A rare opportunity for Eichler purists, 4130 Wilson masterfully balances preserved original character with thoughtful modern improvements. Retaining its original kitchen, bath and mahogany panels, this home showcases the timeless design principles that have made Joseph Eichler's mid-century modern homes enduring icons of California architecture. The recently enhanced backyard has been transformed into a private retreat designed for year-round enjoyment. A stunning 15' x 30' saltwater swimming pool with integrated spa, retractable cover, and updated hardscaping serves as the showpiece of the outdoor space. Thoughtfully curated landscaping includes striking desertscape plantings, mature fruit trees, turf, and a drip irrigation system, all framed by a new rear fence and gate, creating a beautiful, low-maintenance setting ideal for both entertaining and relaxing. Inside, warm mid-century character shines throughout. Rich mahogany paneling, mahogany interior doors, and the original Eichler kitchen, bath, and laundry spaces celebrate the home's architectural heritage, while the luxurious radiant floor heating system delivers the comfort that Eichler owners have long appreciated. Recent renovations include porcelain tile flooring in the kitchen and laundry room, a refreshed hall bath vanity, fresh interior paint, and new carpeting in the bedroom wing. Modern convenience has been thoughtfully incorporated with new appliances including a Samsung Bespoke refrigerator, updated dishwasher, washer/dryer set, and water heater. The garage workshop has also been significantly upgraded with enhanced electrical service, including 220-volt outlets, a rotary phase converter capable of operating 220-volt three-phase equipment, and an additional dedicated 20-amp outlet-exceptional features for heavy duty machinery. Additional peace of mind comes from major system improvements completed, including a newer roof installed approximately six years ago and a radiant heating boiler installed approximately ten years ago. Situated in the vibrant Rancho Del Diablo community, residents enjoy convenient access to BART, shopping, dining, parks, hiking trails, and major commuter routes. Combining iconic Eichler architecture, preserved original character, meaningful upgrades, and exceptional outdoor living, 4130 Wilson presents a rare opportunity to experience authentic mid-century modern living while stewarding a remarkable piece of architectural history.
