The selected projects presented in this booklet are mainly light, temporary, partecipatory, relational spatial devices. Their nature is between the installation and the performance, the playground and the event. They are microtransformations amplifying the more controversial, banal and anonimous quality of the places in their relations with the city. Each of the projects suggests a peculiar urban vision. For that reason there isn't a common functional programme to respect but an interpretation, a critical point of view to be unfolded. In the Studio 2008 / 2009 we focused on the space underneath the so called Viadotto di Corso Francia crossing the Olimpic Village in Rome.
