16 Days on Market

Fully gated. A 40-by-20-foot pool. Park-like grounds with heritage trees and rose gardens. An 1918 estate on the Kentfield/Ross border where entering through the gate feels, unmistakably, like leaving California for the countryside of southern France. Sixteen days on market.

There is a category of Marin County estate that does not negotiate with the present — a property that was built for permanence, maintained with devotion, and offered to the market not because its time has passed but because the next chapter requires a new custodian. 315 Kent Avenue is precisely this: a 1918 property in the sunny flats of Kentfield, on the border with Ross, whose park-like grounds and architectural presence place it in the Architectural Digest conversation without irony or qualification.

The gate closes behind you and the city disappears. Heritage trees and established rose gardens frame the approach; the mature landscaping of a property that has been tended for over a century delivers the layered quality that new planting can never replicate. The 40-by-20-foot pool and spacious yard create the outdoor infrastructure of an estate that was built for the NorCal lifestyle long before the phrase existed. A large courtyard supplements the two-car garage with ample guest parking — a rarity in residential Kentfield.

The main home delivers four bedrooms and four baths across two levels of lovingly preserved architecture: a state-of-the-art living room with exposed beam ceilings, wall paneling, and a stone fireplace that is the room's undeniable center of gravity; a charming recreation room with a pellet stove and direct backyard access; a formal dining room; two powder rooms on the main level; and a cottage-style kitchen that honors the building's character. Upstairs, four bedrooms and two full baths feature domed ceilings, double-hung windows, custom built-ins, and hardwood floors throughout.

The guest cottage: A self-contained one-bedroom, one-bath cottage on the property — completely independent from the main residence — expands the estate's functionality into multigenerational living, hosted guests, or a private creative studio. In the Kentfield flats, a property that offers both a main residence and an independent guest cottage is a category unto itself.

Closed at $3,125,000 — $1,054 per square foot — in 16 days. Lovingly preserved and cherished for generations, 315 Kent Avenue awaited its next connoisseur of legacy architecture.

Kentfield Flats
Marin's Sunniest Premium Address
The Kentfield flats — warm, flat, close to top-rated schools and Woodlands Market — represent one of Marin County's most consistently sought-after residential positions for families, consistently commanding among the highest per-foot prices in the county.
1918 Estate
Generational Rarity
A fully gated 1918 estate with heritage trees, rose gardens, guest cottage, and a 40x20 pool in the Kentfield flats trades perhaps once per decade. Scarcity at this level is independent of broader market conditions.
Guest Cottage
Estate Multiplier
A self-contained one-bedroom guest cottage on the property expands the estate's daily functional value dramatically — rental income, multigenerational living, creative studio — and is an asset the standard Kentfield single-family home simply cannot offer.
16 Days on Market
Decisive
A 16-day close at $3,125,000 for an 1918 Kentfield flats estate with pool, guest cottage, and heritage grounds confirms the depth of buyer demand for irreplaceable legacy properties in central Marin when they are priced correctly.
