The residential building located adjacent to the road was called Imperial Envoy Avenue where the US Ambassador's residence and American Embassy were located. The rhythm of the public facilities space design is based on the idea of water. As the metaphor of time and traffic creates the imagery of transparency and reflection of flow movement. Wood grill ceiling with curved wavy three-dimensional shapes the water flow from the main entrance all the way to the reception desk and continuing through the lounge and mailroom, the ceiling of the underground parking area as well.
