Tucked behind the gates of Key Ranch, this extraordinary Mission Revival estate offers over four acres of privacy, timeless architecture, and thoughtfully designed Hill Country living. Blending old-world character with modern functionality, the property is as beautiful as it is practical. The single-story main residence spans more than 4,100 square feet and features five bedrooms, four full baths, and two powder baths. A stunning courtyard sets the tone, welcoming you into interiors filled with natural light, soaring ceilings, and carefully curated details throughout. Designed for both everyday living and effortless entertaining, the chef's kitchen is anchored by striking Macaubas quartzite countertops and outfitted with a professional-grade appliance package, including a 48-inch range, double ovens, and a built-in espresso station. The approximately 1,600-square-foot detached guest house provides exceptional flexibility with its own kitchen, living area, bedroom, full bath, and laundry-ideal for guests, multigenerational living, long-term stays, or a private retreat. Outside, resort-style amenities include a lap pool and spa, turfed backyard, dedicated dog wash station, and a three-car garage. Designed with sustainability in mind, the property features a 64,000-gallon rainwater collection system for household use, a private well dedicated to irrigation, and whole-house generators for year-round peace of mind. More than just a home, this is a legacy property where distinctive architecture, modern conveniences, and the natural beauty of the Texas Hill Country come together in one unforgettable setting.
