This dissertation explores issues of habitability within psychiatric centres, as well as different spatial responses provided in the field, and within transitional spaces. As one of the specificities of psychiatry is the need to conduct observation, both for the patient and for the medical team, how can we combine privacy and observation within such a space, and what role can the architect and/or designer have in this process? This research explores the uses that supportive architecture can offer, from social vector to a medium for therapeutic activities or a tool for relief.
