Seller is open to private financing for qualified buyers. Introducing Sweeney Canyon Riverside Estate, a once-in-a-generation opportunity to design and complete an iconic wine country family retreat and or B&B in the heart of the coveted Sta. Rita Hills AVA. Set across 49 breathtaking acres with approximately 1,400 feet of Santa Ynez River frontage, this extraordinary Mediterranean-inspired estate sits among rolling vineyards, oak-studded hillsides, and endless valley vistas, offering the kind of privacy, scale, and natural beauty rarely found on California's Central Coast. Originally envisioned as a grand family legacy compound, the unfinished residence was constructed in 2012 with robust steel and I-beam framing. Today, the thoughtfully designed floorpan with living space of approximately 7,476 square feet floor plan (with possible further expansion), includes seven bedrooms, six full bathrooms, three half baths, and an impressive 5,000 square foot daylight basement with roll-up doors ideal for a collector car gallery, wine cellar, wellness retreat, tasting lounge, creative studio, or luxury entertaining space. The total structure spans approximately 14,423 square feet across four levels, all designed around an elevator shaft for seamless access throughout the home. Framed, plumbed, and ducted, with an active building permit already in place, the estate is poised for its next chapter and ready for a visionary buyer to bring the final masterpiece to life. Imagine arriving through the canyon to a dramatic two-story foyer, sun-drenched entertaining terraces overlooking the river valley, and expansive indoor-outdoor living spaces designed for unforgettable gatherings under wine country sunsets. Beyond the residence, the land itself offers exceptional opportunity. Approximately 35 usable acres, two wells, a shared 30,000-gallon cistern, and the property's history as the Robert Parker acclaimed Chardonnay, Sweeney Canyon Vineyard creates the perfect canvas for a private estate vineyard, equestrian ranch, luxury retreat, boutique hospitality concept, wellness destination, or multigenerational compound. With the flexibility offered under the Santa Barbara County Agricultural Enterprise Ordinance (Jan 2025), the possibilities here extend far beyond a traditional residence. Surrounded by one of the most celebrated Pinot Noir and Chardonnay growing regions in the world, where acclaimed vineyards routinely produce 94+ point wines, Sweeney Canyon Riverside Estate offers more than just real estate. It offers the chance to create something deeply personal, enduring, and truly unforgettable. Be sure to watch the cinematic video tour to fully experience the scale, setting, and incredible vision this landmark property has to offer.
