About This Home

9945 Alto Drive is an architectural retreat nestled in the coveted hills of Mt. Helix, where sweeping views, elevated privacy, and creative possibility converge. This expansive 5-bedroom, 5-bath home offers over 5,000 sq ft, which includes a large 1-bedroom and 1-bathroom ADU-like retreat upstairs. It’s bathed in natural light and designed to inspire. From its dramatic vaulted and wood-beam ceilings and statement, brand-new, custom-built kitchen to its outdoor oasis for entertaining, gardening, and custom fire-fit and seating area for breathtaking sunset views, every space invites you to breathe, entertain, and envision what’s next. The layout is flexible and ready to evolve and here’s the magic: the seller is offering custom layout consultation and a potential design-build credit with purchase. Whether you’re dreaming of a reimagined primary suite downstairs or a bespoke live-work sanctuary, the framework is here. You bring the vision; we’ll help you build it. The terraced backyard offers multiple outdoor zones for entertaining, gardening, or simply taking in the sunset with a glass of wine poolside. Perched high above the city bustle but just minutes from the best of La Mesa, this home blends tranquil luxury with modern convenience. This is not your standard home and that’s exactly the point. Private showings available. Seller open to creative offers. Bring your ideas, your dreams, and your designer.
