Barcelona City Council is driving the BUITS (Empty Urban Spaces with Territorial and Social Involvement) Plan to provide a temporary social and community use for some of the municipally owned land sites that are currently in disuse.

This "empty space" plan invites the city's public and private non-profit organisations to propose a use or activity of general interest and temporarily run a site. Their proposals will be assessed and selected by an evaluation committee which will give special consideration to the programme's flexibility, its short-term and provisional nature, efficient self-management that keeps the facilities in good condition, and any positive social impact on the city as a whole. Therefore, an essential feature of the plan is the involvement of civil society in defining, installing and managing urban spaces.

Past projects included community gardns, meeting spaces and even parking biking.
