The ceiling material of the elevator's front hall at the entrance is the wavy metal plate with hand-knock surface.

The 3.2-meter high facade of the main door of private dining room is clad in rich layers of sculpted metal strips, fluted woods and inlaid marbles, which contain details in a simple manner.
