The classrooms receive natural light from two sides, from the large windows on the east facing façades and from the strip of windows located at the highest point on the inner wall of the classroom. This means that the buildings' saddle roofs are offset in regard to one another, and a vertical strip of windows is inserted into the opening between the two roof planes. This provides the classrooms with nice natural lighting. At the same time it provides the classroom wings with an interesting exterior modulation. The youngest children stay in the wing that is painted red.
