Yellow Window is a design agency based in Antwerp, with studios in Paris and Lyon. It grew out of the studio of Axel Enthoven, who began his career designing buses at Van Hool, and was formerly known as Enthoven Associates. The agency became known for transport design, from the Bova Futura coach and the Mont-Saint-Michel shuttle buses to the VDL Jonckheere coaches and the refurbishment of the Thalys trains. Over time it has widened its work to product, service and policy design, for both private and public clients. It treats design as a balance between emotion and reason: reason leads when fitting out a train, emotion when designing a watch. Its work spans trains and buses, furniture, watches and medical equipment.
