Kossmanndejong is an Amsterdam-based design agency that focuses on exhibition and interior architecture. The company was founded in 1998 by Herman Kossmann and Mark de Jong. Both are architecture graduates from the Technical University Delft. Since its inception, the agency has grown to include over 20 employees. A connection between content and imagination is what characterises the design approach by Kossmanndejong. It manages to do this while making complex design issues accessible to a broad audience and to transform them into intrinsic experiences. The agency combines a range of disciplines and media that enable it to tell spatial stories. Film, lighting and sound are indispensable media in generating experiences. The subjects of its exhibition designs vary from architecture, to children’s books, and from history to psychiatry, art for teenagers and microorganisms. In 2010 Kossmanndejong, in cooperation with Frame Publishers, has published ‘Engaging Spaces', a valuable and timeless sourcebook for everyone interested in the field of exhibition design.
