Sited above the Malibu coastline, a magnificent Santa Barbara Spanish-inspired estate has redefined the meaning of sustainable luxury. This 21-acre sanctuary, completed in 2021, masterfully melds Santa Barbara architectural elegance with cutting-edge sustainability, offering a rare opportunity for those seeking both opulence and environmental consciousness. The approach to the property sets the tone for what lies ahead: a private driveway winds through a working vineyard, leading to a meticulously crafted residence. The home's grand entrance opens to reveal a tranquil inner courtyard, where a fountain provides accompaniment to outdoor gatherings around the fireplace. This seamless blend of indoor and outdoor living spaces—a hallmark of Spanish Colonial Revival architecture—continues throughout the property, anchored by a new resort-style pool. Inside, white oak floors flow through open-concept living spaces, while French doors frame spectacular 360-degree views of the coastline, Catalina, additional Channel Islands, and mountains. The chef's kitchen strikes a balance between form and function, featuring marble countertops, a commanding center island, and professional-grade appliances. A wraparound entertainment terrace captures both dawn and dusk, making it an ideal setting for year-round entertaining. The primary suite offers a private retreat, complete with a covered terrace and loft media room. Its spa-inspired bathroom, with its freestanding soaking tub, provides a luxurious escape with panoramic views. Three additional en-suite bedrooms, an office, and a fitness room round out the living spaces. What truly sets this estate apart is its commitment to sustainability. As one of the region's few fully off-grid luxury properties, it operates on a sophisticated system of on-site water, solar power, and Tesla Powerwall technology. Built with non-combustible materials, the home represents the pinnacle of efficient, sustainable design without compromising on luxury. The agricultural potential adds another dimension to its appeal. With rare approved plans for expansion and two additional building sites already prepared, it offers unique opportunities for agricultural development in an area where such permissions are increasingly scarce. Located adjacent to the Backbone Trail and minutes from Malibu's beaches, it stands as a testament to how luxury real estate can embrace sustainability while maintaining the highest standards of comfort and sophistication.
