about this property
∎
Nestled on two scenic acres in the hills of Cotati, this exceptional Wine Country estate masterfully blends rustic elegance with luxurious comfort. Completed in 2018, the property features a beautifully designed three-bedroom, three-bath main residence (approx. 3,418± sq. ft.), and a two-bedroom, two-bath guest cottage (approx. 840± sq. ft.), offering two remarkable year-round homes or vacation getaways in the heart of Sonoma County.
Inspired by the signature style of acclaimed local architect Howard Backen—known for designing iconic properties like Solage Calistoga and Meadowood—the estate showcases refined architectural touches throughout. The main home’s striking great room features soaring open-beam ceilings with tongue-and-groove detail, wide-plank natural-oiled French oak floors, and expansive Marvin windows and doors that flood the interior with natural light.
Designed for effortless entertaining, the open-concept living space includes a stunning gas fireplace with natural stone hearth and custom oak mantle, refreshment bar with wine and beverage refrigerators, generous seating and dining areas, and a spectacular 14-foot quartz kitchen island—an inviting centerpiece for gatherings with family and friends.
The chef’s kitchen is a culinary showpiece, featuring a custom green 4-burner Blue Star range with grill, flattop, and dual ovens, subway tile backsplash with pot filler faucet, Fireclay apron-front sink, GE stainless steel appliances, and quartz countertops. Locally crafted custom cabinetry from Rhyne Design of Sebastopol enhances every space, with soft-close drawers, floating oak shelves, and ample storage.
Indoor-outdoor living is seamlessly integrated with a variety of inviting outdoor spaces: enjoy barbecues on the pergola-covered back patio with putting green, sip morning coffee in the covered breezeway, toast to special moments on the wraparound porch, view the sunset form the deck amongst the olive trees and vineyard or unwind under the stars in the spa overlooking rolling hills.
The main level also features a stylish mudroom/flex space, full bathroom, large bonus room (potential fourth bedroom), and a private wing hosting the primary suite—a serene retreat with dual sliding doors, custom walk-in closet, and spa-inspired bath complete with soaking tub, oversized walk-in shower with multiple heads, radiant-heated handmade concrete tile floors, and dual-sink quartz vanity.
Upstairs, a custom metal and oak staircase leads to two additional bedrooms connected by a Jack & Jill bathroom, plus a versatile landing with dual built-in desks and oak cabinetry.
The charming guest cottage mirrors the design excellence of the main house, with high-end finishes including a Blue Star range, quartz countertops, Carrera marble backsplash, apron-front sink, and barn-style bathroom doors. Flexible layout allows for full or partial rental, with separate entrances for each bedroom.
Agricultural Highlights:
- Vineyard planted with premium Pinot Noir clones: Pommard, Dijon, and Merry Edwards—renowned, highly sought-after varieties.
- Mature olive grove with 30+ trees that produced 50 gallons of extra virgin olive oil last year.
- 17 established fruit trees, 100+ lavender plants, and raised garden beds.
- Open-air livestock barn with water hookups and recently replaced roof.
Additional Features:
