In this thesis I explore how design makes and unmakes citizenship through a collaborative independent project together with design student Théo Löfgren. I start out by looking at how the Swedish administrative levels of governance unmake citizenship by designing the Swedish citizens into customers. This has consequences since costumers have no obligations towards the collective, thus affecting sustainability on all levels (social, cultural, economical and ecological). Through my collaborative independent project I wanted to use design to critique that citizens are being designed into customers, as well as to create a design that promotes a citizenship of rights and obligations by co-creation. The result is a prototype of an interactive space called the Citizen Lab in which we (me and Théo Löfgren) use provotypes to create a discussion about the ‘customer citizen’ and the approach of participatory design to engage citizens in co-creation. The Citizen Lab was staged at the city library of Malmö (‘Malmö Stadsbibliotek’). In collaboration with the library and The Enforcement Authority (‘Kronofogden’) participants of the lab got to speculate about the future connected to problems and possibilities suggested by the collaborators. In the end the Citizen Lab proved to be a space in which participants could engage in co-creation as well as a place for us to try out our design and methods which were iterated on during the staging.
