Urban design is the process of shaping the physical setting of cities and villages. It deals with groups of buildings and the spaces between them, including streets, paths, gardens and squares. Urban design considers aesthetics and how the physical environment will be used. It requires input from multiple fields like engineering, ecology, history and transport planning. The best urban design involves interdisciplinary teams to create places that are good to live in, attractive to visit, establish community identity, reduce crime, and be socially and economically successful.
