In 2005 Yvonne Zimprich and Wolf Doser established their office for design in Trier. Their working environment encompasses the development of products and spatial concepts, with special regard to furniture design for the indoor and outdoor area. The challenge they set themselves when developing a concept is to reduce the product to its function and emotion. Thereby a consistent and honest design is as important as an economic realization. Numerous awards underline their work.
