Towns and cities have always been affected by continuous phenomena of ‘functional’ reuse and by processes of reuse that are very varied, especially if we consider service industry and ghetto transformations (including gentrification). What, on the other hand, do cases of temporary reuse suggest? It is that they can become opportunities for the inhabitants of a town or city, to ‘become political actors’. This prospect places reuses practices as interactive constructs (between parties of different types and between problem issues or sectors) back at the centre of the picture. It places them as interactive constructs and not systems in order to underline their character as a product ‘under construction’ and not a predetermined product, which generally means the predetermination of which parties are to be considered as actors, in which roles and for which purposes. On the other hand, reasoning in terms of constructs is a strategy to be considered effectively open with the interaction undetermined, during which (and not beforehand) the actors, the issues and the interests at stake and the relationships and the rules of the interaction, between one and another are defined.
