Tucked into a Vail hillside, this modern spec duplex was born from a thoughtful balance of opportunity and preservation. The client, who owns the neighboring home, sought to develop the site in a way that protected their views while creating two market-ready residences. Side A spans 5,400 square feet and Side B 4,300, each with at least four bedrooms. Flat roofs, clean lines, and stepped massing follow the natural grade, allowing both privacy and framed vistas. Expansive decks and operable doors connect the interiors to the alpine air, while materials like cedar siding, modern stone, and black metal lend a timeless, contemporary edge.
