In this workshop seminar, students researched Iberian urban public space typologies through a series of ephemeral micro-interventions. The temporary physical interventions were not allowed to require more than 20 minutes to be assembled, documented, and disassembled; could not cost more than €10 in materials; were not allowed to hinder or block public space; and no traces whatsoever were to be left behind after disassembly. Works could be documented using photography and/or video. The micro-interventions had to achieve maximum impact using minimum means. “The quicker ‘n’ cheaper, the better.”
