Bus stops, city toilets, benches, trash cans, infoboards ... Urban furniture in combination with outdoor advertising has had a defining influence on the public space of metropolises for more than 30 years. The project HACKING URBAN FURNITURE investigates the history, present and future of urban furniture in collaboration with artists, urban explorers, administrators, politicians, activists and researchers, in order to open up new horizons for the spatial public service design in the city.
