Book excerpt: ***WINNER OF A NAUTILUS 2018 SILVER MEDAL BOOK AWARD*** Innovations in Behavioural Health Architecture is the most comprehensive book written on this topic in more than 40 years. It examines the ways in which healthcare architecture can contribute, as a highly valued informational and reference source, to the provision of psychiatric and addictive disorder treatment in communities around the world. It provides an overview of the need for a new generation of progressively planned and designed treatment centres – both inpatient and outpatient care environments – and the advantages, challenges, and opportunities associated with meeting the burgeoning need for treatment settings of this type. Additional chapters address the specifics of geriatric psychiatry and its architectural ramifications in light of the rapid aging of societies globally and provide a comprehensive compendium of planning and design considerations for these places in both inpatient and outpatient care contexts. Finally, the book presents an expansive and fully illustrated set of international case studies that express state-of-the-art advancements in architecture for behavioural healthcare.
