Overview

Enchanting Mt. Helix retreat with stunning sunset and skyline views, situated on a fully usable 0.68 acre lot, offering a rare blend of privacy, character, and thoughtful design. A true hidden gem, this home delivers warmth, charm, and a lifestyle that is hard to replicate. Tucked behind a long gated driveway, the property opens to expansive, functional grounds that are both beautiful and highly usable. The grounds are thoughtfully terraced to create multiple flat, usable spaces, offering versatility for entertaining, recreation, expansion, or future additions. Four separate backyard areas are intentionally designed, each offering its own sense of retreat and serenity. The home has been fully remodeled with curated design accents by Decorative Artist Cassandra Schramm. A limewash exterior with farmhouse paneling sets the tone. Inside, you will find refinished original hardwood floors, curved ceilings with vintage texture, custom stone fireplaces, custom casement cottage windows and French doors throughout, and a blend of French and Italian inspired finishes. The main level features a spacious primary en-suite with a walk-in closet and a beautifully designed bathroom showcasing custom Carrera marble, dual sinks, and a garden window overlooking the grounds. The kitchen is a true focal point, complete with custom butcher block countertops, beveled subway tile, custom tile paint, blue cabinetry with designer hardware, and premium appliances. A charming Dutch door connects effortlessly to the outdoor spaces, enhancing indoor outdoor flow. Additional design details include custom painted barn doors sourced from a historic hotel in Mexico, and a guest bathroom featuring basket weave marble, Anthropologie wallpaper, and a marble and brass sink. Luxury fixtures and European style toilets elevate each bathroom. The lower level offers a secondary living space with a custom fireplace, two bedrooms, a full bath with direct pool access, a wine room, and flexible space ideal for a gym, studio, or home office. An attached studio, sharing only a common wall with the garage, includes a full bathroom, offering additional versatility for guest quarters, office use, or creative space. Outdoor living is unmatched. The expansive deck captures panoramic views of Mt. Helix and greater San Diego skyline, while the grounds are surrounded by mature, fruit bearing trees including ready to enjoy peaches, a plum and peach cocktail tree, both Fuerte and Hass avocados, almond, tangelo, Meyer lemon, mandarin orange, lime, apricot, and mulberry. Jasmine, roses, and bougainvillea further enhance the setting, while an expansive garden area creates the opportunity for a true farm to table experience. The fully usable acreage allows for a wide range of possibilities, including a future pickleball court, additional structures, or a private event space. Designed for entertaining, the property features a sparkling pool and spa, multiple flagstone patios, and large open areas to host at scale without sacrificing privacy. Additional highlights include new copper plumbing, new sewer line, solar, new HVAC systems on each level, turf throughout for low maintenance living, walk-in closets in both the primary and guest bedroom, and ample parking for RVs, boats, and more. With potential for multiple ADU configurations, this property offers flexibility for income, extended living, or long term expansion. A rare opportunity to own a truly special Mt. Helix estate where usable land, design, and lifestyle come together in a way that is incredibly hard to find in San Diego.
