This 4-bedroom, 4-bath main residence pairs period character with modern comfort. Craftsman details, timeless proportions, and a warm, livable floor plan carry throughout the approximately 4,818 sq ft main residence. The grounds are just as special. Mature landscaping surrounds the in-ground pool, creating a private setting for afternoons outdoors, entertaining, and relaxed Sonoma living. The 3-car garage includes a convenient shower room, ideal for pool days, gardening, or a quick post-workout rinse. Above the garage, an approximately 825 sq ft carriage house offers a simple, private escape for guests, a home office, or studio. Just five blocks from Sonoma Plaza, the property is close to boutiques, tasting rooms, Michelin-starred and acclaimed restaurants, and the heart of downtown Sonoma. With approximately 4,018 sq ft in the main house plus an additional 825 sq ft carriage house and a total of 6 full bathrooms, this is a rare opportunity to own a remarkable piece of Sonoma's architectural heritage.
