Homefarm is a conceptual proposal for the next generation of urban retirement housing. It presents a living and farming typology for Singapore (or elsewhere) that combines apartments and facilities for seniors with vertical urban farming. Seniors live in a high-density garden environment created by a vegetable farm, where they may find employment. SPARK’s aim is to generate discussion about the many potentials that can emerge from the mixing of two typically separate realms. The research-based design addresses two pressing challenges faced by Singapore: how the city state might support a rapidly ageing society, and how it might enhance its food security (90% of which is currently imported).
