REFILL wants to upscale and diffuse the urban practice of temporary use of vacant buildings and land and intensify the temporary experiences by investigating the various action beyond temporality. As such, the REFILL network’s objectives is to go one step beyond what has been achieved previously and to contribute to a wider quest for new governance models to support temporary use:1) Exchange and evaluation of local supporting instruments: to upscale and distribute temporary use through good practices, to explore on new challenges, and to enhance the participation and co-creation of policies in relation to this topic; 2) Ensure long lasting effects of temporality: to enable continuous development of temporary use initiatives, to deal with experimental development in relation to vacant plots and their permanent destination, and to capture the dynamics created around temporary use; and, 3) Build a more flexible, collaborative public administration: to engage with the dynamic forces in the urban society, the search for more integrated and horizontal working procedures, to rethink the roles of civil servants, to adapt legal frameworks, to enhance the role of politicians in this policy shift and to promote social innovation in these changes.
