The intervention recovers the traces of the land, pushing nature’s vital force to emerge from in between the urban pieces in order to recreate a natural ecosystem that provides great quality of public open space for the community. In the beginning, there was land, water and sun. We propose to recreate this vital cycle, the essential. Starting with the water, so it stops being a problem because of shortage (droughts) or because of excesses (floods). Instead, it transforms into the vital element that gives the possibility for vegetation to grow into the urban framework, generating shadows and oxygen. This recreation of the native landscape and its vital cycles, is the conductive string, proposed in order to give value to the urban and natural pieces of the city, and also link them with one another creating a continuous walkable public space. The proposal is not based on architectural solutions or design gestures, it is aiming to give value to the natural processes, those things that transcend, the essential for the next hundred years of Seoul.
