The "Encyclopedia of Designed Space" offers a comprehensive analysis of human interventions in the environment. It highlights how cities, landscapes, and other physical elements are shaped by conscious and often usage-oriented design. The publication examines the complex interactions between natural conditions and social, political, and cultural influences that affect the design of our living space. With an interdisciplinary approach that combines planning, humanities, and cultural studies, nearly 40 elements of our physical environment are analyzed exemplarily. The presentation is not only textual but also visual, to clarify the multifaceted relationships and their impacts on design. This encyclopedia is a valuable work for anyone interested in the mechanisms of spatial design and its historical development.
