  • SUPER INSULATED CONSTRUCTION

    The home’s exterior incorporates utilitarian materials of rough-sawn, pine tar stained siding, Corten steel shake tiles and standing seam metal panels, and raw board formed concrete to provide richly patterned surfaces that will transform over time as the materials patina with age. The interior plays off the same wood, steel and concrete detailing and pays homage to the neighborhood’s grand white oak trees in the flooring, ceiling soffits and kitchen cabinets.  The home’s composition, however, is more than skin deep. Beneath the façade, lies a high-performance envelope and mechanical systems utilizing Passive House detailing.
