CITY SCHOOL
DUFFERIN HIGHSCHOOL
Partner: Zhi Hui Chiang
The city high school comprises two types of programs: artistic and technical, divided into separate buildings. The aim is to celebrate the different programs by connecting them together. By separating the buildings and lifting the bridge off the ground, the space underneath the bridge is intended to encourage interaction. The spaces in the middle are where the diversity of the students at the school is brought together. The garden aims to foster communal interactions and build a strong relationship with the other programs to support
student life.
The idea of bridging was depicted on the building by creating a further separation between the joining of the building blocks to create a miniature bridge condition on the floors. The design focuses on the gap condition that is created between the ‘glass block’ building and the brick block building. While the glass block is covered by a mesh façade, the front facing brick building is formally different and is proud of the material. This allowed for the addition of a visual separation through the use of clear class curtain wall on the gap condition.
