Hidden behind private gates and enveloped by lush, mature landscaping, The Villa at Alto Mar is an extraordinary coastal Southern California estate where refined architecture, exceptional design, and resort-inspired living converge. A winding drive guides you towards a secluded sanctuary designed for grand-scale entertaining, multigenerational living, and effortless everyday luxury. At the heart of the estate stands an approximately 8,000-square-foot, four-bedroom, seven-bathroom residence, thoughtfully reimagined in a $4 million renovation in 2021, with interiors by designer Hayden Crosby, granddaughter of Bing Crosby. Soaring ceilings, exposed beams, white oak floors, solid wood doors, and warm natural textures establish an atmosphere of understated sophistication. Exquisite finishes include Macchia Vecchia marble countertops, custom white oak cabinetry, a Viking range, Sub-Zero refrigeration, and cream-toned heated concrete floors. The luxurious primary suite features an expansive custom oak dressing room and spa-inspired bath with a steam shower, dramatic marble accent wall, custom brass-framed mirrors, and solid brass and glass detailing. Designed around a magnificent central courtyard anchored by a mature tree and statement fireplace, the residence embraces seamless indoor-outdoor living. A resort-style pool, outdoor kitchen and barbecue areas, fire pits, expansive lawns, and intimate gathering spaces create an exceptional setting for entertaining. Inside, a private office, theater, game room, children's playroom, and beautifully appointed wine room complete the experience. Three additional residences, offering a combined six bedrooms and four bathrooms, provide exceptional accommodations for extended family, guests, or estate staff, establishing a true private compound. Beyond the main residence, a whimsical open-air entertaining pavilion, expansive sports field, basketball court, imaginative children's play areas, and generous event and recreation lawns further distinguish the property. Ample parking accommodates approximately 15–20 vehicles. Expansive open acreage presents additional possibilities for gardens, a vineyard, recreational amenities, or future equestrian uses, subject to applicable approvals. A private gated connection leads to The Ranch at Alto Mar, a separately offered sister estate featuring a Montana-inspired residence and established equestrian facilities. Available independently or together, the properties offer the rare opportunity to create an extraordinary Southern California legacy compound. Grand yet intimate, sophisticated yet effortlessly inviting, The Villa at Alto Mar is more than a residence. It is a private world unto itself, thoughtfully created for generations of living, gathering, and unforgettable experiences.
