Seeking Excellence in Architecture.

The SL Rasch GmbH is an architecture and engineering company with its focus on lightweight and tensile structures, founded in 1980 by Dr. Mahmoud Bodo Rasch in Stuttgart, Germany. The multinational team pursues the Frei Otto's principles, which are based on an iterative work process of an interdisciplinary team closely accompanied by scientific research.

Who We Are.

The SL Rasch team is composed of qualified professionals with extensive experience and deep technical expertise, to manage the complete life-cycle of a project, ranging in complexity and size.

The brothers Rasch, Heinz (1902-1996) and Bodo (1903-1995), founded their design office in Stuttgart in 1926. Multi-talented and creative, they were at the vanguard of the modernist movement, which reflected in their architecture, interior- and furniture design, typography and book design. The result was a visionary spirit of invention with solution-oriented engineering skills of “modern construction”. 
The studio quickly developed into an important meeting place for the Stuttgart’s design and architecture scene. They were friends with many avant-garde artists such as Willi Baumeister, Oskar Schlemmer, Kurt Schnitters and Otto Dix. Additionally, they were in close-working cooperation with brilliant architects, such as Walter Gropius, Erich Mendelsohn, Bruno Taut and Martin Wagner. Even Mies van der Rohe moved into the Rasch studio for a short time.
The hanging houses and ideas of modular or airfilled building designs were revolutionary and unique in the architectural history of the 20th century.
Visionary engineering in 1967, during the course of his studies, Mahmoud Bodo Rasch worked with Frei Otto at the Institute for Lightweight Structures at the University of Stuttgart and, in 1969, at the Design and Development Bureau Atelier Frei Otto Warmbronn. Rasch led the construction of the new institute building (the tensile structure had originally been developed for the German Pavilion at Expo 67 in Montreal) and assumed the role of project leader for the convertible umbrellas, which Frei Otto had designed and built for the 1971 Bundesgartenschau in Cologne. Several joint projects and a close friendship resulted from this mentorship, and to this day SL Rasch follows the principles and methodologies that were established by them.
Frei Otto, the 2nd German Pritzker Prize holder, is the world’s leading authority on lightweight structures and has pioneered advances in structural mathematics and civil engineering.
