We have a special place in our green hearts for sustainably built schools, and the striking International School of Sacred Heart in Tokyo is no exception. While the rest of the school was being constructed, it was necessary to create a short-term but still inspiring place on a small patch of the school's field for first and second graders to learn. Atelier SNS responded to this design constraint by incorporating both passive and Japanese design strategies into a circular building that is super energy efficient. Best of all, the whole thing can be dismantled and re-used.
