Elementary School Melle

The city of Melle wishes to build a new primary school on a completely open, unidentified plot of land.
Our main goal was to endow this empty lot and its surrounding neighbourhood with a sense of community, whilst staying sensible about the amount of open space we occupy. How can this new school, with its own community during the day and its open doors after-hours, the existing sports hall and the surrounding public park function as one communal organism in a safe and playful way?
