In urban planning, architecture, human geography, landscape architecture, and civil engineering, the term built environment, or built world, refers to the human-made environment that provides the setting for human activity, including homes, buildings, zoning, streets, sidewalks, open spaces, transportation options, and more. It is defined as "the human-made space in which people live, work, and recreate on a day-to-day basis." The built environment is most relevant in the fields of architecture, landscape architecture, urban planning, public health, sociology, and anthropology, among others.
