Growing up in a household of 4th-generation carpenters, Stefan Diez’s early bond with craftsmanship profoundly shaped his development as an industrial designer. Following family tradition, he trained as a cabinetmaker before studying industrial design under Richard Sapper at the State Academy of Fine Arts Stuttgart. Working with Konstantin Grcic for several years, Stefan founded DIEZ OFFICE in Munich after graduating in 2002.

From 2007 onwards Stefan was Professor for Industrial Design at the University of Arts and Design Karlsruhe, joining the School of Industrial Design Lund, Sweden, in 2015. Since 2018 Stefan Diez is Head of Industrial Design at the University of Applied Arts in Vienna. In 2008, DIEZ OFFICE fundamentally renovated and moved into the premises of a former joinery, the ideal platform for Diez’s distinct combination of hands-on experimentation and technical know-how. Led by curiosity and supported by a network of local craftsmen and specialists, DIEZ OFFICE is dedicated to transforming ideas into actual products with great diligence and proficiency.

Together with his team, Stefan Diez is particularly focussed on the potential of a circular economy, exploring a broad spectrum of everyday products whose raw materials can be recycled and integrated into a more sustainable material cycle. This approach has led to the creation of award winning furniture, luminaires and accessories, in collaboration with internationally renowned manufacturers like Rosenthal, Thonet, HAY, e15, Magis, Vibia, Viccarbe, Wagner and many more.
