This article describes the design of a flexible school for childhood education in Milan, Italy. The architecture of this school takes into account children's development and the different ways they experience space according to their age. The facilities will include not only a nursery school and kindergarten, but also a drop-in day-care centre, a play centre and outdoor areas to develop the senses. This school building will respond to the need for a facility that can later be expanded to become the key educational site for the neighbourhood, a place for gathering and interacting outside of school hours, not only for children but also for adults. Attention focuses on developing a unified and coherent educational project that targets newborns to six-year-olds, and architecture that can be expanded to the elementary and secondary levels through a system of "flexible and growing buildings" while meeting the various needs of different age groups.
