In a world where life is increasingly defined by the spaces we inhabit, understanding interiors is essential to understanding ourselves.The Interiors Theory Primermaps the intellectual terrain of interior design and spatial experience, introducing readers to key concepts that shape how people occupy interior spaces.Organized into three parts, this book begins with foundational concerns, such as place, identity, materiality, and atmosphere, and then examines the boundaries and expertise of the discipline, before turning to critical and emerging topics like biophilia, virtuality, and social justice. Each chapter presents a focused literature review of a major theme in interiors theory, supported by key design precedents and suggestions for further reading. Drawing on a wide range of scholarship,The Interiors Theory Primeroffers a coherent framework for understanding interiors as a distinct, interdisciplinary field deeply embedded in the human condition.Accessible to students, useful to professionals, and provocative for scholars,The Interiors Theory Primerargues that the designed environments in which we live, work, and gather deserve greater attention-not only for their aesthetic and functional qualities but also for their powerful role in shaping contemporary life.
