About This Home
As of July 2025Tucked into a serene 1.2-acre setting in the heart of Sonoma County's Forestville, this private oasis is a rare example of mid-century modern architecture. Designed in 1947 by renowned architect John Hans Ostwald and originally commissioned by the Kellogg family, this 3-bedroom, 2-bath residence is a masterclass in timeless design. Thoughtfully updated by the current owner with deep respect for Ostwald's original vision, the home blends iconic architectural elements such as expansive walls of glass, warm wood finishes, & seamless indoor-outdoor flow with carefully integrated modern upgrades. These include a custom-remodeled kitchen and primary bath, period restored guest bath, solar(owned), EV charging, privacy fencing, heated built-in pool and hot tub with tranquil water feature. Ostwald was known for his U-shaped floor plans centered around a pool or courtyard, creating a natural extension of indoor living into the landscape. This vision is fully realized by multiple outdoor living spaces that wrap the home, drawing the beauty of the surrounding environment into every room. This architectural gem offers rare seclusion just minutes from the cultural richness of Healdsburg, the creative charm of Sebastopol and Guerneville, and the awe-inspiring Sonoma Coast and Redwoods.
