Court: After office on the 2nd floor was placed on top of the fold concrete slab, In order to connect the ground plane with office space on the 2nd floor, the office is divided at the center to have a courtyard. The ground plane that shifted up can directly touch with the 2nd floor office. Office users can go outside to enjoy the outdoor space and can have view of the court yard. For typical building, office space on the second floor never has direct relationship to ground floor. The new building for Pttep will change this perception.
