Rooted in the past, anchored in the future, and embraced by the rare feeling of being worlds away, this extraordinary architectural estate evokes a profound sense of permanence and belonging. Set on 4.76 private acres in the Knights Valley AVA, occupying the original homestead site of Captain Franz, the 19th-century settler for whom Franz Valley is named, the 2019 residence blends striking design, timeless materials, exceptional craftsmanship, and thoughtfully engineered systems. Designed for seamless indoor-outdoor living, walls of glass open to resort-inspired grounds where pool, spa, fire, and gathering spaces unfold naturally across the landscape. Motorized pergolas, a fully equipped outdoor kitchen, and multiple fireplaces create a setting equally suited for quiet evenings and special occasions. Inside, walls of glass, concrete floors and walls, exposed steel, and estate-sourced wood create an environment of warmth and understated luxury distinguished by a rare level of craftsmanship. A dramatic great room serves as the heart of the home. The kitchen reflects the same commitment to craftsmanship, where custom walnut cabinetry milled from the estate itself, zinc cabinetry and countertops, and a premium Thermador appliance suite create a composition as functional as it is beautiful. Wrapped in glass and opening directly to the pool and outdoor living spaces, the main-level primary suite enjoys sweeping views and is complemented by a luxurious spa-like bath. Upstairs, two generously sized guest suites, each with its own bath, are thoughtfully separated by a family room, creating a private and inviting wing that balances connection and privacy. Surrounding the residence, a rare two-acre estate Malbec vineyard rooted in the volcanic soils of the Knights Valley AVA brings authenticity and romance to everyday living. While only 12 minutes from Calistoga, the estate, framed by vineyards, orchards, olive trees, and rolling hills, celebrates the beauty, rhythm, and traditions of Wine Country, completing a property defined by permanence, belonging, and the rare feeling of being worlds away.
