohnbaupreis 2019 / Vienna Housing Award (Residential complex In der Wiesen Süd, Vienna), the Prix National de la Construction Bois 2017 (Sports Center Alice Milliat Lyon) and the State Award for Architecture and Sustainability 2017 (Elementary School Edlach, Dornbirn).

The construction sector accounts for nearly 40% of global CO₂ emissions and over 50% of waste. Regenerative architecture offers a direct path to mitigate this impact by prioritizing renewable, circular, and locally sourced materials like wood. This approach significantly reduces embodied carbon and conserves resources.

In our view, however, regenerative architecture offers pioneering solutions precisely because it combines traditional construction methods with modern technologies.

A recent example, Wood Art, illustrate the tangible benefits of this approach by using solid wood as a natural carbon sink.
At the College in Lamballe, France, prefabricated timber modules help minimize construction waste.

The REKA Holiday Village in Urnäsch, Switzerland, was built to the Minergie-ECO standard with locally sourced wood, reducing transport emissions.

With a roof area of 22,000 m² and built with 5200 m³ of construction timber, the TUM School of Medicine and Health in Munich is one of Europe’s biggest timber structures. Its distinguishing feature is a 150 metres long roof, which consists of 40 prefabricated hollow box girders

These strategies showcase a commitment to building in a way that serves both people and the planet.

Le Palais de la Musique et des Congrès de Strasbourg fête ses 50 ans !

Les festivités débuteront le vendredi 17 octobre 2025 avec un programme exclusif.

« Vous souhaitez découvrir avec nous le concept architectural du projet de rénovation et d’extension du PMC ? Nous vous emmenons faire un petit voyage architectural dans son passé récent. » – déclare Much Untertrifaller, qui participera à la cérémonie officielle en tant qu’invité d’honneur et qui partagera des informations sur le projet avec .

Leur conférence pour le grand public aura lieu le samedi 18 octobre à 15h00 en salle Curie.

Nous sommes honoré·e·s d’avoir contribué, avec .eu (aujourd’hui rey de crécy et Lucquet Architectes), à la préservation de ce bâtiment remarquable, notamment grâce à la récente rénovation de la salle principale et du foyer, qui a conféré à ce célèbre monument une clarté contemporaine et une cohérence spatiale.

Lessons in Bamboo: Lycée Tani Malandi, Mayotte
On the island of Mayotte, the Lycée Tani Malandi is an example of how architecture can integrate local materials and culture. In a joint effort with Austrian and French architects and local partners in Mayotte, we designed a campus for 2,000 students with classrooms, sports facilities, a library, a dining hall, and an on-site dormitory.

Clay, wood, bamboo, basalt—these ubiquitous natural materials used in this project emphasize the close relationship between the school and its surroundings. Bamboo façades are reminiscent of the woven fences of original Mahoran houses. Overhanging roofs and long pergolas in front of the classrooms are inspired by the verandas of traditional homes. The lime plaster on the gable of the gymnasium and the school refers to the name of the high school: „Tani Malandi“, which is the name of the white clay from the surrounding caves that is used for make-up at weddings or ritual ceremonies.
