missing link by han wook kim from korea

Today, most of cities are covered with the asphalt and concrete blocks. However, the land covering impedes the ecological cycle. Moreover, it causes urban desertification, heat island effect, and a flood of sewage. But above all, the communication between oppidan and nature was cut off by the land covering. So I propose the smallest urban park instead of a huge green area project. This project is to redefine the relationship among the interface between urban&urban, urban&nature, oppidan&nature through the ecological cycle. In the meantime, a bus stop has had the only meanings of dry transferring and boring waiting. But the bus stop in a city is not only a meeting place of different elements, but also a public space where citizens are the most easily accessible. So I propose to make the bus stop do a role of the smallest urban park.The new bus stop will have a volume to be recognized as a hill by what people and nature circulate, not as just a station where has flowerpots. Through this volume, oppidan will find a new interface between city and nature in urban elements, and get back a missing link of the volume they could go up and sit down.
This smallest urban park has a role of water pocket. This place makes rainwater pure by ecological cycle, not by a chemical process. One bus stop can store 12,500ℓ to maximum once through Aquifer. If 10% of bus stops in Seoul(3000 pcs) are replaced with the new one, water will be secured for 11,000,000 people to maximum(per 340ℓ). In addition, this water pocket system will prevent a flood of sewage by storing some amount of water flowing to the sewage. The water pocket system supplies water not to cut off a flowing of people and nature in frequent droughts and floods.The surface of the bus stop is covered with 33.8㎡ green area. If 10% of bus stops in Seoul(3000 pcs) are replaced with the new one, we will have 101,400㎡ green area. This covers equal 1/3 area of the Central Park in New York. The wide green area can prevent urban desertification and heat island effect from doing transpiration.
