The research will address the relationship between architecture and time in the contemporary. Societies, cultures, heritages, resources, crises, and scientific innovations impose slowdowns and accelerations, memories and amnesias, movements, and stasis on the scenario with which design theories and tools are confronted. It will be investigated how precise devices of the project, from the development of critical thinking to the definition of the transformation process, from the structuring of the narrative system to real applications, accommodate the different shapes of time, synthesize them, and lead them back to projections to the future. From the setting of a design device, it is possible to mutate the time of action of architecture: to specify or expand it, to make it foundational or pervasive. Having analysed the main declinations of the relationship between time and architecture, the research will focus on a mode of relationship, a design device, and its concrete effects.
