Castle Road Estate • Sonoma, CA


Firmly rooted in the land’s storied past and influenced by both history and contemporary architecture, this private estate is situated on prime wine country soil with unparalleled views of the San Francisco Bay Area.

With multiple homes and land parcels, the estate and surrounding compound has numerous amenities and styles that maximize this exquisite location nestled behind the gates of Bartholomew Park Winery, minutes from the Sonoma Plaza. 

The primary residence, Agave House, is a contemporary sanctuary and work of art.  Inspired by famed architect Luis Barragán, the impressive ochre-walled retreat was architecturally executed by Robert Zinkhan with interiors designed by the renowned Orlando Diaz-Azcuy and Greg Stewart of ODA Design Associates. This impressive residence is an expression of traditional Mexican architecture, including delightful elements of surprise and whimsy, with minimalist sensibilities. Bold in presence and style, yet utterly livable in form and function, this home is a marriage of curated design, and accessible country living. 

In total, the 130 +/- acre estate includes Agave house completed in 2005, as well as a historic 5 bedroom Farmhouse circa 1905; a car barn with space for 6 cars plus an expansive workshop, workout room and mudroom with 1 bedroom apartment above; an art studio, pool and pool house with glamorous pool deck surrounded by old-growth palm trees, and 7.5 +/- acres of cabernet vineyards. 

The Agave House, original Farmhouse and outbuildings are located behind Bartholomew Park Winery. A grand pool and private springs remain today, located along the Agave Creek and close to the Arroyo Seco Creek, and long-overgrown donkey trails once used by the Sonoma Mission’s padres as their overland route to the Napa Valley. This land is steeped in the narratives of Sonoma’s remarkable history.

Captivating, panoramic views of the entire Bay Area are visible both from Agave and the Farmhouse. But the unobstructed vista from the dining pavilion and breakfast deck in the contemporary Agave home offers a prized expanse showcasing San Pablo Bay, Mt. Tamalpais, 3 bridges including the towers of the Golden Gate, and a lovely cityscape of the San Francisco skyline where downtown buildings and Sutro Towers are recognizable.  Similar views, with a slightly different perspective, provide the stunning backdrop from the upper property, especially from the upstairs Farmhouse windows and balcony.

This is a rare combination of contemporary style and curated design on a historic parcel with stunning views, rich with natural resources. A unique blend of residential, recreational, agricultural and workspace allows this property to adapt to many needs and living arrangements. Ideally suited as a family retreat or multi-generational estate, or a creative enclave for like-minded artists or entrepreneurs, this land has an array of possibilities.


A contemporary sanctuary and work of art, this gated estate was inspired by famed architect Luis Barragán and built by Robert Zinkhan, with interiors by the renowned Orlando Diaz-Azcuy. The impressive 7631 +/- sq ft residence with three private en-suite bedrooms is a modern expression of traditional Mexican architecture. Bold in style, yet utterly livable, this home is a marriage of curated design and accessible country living. Captivating, panoramic views of the Bay Area create the perfect backdrop for the home’s indoor/outdoor layout. Gourmet chef’s kitchen, butler’s pantry and central courtyard with infinity pool make this home ideal for entertaining.

Beneath Agave House is an enchanting, stone-walled cellar with cement floors, French drains and zinc tables used for making wine or curing olives. Fully utilitarian, yet easily transformed to an enchanting event space, there is a designated kitchen and charming half bath. A library for cataloging wine is tucked into a cozy corner, also an intimate dining area for 4-6. Overall the cellar is spacious enough to seat 80-90. Access to the bougainvillea trellis adds open-air options to the unique space.  Thriving gardens plus Manzanillo olive, pomegranate and citrus orchards create a beautiful backdrop to the Bocce court and outdoor sitting area. 


Built in a secluded valley with stunning views, the wisteria-covered red farmhouse, built in 1905, has 4 upstairs bedrooms and master bedroom on the first floor. With original and vintage windows throughout, an enclosed sun porch and an additional screened dining porch that comfortably seats 12, a large kitchen and gorgeous views of the valley floor and the bay beyond, it is as picturesque and inviting as a wine country farmhouse can be. Sunny and bright, recently painted and carpeted, it is a fresh space waiting for new memories to be made. The pool and pool house below are surrounded by majestic palm trees and flagstone deck.


Inspired by a love of classic cars, the 6+ car barn was built for restoration projects and to house an antique car collection. Extensive storage and floor space offers a flexible barn/garage with ample built-ins to store and organize tools or equipment. A full bath, closet and utility/mud room with washer/dryer makes it ideal for mechanics, artists or vineyard workers to tidy up onsite.

Above the car barn is a darling 1 bedroom apartment with pitched, open beam ceilings, French doors to an upstairs covered porch, and wood burning stove. There is also a small kitchenette, treetop bedroom with high ceilings, and full bath.
