Gwangjang Market has a horizontal and linear structure due to modernization. The space above the arcade installed for convenience is desolate. The wine bar, Hidden hour, vertically expands the horizontally structured market. Hidden hour has a space in the form of a skip floor, and each area has a theme. The fragmented mirror symbolizes a break from daily life, and the dreamy hidden room is a space to forget everyday routines and hide in a deep place for a while. The rooftop, set against the skyline of Seoul, creates an atmosphere that lets guests breathe freely and escape from the fast pace of city life.
