The ground plan is a cruciform. On the one hand, due to its division it establishes connections to the small houses in the neighbourhood, while on the other hand, the division originates from the space required as well as the need for separate playareas in the open. All the external walls of the classrooms are multi-functional. The blackboards are forming the doors of the cupboards for teaching materials. The glazed external doors are framed on either side by chests containing toys, serving as seats at the same time.
