Welcome to Hacienda de las Palmas… Behind double gates with access from both Alameda Diablo and La Cadena, this exceptional Spanish-style Hacienda blends timeless character with modern sophistication. Originally built in 1949 and thoughtfully renovated, the estate honors its rich architectural heritage while offering every comfort for today's lifestyle. Set on 1.53 gated acres spanning two parcels, the property encompasses approximately 6,992 square feet across the main residence, an impressive poolside casita, and finished barn. A rare opportunity awaits on the included .77-acre unimproved homesite, offering endless building possibilities or equestrian use. Inside, an original vaulted wood-beam living room ceiling, handcrafted details, and sun-filled living spaces create a warm and inviting atmosphere. The predominantly single-level floor plan features six bedrooms, six bathrooms, and two half baths. Designed for both everyday living and gracious entertaining, the chef’s kitchen is appointed with premium appliances, quartz countertops, and a spacious butler’s pantry. A dedicated wine room, beautifully updated bathrooms, and thoughtfully curated finishes throughout reflect the home's commitment to quality and authenticity. The luxurious primary suite with adjoining coffee nook serves as a private sanctuary. The home's only second-floor space is a secluded office retreat, including a full bathroom, and balcony overlooking the estate grounds and surrounding hills. Step outside and the grounds become the showpiece. Towering palm trees, Spanish ceramic tiled patios, and a level, expansive lawn create a magical backdrop, framed by mature privacy hedging and lush plantings throughout. A sparkling rectangular pool built in 2021 anchors the outdoor entertaining areas, complemented by a sprawling 1585 sf poolside casita with family room, changing/exercise room, two bathrooms, and bedroom. A remodeled entertaining barn and a golf cart garage add even more flexibility for hosting and hobbies, while the rolling hills beyond provide a constant, picturesque backdrop. Perfectly positioned along prestigious Alameda Diablo, and a short stroll to Diablo Country Club, this extraordinary estate offers a rare combination of history, privacy, flexibility, and luxury in one of the East Bay’s most coveted settings.
