“Contested Fronts” is an exploration of architecture’s role for commoning practices in ethnically and socially contested spaces. It focuses on the agencies of architecture’s ad-hoc technologies that contribute into conflict transformation by advocating reconciliation processes to go hand in hand with urban reconstruction processes. “Contested Fronts” concentrates on the agencies of ad-hoc technology’s materiality and use that encourage the emergence of collectives, with their members coming from areas across divides. Ad-hoc technology has to do with means of spatial engagement, of cartographic representation and of visual communication. It assists tactful organization of physical spaces and of events.
