Seoul is a city built on innovation and commerce. Combine the two and you get Common Ground, the world’s largest container shopping mall. Developed by the design firm Urbantainer, the project was intended to revitalize unused land in the Gwangjin neighborhood. Now, 200 stacked, prefab blue containers stand on the site, helping connect the community with creativity. Independent boutiques in the Street Market and Market Hall areas lure shoppers, while gourmands head to the terrace restaurants and food trucks in the courtyard. A never-ending lineup of events is also on offer, from DJ nights and performances by emerging musicians to pop culture exhibits sponsored by Toy Republic.
