Criss-Cross City is a modular and expandable lumber armature that extends across Hong Kong. Located in the Pearl River Delta, Hong Kong is the world’s largest megalopolis, home to over 120 Million people, and an area expected to nearly double in density by 2050. Tapping into the region’s massive eucalyptus and bamboo plantations, the project hypothesizes a flexible yet robust platform to imagine a new urban form of living. This multi-scalar approach re-thinks the relationships between forestry and urban life by drawing on global and regional lumber practices to produce urban interventions. The infrastructural scaffold operates within and above the existing city using a hexagonal organizational logic that connects towers to bridges to platforms, providing new relationships between city and ground.
