Riehle+Assoziierte is an architectural practice based in Stuttgart and Reutlingen. We work on a wide range of public, commercial and private projects of various scales and typologies with a wholistic approach from the architectural idea to the constructed detail. Every project seeks for appropriate, convincing solutions that give simple answers to complex conditions. Our architecture is based on a robust set of ideas that give purpose to present situations and create quality places for people.

Hannes Riehle, Maximilian Köth and Heike Umlauf lead the offices in Stuttgart and Reutlingen. The projects are processed in individual, multidisciplinary teams to meet each project’s unique circumstances.

The ambition for an interdisciplinary and integrated project implementation is supported by a complementary network of associated specialist consultants to be able to develop and deliver projects as general planners and fully coordinated designers.


The office was founded in 1950 by Eugen Riehle and developed further to a nationally active practice by Wolfgang Riehle and his partners Gerhard Loew (until 2015), Jochen Kühl (until 2017) and Thorismuth Gaiser.

In 2014 Hannes Riehle and Maximilian Köth founded a branch of Riehle+Assoziierte in Stuttgart. Both met in 2005 studying at the University of Stuttgart and graduated with distinction in 2010. After working for a series of renowned practices in Germany and abroad, they combined their experience to work on their own projects mainly resulting from competition entries.

The retirement of Wolfgang Riehle from Riehle+Assoziierte at the end of 2018 completed the change of generations. Since 2019 Hannes Riehle, Maximilian Köth and Heike Umlauf are in charge of the offices in Stuttgart and Reutlingen.
