The auditorium of Broadcasting High School was a mixture of warehouses, classroom spaces, filming spaces, and club activities in one space. The space was newly divided according to the program and purpose of the auditorium. The space was divided into a photo zone studio and a warehouse. Horizon Studios has a large three-dimensional screen that can take pictures on three sides, and a lighting device exclusively for shooting is installed at the top.

The front space of the studio is a multi-purpose classroom space for acting classes and dance classes, and a long bench for classes and filming as the ceiling structure of the Horizon Studio descends down the wall. In addition, a dark gray track is created along the periphery on the floor, and the track on the floor is benched again, and the flat element turns into a three-dimensional element. The curve of the track, the curve from the bench to the ceiling, and the curve of Horizon Studios give a soft sense of unity overall. Although the Horizon Studio and the classroom space seem to be separated, you can feel that they lead to one.

Each of the warehouses was equipped with a door to reduce the movement. With this completely separated space, the auditorium can be used more efficiently and conveniently. The space used can be reached through a lamp to the auditorium with a large stage. It can be used as a warehouse, but it can also be used as a stage preparation space. A large angle cabinet was placed inside the warehouse to store existing musical instruments and filming equipment.
