About this property

Set within the prestigious Horizon Hills enclave and embraced by the scenic foothills of Mt. Merritt and Mount Helix, this remarkable 1.3-acre estate captures the essence of refined California living. Surrounded by lush, park-like grounds adorned with mature trees, tranquil fountains, curated gardens, and sweeping vistas across the El Cajon Valley, the property offers a rare sense of seclusion and grandeur. The 3,200+ square foot main residence is a masterful expression of timeless craftsmanship and architectural heritage, thoughtfully honoring its 1925 origins while seamlessly integrating modern luxuries. Polished hardwood floors, intricate stained-glass accents, crown-molded ceilings, bespoke vintage lighting, and multiple fireplaces create an atmosphere of warmth and distinction. The light-filled interior features dual living spaces ideal for both formal and relaxed gatherings, along with a first-floor ensuite bedroom for added flexibility. At the heart of the home, the chef’s kitchen is both elegant and highly functional—appointed with a double Sub-Zero refrigerator and freezer, farmhouse sink, center island, skylights, a new Dacor smart oven and microwave, and a Kenmore Pro six-burner range. An adjacent sitting and dining area provides an intimate setting for entertaining. Upstairs, the primary suite is a true sanctuary, complete with dual walk-in closets, a two-sided fireplace, and a spa-inspired marble bath featuring a jetted soaking tub. Additional bedrooms share a spacious Jack-and-Jill bath, while an expansive multi-purpose room offers versatility for hobbies, laundry, or creative pursuits. Outdoors, the estate transforms into a private resort, showcasing a custom pool with waterfall and slide, umbrella stations, and generous Trex decking—an extraordinary backdrop for grand-scale entertaining or serene sunset evenings in complete privacy. A sweeping wraparound drive introduces the estate, offering effortless access and abundant parking for automobiles, recreational vehicles, boats, and prized collections alike—complemented by a private basketball court for recreation. A detached guest residence of approximately 700 square feet, complete with a full kitchen, provides refined accommodations for extended family, guests, or the opportunity for supplemental income. Thoughtfully enhanced and meticulously maintained, the property also features newer windows, generous storage throughout, a workshop with dedicated 220V service, central vacuum, updated HVAC, rich stone and hardwood flooring, multiple outdoor patios, and a pre-poured spa slab ready for installation. With the option to convert the detached garage to suit your needs, the estate offers exceptional flexibility. Privately set yet just moments from daily conveniences, this Horizon Hills sanctuary masterfully blends historic character, curated updates, and resort-caliber amenities into a truly distinctive offering.
