Situated on approximately one acre in the prestigious hills of Cowan Heights, this exceptional North Tustin estate has been completely reimagined through an extensive, top-to-bottom renovation by licensed contractors. Thoughtfully designed by a professional interior designer, every detail was carefully selected to create a home that is both stunning and functional. From the custom finishes and luxury materials to the significant structural and mechanical upgrades, this is far more than a cosmetic remodel; it's a rare opportunity to own a truly turnkey estate where modern luxury, privacy, and resort-style living come together in one of Orange County's most sought-after neighborhoods. Offering 4,866 square feet, the home features 5 bedrooms and 4.5 bathrooms with beautifully designed living spaces, engineered wood flooring, custom cabinetry, quartzite surfaces, handcrafted tile-work, and a chef's kitchen equipped with premium Viking and Fisher & Paykel appliances. Beyond the exceptional finishes, the home has undergone a comprehensive renovation with significant structural, mechanical, and energy-efficiency upgrades, including all-new windows and glass, upgraded insulation, two new 5-ton HVAC systems, two tankless water heaters, and new WiFi-enabled garage doors. Designed for exceptional indoor-outdoor living, the resort-style grounds feature a fully renovated pool, pool house with sauna, rebuilt tennis and pickleball court, new hardscape, professional landscaping, and a new irrigation system. The property also offers outstanding potential for a detached ADU, guest house, multigenerational living, home office, or income-producing rental with the possibility of a separate private entrance. Known as one of Orange County's hidden gems, North Tustin offers estate-sized properties, mature tree-lined streets, and a unique sense of privacy while remaining close to shopping, dining, and major freeways. The home is also located within the highly regarded attendance areas of Arroyo Elementary and Foothill High School. A rare opportunity to own a truly turnkey estate where designer vision, quality craftsmanship, and extensive upgrades come together to create a private resort-like retreat in the heart of North Tustin.
