Located in Vancouver, Canada, this residential project by Arno Matis Architecture features façade openings that are programmed to provide passive shading, and act like an Aperture: opening and closing in response to the unique solar exposure of each façade. Apertures are deeper on the south elevation to provide increased sun shading, and more shallow and open to the North, to allow for additional light. Each aperture is framed with natural wood-in-glass; a building skin that is the first of its kind. A mahogany veneer encapsulated between two glass layers, the system allows the wood to be preserved in its natural form without staining or color treatment; the richness of the natural wood grain is enhanced through refracted light.
