Axis Mundi, XYZ House, 2020

Where would you build your dream hideout? This design by the American architecture studio Axis Mundi imagines a cruciform-like structure, clad in corten steel, jutting out over the Swiss Alps. Titled XYZ House—a reference to its mutually perpendicular planes, which mirror the three Cartesian coordinates of X, Y and Z—the bold structure, and its majestic setting, are intended to evoke the Romanticism of Caspar David Friedrich and Heinrich Heine. “The project is a ruin from the future,” the firm’s website explains. “Its poetic power lies in its supreme muteness, as a place to contemplate the horizon and eternity in silence.”
