Courtyard Continuum is a climate-adaptive communal housing prototype that reimagines collective living through an integrated courtyard ecosystem. Designed for high-density urban contexts, the project combines modular construction with passive environmental strategies, rooftop water harvesting, and seasonal reuse systems to reduce resource demand while enhancing social connectivity. A continuous spatial loop links housing, landscape, and shared amenities, creating a resilient living environment that supports community interaction, environmental performance, and long-term urban sustainability.
