The law that entropy and disorder do not decrease in an isolated system also applies to relationships between people and cities. People constantly resist the planned city order and become disorderly, but there is no room in a city full of buildings and infrastructure. Therefore, people need an empty space to vent disorder, and that is the role of the open space of the city. In the past, Yeouido Square was a chaotic space where various activities overlapped on a huge concrete plate. However, as it was created as a park, there was a lot of order (symmetrical and regular arrangement) in it, and it became a space that was difficult to use in disorder. In order to regain the disorder of Yeouido Park, first, the order-making Pavement was erased and the trees were rearranged little by little to adapt to the entropy situation of the site. And so that the new floor can be a layer that has nothing to do with trees, I propose a band-type Pavement by overlapping connections of various strengths around the site. The elongated plate-shaped structure, placed between the relocated trees and the new floor, refracts the entropy flow on the ground once more and simultaneously introduces entropy from the city to the site. Yeouido Park could become a disorderly open space as countless different spaces and events occur when three independent layers of trees, floors, and buildings overlap.
