Due to their wide range of functions, mixed-use complexes fit into the "15-minute city" concept, which is gaining ground in European cities. Under this idea, residents can work and find healthcare, education, shopping, dining, and entertainment within a 15-minute walk or bike ride from where they live. Residential areas are not separated from commercial zones. The reduced need for cars improves not only neighborhoods’ look and feel, but also the quality of life for residents.
