Temporary use is a planning tool effectively bringing together various stakeholders: it engages an important number of municipal and private economic development agencies and property owners, as well as cultural organisations, to elaborate potential uses of existing infrastructure and resources. In the meanwhile, architects (and landscape architects, designers) also play a key role in the development of models for interim use and in the establishment of temporary spatial possibilities. Transforming empty properties to allow them adopt new uses offers advantages to all: owners profit with the renovation and preservation of the building, users access affordable work and living spaces, residents enjoy their revitalised neighbourhoods, merchants benefit increasing traffic and sales, and the design professions gain new work opportunities and expanded professional perspectives. The objective of the TUTUR project is to introduce the method of temporary use in urban regeneration to cities participating in the network.Temporary use is a planning tool effectively bringing together various stakeholders: it engages an important number of municipal and private economic development agencies and property owners, as well as cultural organisations, to elaborate potential uses of existing infrastructure and resources.

Temporary uses can be a source of life for neighbourhoods in order to promote a sustainable urban regeneration promoted by public administration and citizens. Temporary uses can accommodate any function, but in these days it would be essential to respond to needs related to youth employment, with co-working and start-ups, and cultural activities.
