This project was the expansion of the use of the existing facilities of this Belgian international school. A new gymnasium was constructed with large spans using laminated wood. Making use of the high ceiling of the existing gymnasium, to undertake conversion, a floor was installed in the middle, a cafeteria was built in the lower space and classrooms were built into the upper space. The brick and plaster exterior finishing materials, and the curved roof of the existing building were also used for the new building, in order to maintain the dignified atmosphere of the school, and to unify the design of the overall school campus.
