The OBNI mobile unit (Non Invasive Neighbourhood Occupation), is a mobile device created for creative appropriation and the demand of the use of public spaces by neighbourhood organizations enabling the visibility of neighbourhood struggles through actions in both the space as well as the relationship among entities, becoming a driving tool within neighbourhoods. The OBNI mobile unit was created within the ID Barri BCN project “in/out” driven by Idensitat in collaboration with Elisava, collectively projected and designed by the students of the Design and Public Space Master’s Degree alongside members of Recreant Cruïlles under the supervision of the collective ‘Makea Tu Vida’.
