390 Treehaven Lane, Kenwood

RARE KENWOOD PROPERTY WITH VINEYARD + MAYACAMAS VIEWS

390 Treehaven Lane is a hidden gem in the heart of Kenwood—peaceful, private, and surrounded by vineyards and mountain views.

The existing residence is a brand-new, legally oversized cottage—fully permitted and built with state-of-the-art Insulated Concrete Form (ICF) construction. This highly energy-efficient, durable design is paired with the warmth of an elegant modern farmhouse. Inside, vaulted ceilings, matte-textured walls, and custom-stained trim set a refined tone. Polished concrete floors, quartz counters with gold and gray veining, a farmhouse sink with Sugarloaf Mountain views, and warm beam accents add both sophistication and practicality.

The open-concept kitchen, dining, and family room flow seamlessly to a covered 750± sq ft patio designed for year-round outdoor living. With space for dining, lounging, and evenings by the firepit, daily life extends naturally outdoors. The kitchen features high-end KitchenAid appliances, a large island with under-counter lighting, and smart storage, while the spa-inspired primary suite includes a Jacuzzi soaking tub with waterfall filler, a rain shower, and a custom LED-lit vanity mirror. A second room serves flexibly as a bedroom, office, or guest space.

The flat, fully usable 1.16± acre parcel offers space to garden, plant vines, or design a pool. Low-maintenance landscaping includes stamped concrete walkways and desert rock plantings, complemented by mature trees that frame vineyard and Mayacamas mountain views.

Treehaven Lane is a legacy street where homes seldom change hands. The parcel is zoned for two residences, with utilities—including water, septic, natural gas, and electricity—already in place at the frontage. A septic tank for a future 3-bedroom home is installed, creating a streamlined path for expansion while enjoying immediate comfort in the new cottage.

Modern systems include radiant floor heating (stubbed), mini-split climate control, a high-efficiency heat pump water heater, solar skylights with automated blinds, a fully sprinklered interior, and an EV charger. RV hookups add even more flexibility.

Located just a block from Highway 12 and a short stroll to Kenwood’s dining and tasting rooms, the property blends convenience with privacy. San Francisco is just over an hour away, and Sonoma’s best hiking, wineries, and regional parks are at your doorstep.

390 Treehaven Lane is both a turnkey retreat and a rare opportunity for expansion—an elegant, energy-efficient farmhouse in the heart of Sonoma Valley.
