Do we still need food markets when online grocery shopping apps are so convenient? Yes, we do! OPEN Metropolis (IV) "Overpass Market” is a new market proposal designed to utilize the "void" under the viaduct to fill the “need” for a vivid and interesting urban life. It is not only to fulfill the basic needs of life, but also to create opportunities for leisure, communication, and experience, and to satisfy the daily and real happiness of ordinary people.
