From the cradle to the grave, humans live in an environment they have constructed. Nature, too, is shaped in most cases. Wilderness untouched by humans is becoming increasingly rare. This chapter addresses the question of how the built and shaped environment affects humans and how it can be designed to enable physical and psychological growth in the sense of salutogenesis. To this end, the basic principles of environmental psychology are first conveyed. These are then applied to the three central fields of the built environment: living, working/learning, and mobility. Specific environments are finally mentioned. In all these fields, important insights from environmental psychology emerge about the effects of design decisions and what recommendations can be derived for practice.
