Empty spaces which still haven’t found a new use, can find a temporary use in that ‘meanwhile’ of years and often decades, which passes between old and new use. The paper introduces six fields of investigation and study. The first section asks what temporary reuse means. The second part illustrates it with a diagram. The third part looks at case histories and international experiences. The fourth part looks at Milan as a field of investigation, design and experimentation. The fifth section presents design ideas that emerged from the research project ‘Temporiuso’ performed by the multiplicity.lab workshop of the Diap and by the associations Cantieri Isola and Precare.it. The sixth and last section tries to compare the work of experts and researchers on urban reuse and to raise some emerging issues.
