Property Description

Perched in the coveted Horizon Hills enclave and nestled against the foothills of Mt. Merritt and Mount Helix, this extraordinary 1.3-acre view estate offers a rare blend of privacy, character, and modern luxury. A park-like setting with mature landscaping, fountains, gardens, and sweeping views over the El Cajon Valley sets the tone the moment you arrive. The main residence spans over 3,200 sq. ft. and showcases timeless craftsmanship, including polished hardwood flooring, stained-glass windows, crown-molded palatial ceilings, unique vintage lighting, and multiple fireplaces. The light-filled interior features two inviting living areas, a first-floor ensuite bedroom, and a designer-curated aesthetic that seamlessly complements the home’s 1925 architectural heritage. At the heart of the home is the stunning gourmet kitchen—complete with double Sub-Zero fridge and freezer, farm sink, center island, skylights, new Dacor smart oven/microwave, Kenmore Pro six-burner range, and an adjacent sitting/dining area ideal for intimate gatherings or entertaining. Upstairs, a gracious primary retreat offers two walk-in closets, a dual-sided fireplace, and a spa-inspired marble bath with a jetted soaking tub. Additional guest bedrooms share a spacious Jack-and-Jill bath, and the expansive multi-purpose room provides added flexibility for laundry, crafts, hobbies, or storage. Resort-style living continues outdoors with a beautifully built pool featuring a waterfall, slide, umbrella stations, and expansive Trex decking—perfect for hosting large gatherings or relaxing in total privacy. A wrap-around driveway, basketball court, and extensive parking accommodate vehicles, toys, boats, and RVs with ease. A detached, approximately 700 sq. ft. guest house with a full kitchen offers ideal accommodations for extended family, visitors, or rental income. Other notable highlights include new windows, ample storage throughout, workshop with dedicated 220V for equipment, central vacuum system, newer HVAC, stone and hardwood flooring, multiple patios, ready-to-install spa slab, and the option to convert the detached garage back if desired. Tucked well off the beaten path yet minutes to everyday conveniences, this meticulously cared-for estate embodies the best of Horizon Hills living—where historic charm, designer updates, and exceptional amenities come together to create a one-of-a-kind sanctuary.
