Located in front of a large park, the space of stairs which faces the forests projects images of people who go up and down the stairs, providing vital public space to the city. Climbing up and down the stairs is like walking above the park, the space is like a “Floating Promenades”. It is “Void of the Light” where one feels nature including light, wind, rain, and clouds. At night, the stairs float and illuminate the city, thus, “Void of the Light” is transformed into “Tower of the Light”. Simple silhouette demonstrates new public spaces, symbolizing new symbiosis between buildings and city.
