Architecture as Landscape reconceptualises architecture not as object-making but as landscape practice: an active agent within ecological, cultural, and territorial systems. Centered on San Tin’s contested terrain, the studio challenges the binary between nature and development by treating architecture as a spatial and temporal mediator. Through psychogeographic mapping, sectional drawing, and material-based modeling, students investigate liminal conditions where human and non-human systems intersect. Referencing the symbiotic practices behind Gei Wai ponds and Satoyama landscapes, the studio foregrounds architecture’s capacity to shape and be shaped by environmental processes. The site is understood not as a fixed boundary but as an emergent field of relations; hydrological, social, and economic. Architecture becomes a constructed ecology embedded in cycles of resilience, adaptation, and coexistence. This approach fosters speculative yet grounded interventions that dissolve disciplinary boundaries and propose inclusive, multi-scalar futures rooted in landscape thinking.
