$9.9 Million Boerne Estate Offers 46 Acres of Unrestricted Texas Hill Country Living Beside Cordillera Ranch

Set just outside Cordillera Ranch, the 10,621-square-foot compound pairs sweeping Hill Country views with a private guest residence, resort-style pool, stocked fishing pond, wine cellar and a hidden Fort Knox safe room—all without the neighboring community’s HOA restrictions.

Privacy is often measured in gates and landscaping in the luxury housing market. At 186 Joe Klar Road in Boerne, Texas, it is measured in acres.

The newly listed $9.9 million estate spreads across approximately 45.78 acres immediately adjacent to Cordillera Ranch, placing its owners beside one of the Texas Hill Country’s best-known luxury communities while remaining outside its homeowners association and associated annual fees.

Built in 2018, the property encompasses 10,621 square feet between its principal living areas and guest accommodations, with six bedrooms and eight bathrooms overall. Yet its scale tells only part of the story. Long-range views stretch toward the Twin Sisters peaks, mature oak trees punctuate the landscape, and a stocked fishing pond and resort-style pool turn the acreage into a private recreational retreat.

Listing agent Tamara Strait of San Antonio Portfolio KW RE describes the property in the listing as a rare opportunity to combine the location and prestige associated with Cordillera Ranch with the freedom of a private, unrestricted luxury ranch.

Nearly 46 Acres Beside Cordillera Ranch

The estate’s location is central to its appeal.

Cordillera Ranch has become synonymous with high-end Hill Country living near Boerne, but 186 Joe Klar Road occupies a different position: directly adjacent to the community while sitting on its own substantial acreage.

That distinction gives the property a degree of independence difficult to find among master-planned luxury communities. Rather than being defined primarily by neighborhood amenities, the estate creates a self-contained environment where the land itself becomes one of the principal luxuries.

Across roughly 46 acres, the landscape opens to broad Hill Country vistas, including distant views toward the Twin Sisters. Mature oaks and abundant wildlife reinforce the sense of separation, even though downtown Boerne remains only minutes away.

A Main Residence Built Around the Hill Country Views

The principal residence was conceived around two sometimes competing priorities: comfortable everyday living and entertaining on a much larger scale.

Its main living quarters contain four bedrooms, two private offices and four-and-a-half bathrooms, with soaring ceilings and substantial expanses of glass drawing the surrounding landscape into the interiors.

The chef’s kitchen serves as a central gathering point, while expansive living spaces provide room for both formal occasions and relaxed family life. Throughout the house, sightlines have been positioned to take advantage of the long-distance Hill Country views.

The primary suite functions as a private retreat of its own, complete with a large boutique-style dressing room and an outlook across the acreage.

According to the property’s marketing, the home was deliberately planned to accommodate family life without compromising the ability to host at scale—a theme that becomes even more apparent in its most unusual interior space.

A 1,120-Square-Foot Trophy Room Anchors the Estate

At 28 by 40 feet, the estate’s trophy and bonus room is closer in scale to a private club lounge than a conventional residential game room.

A dramatic 360-degree fireplace occupies the center of the space, allowing gathering areas to form around it while maintaining views toward the pool and grounds.

An enclosed wine cellar and walk-behind wet bar transform the room into a substantial entertaining venue. Hidden from view is another particularly unusual amenity: a Fort Knox safe room, integrated discreetly into the space.

The combination reflects the property’s larger philosophy. Its amenities are not simply added as isolated features; they are arranged around how the estate might actually function during gatherings, extended family visits or longer stays.

A Separate Guest Residence Makes Multigenerational Living Possible

On the opposite side of the trophy room sits a private guest residence, creating meaningful separation from the principal household without isolating visitors in a detached building.

The guest quarters contain two bedrooms, two full bathrooms and a dedicated office, providing enough space to operate as an independent residence.

That configuration gives the estate considerably more flexibility than a conventional guest suite. Extended family could remain for months rather than days, adult children could maintain their own living environment, or the space could accommodate guests and household staff while preserving privacy for the owners.

Together with the four-bedroom principal residence, it brings the property’s total accommodation to six bedrooms.

Strait’s listing emphasizes this flexibility as part of the estate’s appeal as a private family compound rather than simply a large luxury home.

The Backyard Functions Like a Private Hill Country Resort

Beyond the glass, the estate transitions into a series of outdoor spaces designed around the Texas climate.

A substantial resort-style swimming pool forms the centerpiece, accompanied by a cabana with its own bathroom and multiple areas for lounging and entertaining. Mature trees provide natural shade, while the open acreage preserves the expansive views that define the property.

Rather than concentrating every amenity immediately around the house, the landscape extends the experience farther into the property.

The result is an environment equally suited to large celebrations, weekends centered around the pool or quieter evenings spent watching the Hill Country landscape change with the light.

A Professionally Rebuilt Fishing Pond Adds Another Layer of Recreation

One of the more unusual features lies farther into the grounds.

The estate’s stocked fishing pond was extensively rebuilt using a commercial-grade liner, which was then covered with approximately four feet of soil to maintain the appearance of a natural Texas pond while improving long-term water retention and durability.

Two aeration systems help maintain water quality, while a pair of solar-powered automatic fish feeders supports the stocked ecosystem.

It is a detail that illustrates how thoroughly the acreage has been developed for recreation. Owners can move from swimming and entertaining near the residence to fishing and wildlife viewing without leaving their property.

For a buyer seeking a true luxury ranch rather than a suburban estate on an oversized lot, that distinction matters.

Modern Infrastructure Behind the Ranch Lifestyle

The rural atmosphere does not mean sacrificing modern resilience.

Two Generac whole-home generators provide backup power, supporting the residence during outages and adding another layer of independence to the compound.

The combination of infrastructure, substantial acreage and dedicated guest accommodations makes the property particularly suited to buyers who want a primary residence capable of functioning autonomously while remaining within convenient reach of Boerne and San Antonio.

Its location also provides a compelling middle ground: sufficiently removed to deliver genuine privacy, but not so remote that dining, shopping, schools and city services become inconvenient.

Why the Estate Stands Apart in the Boerne Luxury Market

Boerne has increasingly become a destination for buyers seeking an alternative to conventional luxury neighborhoods around San Antonio.

The appeal is straightforward: rolling terrain, mature trees, substantial acreage and a recognizable Hill Country identity, combined with access to the economic and cultural infrastructure of the San Antonio metropolitan area.

At 186 Joe Klar Road, those qualities converge on an unusually large scale.

The approximately 46-acre setting, neighboring Cordillera Ranch location, guest residence, substantial entertainment facilities and recreational landscape give the property characteristics of both a luxury estate and a private ranch.

The property was listed for $9.9 million on August 5, 2026. It had previously been offered for $8.85 million in 2022 before selling later that year, according to the supplied listing history.

As Strait’s marketing puts it, the offering combines the prestige and location of Cordillera Ranch with the independence of a private luxury ranch—a combination that is exceptionally difficult to reproduce.
