Gwanghwamun Square in front of Gyeongbokgung is the historic square of Republic of Korea and a citizen square which represents democracy. It is proposed a new square that adapts to diverse occupancies and flows creating the possibility to flood large portions of the square during the weekdays when occupancies are low. The flooded areas act as reflected sceneries and reduce the walkable area rising the density of visitors which in return gives a more lively feeling even during the weekdays. The square dries as more space is needed.
