Origami House: A Tectonic Response to Solar Geometry
The primary challenge of the Origami House lay in its L-shaped topography and demanding solar orientation. Faced with direct incidence on the primary facades, the design necessitated a robust system of horizontal and vertical solar filters. Rather than utilizing redundant components, the project adopts a "folded" structural language inspired by Japanese origami. This rhythmic concrete skin achieves a dual purpose: it significantly reduces 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 cross-ventilation to ensure passive cooling.
The project’s centerpiece—the cast-in-place exposed concrete origami—stands as a testament to technical precision. Executed by Pelissari Engenharia and master builder Leo, the timber formwork was assembled with artisanal rigor, treated less like a construction element and more like a large-scale sculpture. This house serves as a tribute to the collective effort of the job site; a realization that high-quality architecture is inherently the result of a synchronized, multidisciplinary craft.
