All the school buildings are built on the central corridor principle, where concentration classrooms and special classrooms (e.g., science, arts) are grouped in rows on both sides of the corridor. Room programs are almost identical, including classroom design and special subject rooms and their sizes. All the concentration rooms in the schools or colleges have libraries and dining and kitchen areas. Although the basic principle of the floor plans of the school buildings (classrooms on both sides of a central corridor) and the room program are almost identical in all cases, the architecture of buildings is very varied and diverse, even rich. The concentration room plan buildings are placed on the site to consider the context of the location and neighborhood conditions.
