The large space was divided into four areas by the fire proof area and the public corridor, interfering with the unity and communication. Thus, the fire shutter was replaced with glass doors, and all the entries to each area were unified as much as possible to enhance the sense of openness.

There is a multi-purpose lounge at the main entrance, which is used as a common room, cafeteria, restaurant, event space, and a meeting place with outsiders. Being on the opposite of the area for the company executives, it encourages communication between the top management and the employees. The two facing walls of the grand conference room are finished with glass partitions, and the materials of rich texture such as lumber, cement block, steel sheet, metal, and marble are used in places to deliver the atmosphere of a construction site in a discreet manner.

On the inside, the work space is separated by the departments, and among them is the "Between Zone" for meetings, relaxation, Reading books and O.A devices.
