3560 7th Ave, San Diego, CA 92103

Set adjacent to the iconic Balboa Park on a quiet street that gently culminates at the park’s coveted northwest edge, the 3500 block of Seventh Avenue offers a rare convergence of privacy, walkability, and historic significance within the heart of Marston Hills. Enclosed within a walled and gated setting, this private luxury compound is positioned along a broad, tree-lined avenue framed by mature jacarandas and a manicured grass parkway, evoking a sense of timeless elegance within a vibrant urban backdrop. Within steps of aristocratic Bankers Hill, the setting offers exceptional walkability and seamless connectivity, while the residence captures serene treetop park views from its distinguished front façade. Comprising just eight architecturally significant residences, including the iconic Marston House Museum, this intimate enclave is among San Diego’s most storied and revered residential addresses. Defined by estate-scale parcels, enduring architectural pedigree, and lush, enveloping grounds, it is widely regarded as one of the city’s most discreet and prestigious enclaves. Originally conceived in 1905 by master architect Irving Gill, widely regarded as San Diego’s most prominent and visionary architectural pioneer, this Mills Act-designated residence stands as an early and compelling expression of Prairie Modern design. Predating the Craftsman movement of the 1920s, the home exemplifies Gill’s progressive philosophy, defined by clean lines, restrained ornamentation, and a design ethos far ahead of its time. These principles are beautifully preserved in the home’s original details, including Douglas fir crown molding and baseboards set flush with the walls, along with custom hardware meticulously handcrafted by Gill himself. The residence has been thoughtfully expanded and meticulously restored under the direction of noted historic architect Kim Grant, earning widespread recognition including a feature in San Diego Magazine in 2014, as well as multiple awards for excellence in architecture and building in 2016. Spanning over 3,300 square feet, the primary residence offers five bedrooms and four bathrooms, artfully balancing historic integrity with refined contemporary living. Interiors unfold with a sense of understated sophistication, where a gracious living room and private study introduce a warm yet elevated ambiance. These spaces transition seamlessly into a great room and chef’s kitchen of exceptional caliber, appointed with quartzite surfaces, bespoke SieMatic cabinetry, and rich Douglas fir hardwood flooring. Designed to accommodate both intimate daily living and elevated entertaining, the kitchen flows effortlessly into the dining and main living areas, while a temperature-controlled wine room below provides capacity for over 500 bottles, an amenity tailored for the discerning collector. Upstairs, natural light filters through the home’s original façade windows, illuminating a serene primary suite conceived as a private sanctuary. Dual walk-in closets, a spa-inspired bath featuring a freestanding soaking tub and dramatic black marble feature wall, and direct access to a secluded terrace overlooking the pool and grounds create an atmosphere of quiet luxury. Additional sunlit bedrooms offer flexibility for guests, family, or creative pursuits, each thoughtfully positioned to maximize both privacy and natural light. Expansive Fleetwood sliding doors establish a seamless indoor-outdoor connection, opening to west-facing grounds reimagined as a private, resort-caliber retreat. Landscaping, thoughtfully designed by Betwixt Experience Design, showcases curated drought-tolerant plantings, drip irrigation, and terraced garden beds, complemented by custom concrete hardscape designed for elevated al fresco dining and entertaining. The resort-style pool, complete with integrated spa and Baja shelf, is further enhanced by an automatic electric pool cover and complemented by a dedicated pool bath and outdoor shower. An expansive front lawn and architecturally integrated retaining walls provide both structure and aesthetic harmony to the grounds. Further elevating the estate’s versatility, a detached two-story casita spanning approximately 689 square feet, with dual private entrances, offers a refined extension of the main residence. Each level is thoughtfully designed as an independent guest retreat, complete with en-suite baths, generous walk-in closets, and well-appointed living spaces, providing exceptional flexibility for extended stays, multigenerational living, or private accommodations. A two-car garage with EV charging completes the offering, delivering modern convenience with ease and discretion. This is more than a residence. It is a legacy estate, an architectural heirloom set within one of San Diego’s most irreplaceable and distinguished settings.
