As Hong Kong is situated on the waterfront, climate change and resultant sea level rise will seriously affect the city, contributing to greater land shortages and storm events. While land reclamation is the normative response to land shortage, this project proposes to rethink the perception of living on the sea, through an investigation of domestic space, live-work arrangements, and construction technology.This project depicts a future settlement scenario in 2047, before which a new aquatic squatter settlement forms near Lantau Island. The designer explores a boat builder’s house as a deep exploration of spatial qualities, mixed use spatial programming, and construction technology as a sophisticated evolution of the boat construction vernacular. The resultant research explores construction supply chains, relationships between technology and ergonomics, and improved construction techniques.
