born in Stuttgart, Germany; graduated 1987 from Technische Universität Stuttgart.
1983 he founded LABFAC as a collective with Bernd Hoge and Jochen Hunger in Stuttgart, and in 1987 opened the studio LABFAC Paris with Nicolas Michelin. Time, openness, adaptability and context-specificity are important themes in his work, as apparent in early projects including the design for a temporary roof for the Arena in Nîmes, and the École nationale supérieure d'Art de Limoges.
