The proposed symposium aims at enriching the debate on the ways the conception of the built environment at different scales – from the single building to the city – can promote and protect the people’s health. We intend to discuss a renewed vision of the space for the care of the psycho - physical health which concerns not only the healthcare facilities but the whole built environment in which we live and work. The stress, because is posited to be at the origin of several of the most widespread and costly pathologies and also because it is correlated to the environmental conditions in which it is generated (and which can be planned) is assumed as the key topic. The proposed symposium intends to be an occasion of dialogue between two different disciplines both concerned with the socio-physical characteristics of the built environment: architecture and environmental psychology.
