Set on 3 acres in West Petaluma, this reimagined estate includes a beautifully renovated main residence and detached ADU, each thoughtfully updated inside and out with a cohesive, elevated design. The main home offers 4 bedrooms, 3 bathrooms, and 2,265 square feet of open, light-filled living space, defined by clean lines, quality finishes, and careful attention to detail. Original solid wood interior doors remain as a subtle nod to the home’s original craftsmanship, seamlessly integrated into the modern interior. The open-concept layout is designed for effortless indoor-outdoor living, with natural light throughout and an easy, comfortable flow from room to room. A detached 400-square-foot ADU with a full kitchen and bathroom provides flexible space for guests, extended living, or a pool house. Outdoors, a pool and expansive grounds create a private, versatile setting with room to expand or further enhance the property. Ideally located just minutes from downtown Petaluma, this property offers the rare combination of space, privacy, and convenience in one of Sonoma County’s most sought-after settings.
