House on Lac Grenier is a minimalist residence located in Quebec, Canada, designed by Paul Bernier Architecte. The form is clad in a single material, with vertical cedar slats of varying width and thickness placed in an open-work manner. The building’s weatherproofing is assured beneath the spaced slats, which conceal the flashing, drip edges, and trim usually visible on the exterior of traditional wood structures. The surface reads instead like a palisade that follows the shape of the building and into which openings have been cut.
