HR classrooms and teachers' rooms for primary and middle school students are located in the north units, and HR classrooms for high school students are located in the south units. Commonly used facilities such as the media center, laboratories, presentation room, halls, open atrium, and cafeteria have been placed near the center of the building, with each floor containing classroom units connected to these facilities to create a sense of academic unity throughout the school.
