Perched on a quiet ridge line with panoramic views stretching from Petaluma to Santa Rosa, this gated hilltop estate offers 4.5 acres of privacy, scale, and possibility. The main, single-level, residence spans nearly 5,000 sq ft with a timeless floor plan, generous proportions, and the opportunity to create a truly remarkable modern retreat. Designed for both entertaining and everyday living, the home features formal living and dining rooms, a central kitchen with custom cabinetry and stone countertops, and a relaxed family room that opens to the deck and pool. The spacious primary suite anchors its own wing with private deck access, while two additional bedrooms offer separation and comfort for family or guests. Outdoor amenities include multiple patios, a sparkling pool overlooking the valley, and a thoughtfully designed garden area with raised beds and a charming potting shed. A detached 1,200 sq ft guest house features a full kitchen, bedroom, bath, and equally stunning views, ideal for guests or extended family. Quiet, private, and filled with opportunity, this is a rare chance to reimagine a legacy property in one of Sonoma County's most inspiring view locations.
