A Rare Hilltop Jewel in Tustin Ranch Estates,Perched atop a private knoll in the ultra-exclusive, 24-hour guard-gated enclave of Tustin Ranch Estates, this iconic mansion is a hidden sanctuary where timeless elegance meets modern grandeur. Set on a 34,400 sq ft lot with over 9,273 sq ft of living space, the estate features 5 spacious bedrooms, 8 bathrooms, and a 4-car garage with an extended motor court for 10+ additional vehicles. Meticulously crafted with premium upgrades, the chef’s kitchen is a culinary dream—equipped with custom German Miele appliances, separate Chinese and Western cooking areas, and tailored soft-close cabinetry with layered pull-out drawers. Four ovens, two oversized refrigerators, multiple cooktops, and three dishwashers offer power and elegance for everyday living and grand entertaining. The main level welcomes you with a refined in-law suite, formal home office, bright great room, and a flexible entertainment lounge that easily converts to a private theater. Resort-style features include an indoor resistance pool, sauna, and sunlit solarium with fireplace. Dual formal dining rooms and a wet bar elevate hosting possibilities. The fully integrated smart home system offers surround sound and Wi-Fi amplification indoors and out. Upstairs, the grand primary suite enjoys a private view balcony with sweeping mountain and city-light views. Three additional en-suites and a large secondary study provide flexible living for multi-generational needs or remote work. Three access points—a grand spiral staircase, secondary stairs, and a private elevator—ensure seamless flow throughout. The landscaped grounds bloom year-round with mature trees, creating a tranquil garden oasis. With no rear neighbors, enjoy panoramic park-facing views and resort amenities: a saltwater pool with spa, basketball court, mini golf, and built-in BBQ. Expansive courtyards offer space for unforgettable gatherings under the California sun. Freshly repainted and updated with new premium carpet, this home is move-in ready. Ideally located near top-rated elementary and middle schools and just minutes from acclaimed Beckman High, this is a rare opportunity to own a true legacy estate in the heart of Tustin Ranch. Welcome to the pinnacle of Southern California living.
