Tutor's Notes // Bob Shi’s thesis offers an affective and culturally grounded methodology for understanding and intervening within a wild patch of secondary forest nested within Singapore’s dense urban city. Their intervention prioritises emotional, cultural, and ecological entanglements over managerial control. Grounded  in  rigorous  fieldork  and  embodied  knowledge  of  Alexandra  Woodland,  the  project highlights the Malay archipelago’s folkloristic spirit or semangat, emblematic particularly in the figue of the hantu (ghost). Bob’s interest in the forest emanates from their transient pockets, guarded by the more-than-human, and momentarily free from capitalistic regulation and order. They deftly articulate the wild remains only by a politics of stealth, and through a strategy of the non-useful. In this vein, the thesis adopts the hantu as its critical lens. Engaging with the hantu and its proverbial wild habitat, Garbage Trees and Hantus maps a guide and a series of interventions that are double-edged, cultivating care and reverence for this precarious site, while at the same time recognizing the necessity of transience and flux.Negotiating rigid conservation strategies, the design strategy embraces the forest’s rich atmospheres and ephemeral qualities through an unlikely non-native tree species. The self-seeding Albizia tree thrives in Singapore’s rough and rapidly transforming urban landscape, sprouting freely in overgrown sites which once housed buildings or littered with construction debris. Popularly known as a “garbage tree’ with a transient lifecycle, the Albizia is reframed as a co-architect of haunted, and culturally embedded, civic-natural space. By recognising informal, multispecies interactions—among hikers, foragers, birds, and ghosts—Garbage Trees and Hantus proposes a new spatial language. It imagines architecture not as enclosure or system, but as the transient outcomes of sensitive engagements with ecological and spiritual rhythms.
