Overview

Offered for the first time ever! Built in 1958, it's a remarkably preserved midcentury original, and an increasingly rare find in today's market. Thoughtfully scaled yet rich in character, the home lives with an effortless sophistication, featuring tongue-and-groove vaulted ceilings, original lighting, and a clean, architectural aesthetic that feels both timeless and elevated. Every detail speaks to a simpler, more intentional era of design where quality, light, and proportion mattered most. It is the kind of home that feels curated without trying, refined without excess. Set on an expansive .29-acre lot backing to open green pastures, the setting is nothing short of breathtaking. Mornings begin with birdsong, evenings welcome passing deer, and the surrounding landscape offers a sense of calm, space, and connection to nature that is rarely found this close to town. And while the home itself is beautifully complete, the grounds offer an extraordinary opportunity. Large, usable parcels like this in established neighborhoods are becoming increasingly scarce. Whether you envision a pool, a guest house or ADU, a detached garage, gardens, or space for animals, the potential here is as compelling as the home itself. Buyer to verify. Just minutes from Downtown Petaluma, parks, and highly regarded schools, this property balances lifestyle, design, and future potential in a way that is truly hard to come by.
