Origami House: A Tectonic Response to Solar Movement. The primary challenge of the project lay in its unique L-shaped topography and demanding solar orientation. Faced with direct incidence on the primary facades, the design necessitated a robust system of integrated horizontal and vertical solar filters. Rather than utilizing redundant components, the project adopts a sophisticated "folded" structural language inspired by Japanese origami. This rhythmic concrete skin achieves a dual purpose: it significantly reduces raw material consumption while optimizing thermal inertia and shading. The environmental performance is further enhanced by a double-height social volume that promotes the stack effect, working in tandem with natural cross-ventilation to ensure constant, efficient passive cooling throughout the year.
