We needed an architectural idea to contain all the programs of the school in the limited area. In order to preserve the main dedicated spaces, we aggressively used the outdoor space as passages instead of indoor hallways. The building surrounds the site, and each classroom is open and connected to the courtyard in the middle. Like the spatial structure of Seowon in the Joseon Dynasty, the classrooms face each other with the courtyard in the middle. At the front of the site, we placed the auditorium and cafeteria, where there is the best view. Between the inside and out, there is a toenmaru, which is a traditional Korean narrow wooden porch that runs along the outside of the room. The 2nd-floor outdoor hallway is also a roof for the 1st floor and makes the courtyard more active in the center of the building. We were concerned it would be inconvenient to the users for all the spaces were directly connected outside. However, the school's education philosophy emphasized the relationship with nature, so we were able to come to an agreement with the school members.
