By framing greenhouses as ‘healer typologies’, “Buoyant Overhaul” integrates greenhouse structures and technologies to improve the urban rehabilitation of old buildings. The thesis seeks chances where greenhouse technologies can be plugged into ‘unliveable’ structures, allowing extensions of their functions to rehabilitate liveable settings. Working along Victoria Harbor, the structure makes use of the benefit of water access to old, its rehab procedures redefine technology-driven social ties and provide greening incentives while plugging into host structures for durations of 1 – 2 months.
