Welcome to the Tamayo Estate and Vineyard, an extraordinary 11.34-acre retreat nestled in Brentwood's prestigious gated enclave. This Mediterranean-inspired estate boasts nearly 6,600 SqFt of refined living space and approximately 3,000 SqFt of covered patios, offering seamless indoor-outdoor living. The property features expansive Syrah vineyards, benefiting from pre-1914 water rights via the Byron Irrigation District. Inside, a grand foyer leads to spacious living areas, a state-of-the-art movie theater, and private quarters ideal for guests or staff. The gourmet kitchen, adorned with stone countertops and premium appliances, caters to culinary enthusiasts. Owned solar panels reduce the estate's environmental footprint. Recent renovations have enhanced the property's elegance, while the in-ground pool and spa provide a resort-like ambiance. Other highlights include the 5,000 bottle wine cellar with a temperature-controlled room and the 6 car garages within a private motor court. Strategically set within a community where future homes built will be a minimum of 5,000 SqFt, the estate offers unparalleled privacy and exclusivity. Breathtaking views of Mt. Diablo serve as a picturesque backdrop. Adjacent 3 parcels available for sale, which would expand the estate to ~44 acres.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
