Small courtyards with lawns are inserted into the site to create sound barriers, bring natural light inside, help cross ventilation, and increase the water catchment area. Doors can slide open to join 2 or 3 spaces together, allowing the school to hold the students performances, graduation ceremonies, etc, to accommodate a large group of people. A wooden deck that covers the sandbox can be lifted to create a temporary stage for performances. Previously, the school had to rent spaces in other buildings for performances and graduation ceremonies, and transport the children to nearby parks for them to be able to enjoy the trees and fresh air. Now the children can run and play on the grass. A group of small fruit trees are planted in pots on the roof, an element to educate the city children who mostly have seen the fruits, but never the trees.
