What we choose to build with dramatically shapes how we perceive space, and weathering steel allows us to understand architecture through a temporal lens. Drawing together 12 corten houses, each of the following projects explores the steel alloy’s application through interiors and exteriors alike. Made to change over time, these residences show how architects can embrace natural forces and the imprints they leave behind. The Sagaponack House was designed with a densely packed program between the ocean and a pond. Embracing the surrounding site features, the building volume and fenestration was formed to engage views with stepped planters, a plinth and steel moment frame. Heavy gauge corten steel and cedar siding was used as cladding.
