The site of school is located in Hanoi, which is asymmetric and surrounded by lots of tower blocks. The school comprises a kindergarten, primary, and secondary school. It not only has separated playgrounds divided by ages but also a common playground, which could be used by everyone. To fit in the asymmetric site and create playgrounds separately, the school is designed with a zigzag form through the site. Series of continuous spaces which like a loop combined with a flexible bridge corridor system creating serial changes and unexpected views for the users. By this design, classrooms are oriented to the North and South and maximize collecting of natural light and ventilation. The sports field, gymnasium and canteen are placed at the end of wind direction, as a result noises are effectively reduced.
