About This Home

As of January 2026

Introducing Bullfrog Farms, nearly 7 acres in Penngrove, a charming old-world town at the gateway to Wine Country. This renovated 3BD/3BA farmhouse blends country character with modern luxury, showcasing a chef's kitchen with Viking range, Thermador oven, dual Bosch dishwashers, marble island, and custom cabinetry. The open-concept great room includes a gas fireplace and custom banquette seating, while the primary suite features a spa-inspired bath with heated floors, peek-a-boo fireplace, Toto heated toilet, cedar walk-in closet, and serene views overlooking the pond. A reimagined barn, integrated into the main home with a separate entrance, offers flexible space with a gym, office, media room, flex area, and bath. Outdoors, a Brazilian hardwood deck captures the beauty of the picturesque pond and the property's retreat-like setting, complemented by a tiled patio with fans, hot tub, and outdoor shower. Additional upgrades include Marvin windows, Hardy Board siding, standing-seam metal roof, 200-amp power, and modern mound septic. Flat, usable land offers endless possibilities with easy access to Hwy 101, downtown Petaluma, and all the charm of downtown Penngrove perfect for an ideal country lifestyle.
