Sitting on wetlands and settlement, and lying at the heart of the Northern Metropolis, scheme, San Tin is at the cusp of ecological responsibility and development pressure. With the area’s fishponds and village fabric and the social-infrastructural programs often overlooked, the studio asks how architecture can stage a credible public food economy—from fish farming to fish markets and cooked-food culture—while respecting flood regimes, non-intrusive pond edges, and biodiversity. With the goal to seed social infrastructure and a cultural economy for the area, for the community and to attract visitors, students will engage a complex field of conditions and design precise architectural interventions that choreograph a full cycle: catch/receive/farm → grade/hold → process → cook →plate → dine → clean-down → treat waste → return to landscape. And explore how architecture can turn the system into a performative, legible cycle—improving hygiene transparency, deepening ecological literacy, and cultivating everyday participation.
