This book comprehensively lays out the knowledge base required for architectural practice and education at a time when artificial intelligence (AI) algorithms are shaping the way architects think. Architects with a desire to retain their creative role in the design of buildings and urban spaces must understand and articulate the theoretical bases of their work and what it can achieve. This book provides a clear structure and outline of both the functional and procedural theoretical base for architects to employ in their work. It offers an intellectually rigorous basis that allows architects to understand the evolution of architecture through history as well as the advocacies of individual architects. It provides them with the scope of architectural theory necessary for designing for the future. The book can be a valuable reference for researchers and professionals interested in architectural theory and allied fields.
