The school was created from two symmetrically identical functional areas on an almost square floor area. The two side wings of the building accommodate the classrooms, the central parts of the building with gable roofs served as gyms.
The blocks for the classrooms have windows facing east and west to avoid strong midday sun in summer. The classrooms are separated from the hallways with thin partition walls. The top of the partitions are fitted with glass panes and tilting windows to allow natural light to illuminate the hallways. The lower part of the partitions is used for the students' lockers. In front of the specialist cabinets are instead of lockers placed showcases for exhibits. Each floor is designed in a different colour for a better orientation. Originally there were drinking water fountains on all floors, which are architecturally preserved without any function.
The two gyms in the middle can be connected by opening sliding doors to create a large ceremony hall. Today one of the gym areas is used as the school's cafeteria. The flat roof areas of the connecting buildings were originally planned as roof terraces, which were to be used for outdoor classes and gymnastics exercises.
