The Office for Non-Efficient Development is a project designed to foster dialogue about free spaces that emerge in a city development process. It is an open space where people can let their imaginations wander freely, discover new things, and see the familiar in a new light. Free spaces are rare in Ulm. A major redevelopment is currently underway on the border between Weststadt and the city centre, creating new openings and bringing neglected places to light, like sunken islands that suddenly resurface. Our project offers time and space to engage intellectually with these islands.

We examine the spaces and areas that are becoming visible again as part of the current urban development process. We are developing artistic interventions in public spaces. The interventions within our project are created in collaboration between three artists/collectives from Ulm, who work with objects and installations, and three artists from Belfast, who work with theatre and performance.





I developed participatory interventions that activated the exhibition space to enagage people in “non-efficient” urban planning, creating an archive of requests, proposals, and imaginaries of how their city could be. I also developed workshops that engaged school classes more deeply into these urban imaginaries, such as a fictional real estate office for dream spaces developed for children between 9 and 12, a graffiti workshop for teenagers where the ideas of the smaller children where developed into slogans and then spray-painted on a construction site with the help of local graffiti artist Kiron Wagner, and an affective mapping workshop using excel as an efficient-non-efficient tool held by Gabriela Parra Sánchez.
