This nonprofit project, undertaken by students and guided by professionals of The University of Hong Kong, leveraged the challenge of heavy rainfall transforming it into a crucial resource to alleviate the community's freshwater scarcity. Taking into consideration the site's environmental and cultural context, the building adopts a cascading form, culminating in a series of tiered roofs. These roofs channel rainwater into a collection lotus pond, and subsequently into an underground recycling system, from where clean water is eventually pumped up into the building for use.
