Space exists with time. The site is located at Sejong-daero with the area size of 1,088 m2. It is a place where the meaning has accumulated through the interweaving of space, time, and public events. This design competition attempts to augment a new temporal layer of time. The layer of time in the space will intersect with the ground’s open space and underground’s contemporary space, and they will coexist in a different topographical demarcation. Thus, the shaped space in Saejong-daero will shine among citizens’ mind and life.
