The book *Architecture and Psychiatry* brings together the design strategies and technical recommendations essential for the programming, implementation, and acceptance of new structures, as well as the transformation—rehabilitation, renovation, and extension—of existing ones. It analyzes the relationship between architecture and psychiatry, which encompasses complex, hybrid architectural objects and practices that address both building construction and the attractiveness of space and their representations. What are the new approaches to psychiatry? How do they integrate into their surrounding urban or rural environment, taking into account the various constraints of existing structures, heritage, and technical, programmatic, safety, and quality requirements? How can we define the specific characteristics and needs of these services in terms of reception, environment, and the quality of outdoor spaces that promote the integration of people with mental health disorders? What are the new programmatic paradigms and the new constructive and technical dimensions of sustainable development that characterize the architectural design process? This book is intended for project owners, architects, and project managers, who will use it as a tool to aid in design and programming. It is also aimed at psychiatrists, healthcare professionals, hospital directors, patients, local elected officials, engineers and technicians, and all the numerous mental health stakeholders involved in the project design.
