The communicative object, similar to a movable furniture piece transfers the act of dish-washing to a public level and therefore invites people to gather, work collectively and appropriate public space. It reminds of a market stall as a place for communication and exchange. Inefficient, chaotic, loud and as funny as possible, the acts of cleaning, repairing or maintaining give back their value to everyday objects and show their multiple potential. The dish-washing integrates the visitor and invites them to take part. The Mobile Dishwasher can be borrowed from the Professorship of Architecture and Design.
