Set within a private Kendall County ranch just minutes from Boerne and near Cordillera Ranch, this custom Hill Country estate brings together refined residential design, exceptional ranch infrastructure, and complete privacy. Built by Mattern & Fitzgerald, the 8,107 square foot residence offers 4 bedrooms, 4 full baths, and 1 half bath, with a thoughtful layout designed to capture natural light, long property views, and a seamless connection to the surrounding land. The home is defined by floor-to-ceiling windows, European white oak floors, smooth-finished walls, custom ceiling treatments, designer lighting, and refined stone and marble selections throughout. The main living area is anchored by a stacked stone gas fireplace and opens to a chef's kitchen designed for both everyday living and elevated entertaining. Professional-grade stainless steel appliances include Wolf ranges, four ovens, a warming drawer, dual refrigerators, KitchenAid undermount appliances, two dishwashers, oversized dual islands, and breakfast bar seating. The primary suite offers a private retreat with direct patio access, custom ceiling details, extensive built-ins, dual closets, a spa-inspired bath with marble accents and separate vanities, and a dedicated exercise room. A front guest bedroom, private study, and secure gun room add function and flexibility, while two additional guest suites are positioned on the opposite side of the home, each with its own en-suite bath. A spacious game room with wet bar opens directly to the covered patio, creating an effortless transition to the outdoor living areas. Designed for year-round entertaining, the exterior features pristine landscaping, an expansive covered patio with wood-paneled ceiling accents, a fully equipped outdoor kitchen, and a resort-style pool and spa positioned to take in the surrounding ranch setting. The oversized side-entry four-car garage includes EV charging and a dedicated pet wash area. Beyond the residence, the ranch has been carefully improved for long-term use, accessibility, and ease of ownership. The land has been extensively cleared of cedar, allowing native grasses, live oaks, and hardwoods to define the park-like setting. Gently rolling, usable terrain ranges from approximately 1,280 to 1,400 feet in elevation and is cross-fenced into multiple pastures for rotational grazing. Four water wells, 45,000 gallons of water storage, multiple troughs, a newly paved one-mile entry road, and miles of improved all-weather ranch roads provide exceptional infrastructure across the property. Native whitetail, free-ranging axis, turkey, hogs, and other wildlife further enhance the ranch experience, creating a rare combination of luxury, privacy, and fully usable Hill Country land.
