The Fieldhaven Estate in Alamo, a sprawling French-country mega-compound with its own aviary, 20-car barn, geese fountain and rope-bridge treehouse, has finally traded hands for $21.5 million. The 21-acre spread spent years being relisted and re-priced before landing a buyer, a figure that comes close to the county’s all-time residential high. Local brokers say the deal highlights just how much demand there is for large, private estates that are still within commuting distance of Bay Area tech hubs.
What’s on the grounds
Fieldhaven sits on roughly 21 acres and is anchored by a main residence of about 23,314 square feet, with 10 bedrooms and 22 bathrooms. Two guesthouses bring the total bedroom count across the compound to 22, according to the San Francisco Chronicle. Amenities are about what you would expect from a trophy property of this scale, and then some: two pools, a movie theater, a wine cellar, and an aviary created by a zoo curator, plus outdoor flourishes like an 1800s geese fountain. There is also a dedicated car barn that can accommodate about two dozen vehicles and a solar field that is intended to make the estate largely self-sufficient.
Sale details and price history
Public MLS records show the estate closed at $21.5 million last Friday, after more than two years on the market and a series of price cuts, according to MLSListings. The real estate outlet The Real Deal reported that the buyers are an unnamed East Bay family and noted that the sale lands close to the county’s record for a residential transaction.
Built, donated and flipped
The estate was developed by PeopleSoft and Workday co-founder David Duffield and completed around 2012. The build and related work have been reported as costing well into the tens of millions. Duffield sold Fieldhaven in 2020 for about $19 million, and listing materials and local coverage say the next owner invested several million more in upgrades before bringing it back to market. These earlier details are laid out by Compass.
What agents say about the luxury market
“The overall luxury market in the East Bay is extremely strong,” listing agent Marilee Headen said, telling The Real Deal that agents are seeing increased buying power from San Francisco and Silicon Valley clients tied to the AI boom. Brokers add that a tight supply of true trophy estates is prompting well-heeled buyers to move fast when properties like Fieldhaven come up for sale. That setup, they say, helps explain why listings that once looked ambitiously priced are now closing at numbers that would have raised eyebrows even a year ago.
With its heavy emphasis on privacy, acreage and hand-crafted details, Fieldhaven is likely to stay out of public view for the foreseeable future. Records and local sources identify the new owners only as an unnamed family. For the broader market, the sale is a pointed reminder that demand at the ultra-high end of the Bay Area remains vigorous even as more modest segments show signs of cooling.
