1875 La Cuesta Welcome to the crown jewel of Lemon Heights, a gated Mediterranean Revival compound perched above North Tustin’s most coveted ridge. Built in the 1930s, this residence is steeped in history yet utterly timeless. More than 90 majestic trees, many exceeding 50 feet in height, envelop the two landscaped parcels (totaling 2.4 acres), creating a tranquil, private oasis that stands apart from the world. The views are breathtaking and sweeping from Catalina to Palos Verdes, then turning to reveal rolling hills and snow-capped peaks. And unlike most ridgeline estates that trade flat land for elevation, this property defies convention, offering lush, expansive lawns paired with cinematic vistas. For nearly 30 years, a single family has stewarded this 6, 500-square-foot residence, and that care shows in every detail. Soaring ceilings, hand-applied stucco walls, antique walnut woodwork, and carved stone mantels evoke old-world elegance with modern refinement. This estate is a compound unto itself, encompassing a guest house, carriage house, multiple garages, a recreation center, and an outdoor veranda exceeding 1, 000 square feet, perfectly suited for grand entertaining or quiet sunsets. A circular motor court, central fountain, and garden pathways invite discovery. At the rear, an infinity-edge pool and spa command dramatic views by day and glittering city lights by night. Just when you think you’ve seen it all, a one-acre undeveloped parcel lies waiting—ideal for a vineyard, sculpture garden, or your boldest vision. This is more than real estate, it’s inheritance, legacy, and one-of-a-kind.
