An original and modern architectural design concept that has traces of the sharp-edged form of the building has been accepted as the focus of the design. The specially designed acoustic fabric covered panels on the ceiling strengthened the design aesthetically as well as functionality with the use of corporate color. Open office spaces are thought to be convertible and articulating spaces that include different uses as well as pure functions. With the addition of social areas such as meeting, relaxation room and kitchenette within the office spaces, which were created to include a dynamic and social fiction, they have been turned into special spaces for employees to use.
