Stone Canyon Ranch — boasting a total of nearly 13,000 square feet on 10,000 acres — is listed for $32 million. The property is home not just to the gorgeous main mansion and private guest residencies, but also extensive equestrian facilities.

George R. Roberts is known primarily as a billionaire financier, with much of his success coming through his being an original partner in the firm Kohlberg Kravis Roberts. He originally purchased this estate in the mid-1990s, with one central goal being to the property for his wife, who was an award-winning equestrienne and horse breeder.

The California property was the perfect location and would be designed to host a world-class equestrian facility in the San Benito River Valley, where his wife bred, raised, and trained award-winning American Saddlebreds for almost a decade.

The equestrian facility was just one design component; San Francisco architect Ugo Sap was brought on to design the property, which also includes vineyards, agricultural features, and grazing land in addition to the primary mansion.

The primary residence follows Ugo Sap’s contemporary theme. This mansion covers 7,900 square feet and is supplemented with an additional 5,000 square feet that make up the neighboring private guest residences. All of these spaces channel the elegant contrasts of open and airy spaces embellished with rich materials and finishes.

The houses are all designed with expansive high ceilings, stunning stone fireplaces, and custom cabinetry. Other features include slate-tile roofs from France, limestone flooring from Italy, beautiful trellises built from Alaskan cedar, and extensive low-voltage lighting.

Outside, the main residence sits atop a gentle rise, which grants it 360-degree panoramic views not just of the surrounding property, but also of the valley beyond it.

The equestrian facilities are equally breathtaking. Features include five horse barns, two expansive riding arenas as well as two separate training arenas, and a hay barn. The main horse barn hosts 14 stalls and two sets of living quarters and is situated across two sections — the Lower Compound and the River Compound. The interior is of course, top-notch.

The stalls are wood-partitioned with rubber tile floors, and the wood ceiling lays over a steel structural frame. The other horse barns are built in a similar structure, with the second-largest, the Mare Barn, having three stalls, storage space, a tack room, and an incubator room, as well as an on-site one-bedroom apartment.

The sprawling California Ranch, dubbed Stone Canyon Ranch, is both a stunning home and a world-class equestrian facility. The property covers nearly 13,000 square feet of living space between the main house and the guest residences which sit on 10,000 acres of land, with panoramic views of the valley and dozens of other features.

Commissioned by billionaire George R. Roberts, designed by San Francisco’s Ugo Sap, and nestled on the banks of the San Benito River in Paicines, California, the elegant estate is now on the market, listed at $32 million.
