Stefan Diez

Stefan Diez is a Munich-based industrial designer who creates products for the circular economy. Since founding his studio DIEZ OFFICE in 2002, Stefan has been at the forefront of transforming the ways in which contemporary products are developed and manufactured. The studio works across typologies such as furniture, lighting, architectural elements and accessories, bringing together technical expertise, creative experimentation and a rigorous commitment to sustainability.

Stefan’s approach to design is encapsulated in his 10 Circular Design Guidelines, a set of principles that outline how commercially successful products can be both environmentally and socially responsible. Together, these guidelines demonstrate how design can enable meaningful change across industry and society.

Over the course of his career, Stefan has created numerous award-winning products, forming long-term collaborations with internationally renowned manufacturers such as HAY, Vibia, Magis, Herman Miller, e15, Midgard, Thonet, Rosenthal and others.

In addition to his design work, Stefan has been involved in education since 2008. Since 2018, he has been head of the Industrial Design programme at the University of Applied Arts in Vienna, having previously taught at the the Karlsruhe University of Arts and Design, Lund University, and the Kunsthochschule Kassel.
