At first, there was only scenery without boundary and view to the ground. The floating circular trail separate the internal from the external landscape, but there was no substantial separation. Being soft and undulating, it extendes the landscape to the air - an inseparable structure growing from the ground. The white GRC curtain wall drops from the air to ground, making the whole structure like clouds floating above the ground. Finally, we get a smooth structure with free curves, which seems to be unintentional freedom and integration, but in fact, all deliberate improvisations.
