Welcome to a property that truly has it all - space, sophistication, and smart sustainability - all nestled in the Texas Hill Country. From the moment you arrive at 16227 San Cayetano, you'll sense the privacy, scale, and luxury this one-of-a-kind estate delivers. Located in the gated community of Retablo Ranch in Helotes, this 2005 custom-built home by J. Long Builder sits on 8.26 acres and offers 5,577 square feet of refined living space designed for both entertaining and everyday comfort, three living areas, formal and casual dining, a dedicated study, and an upstairs game room. The spacious main-level primary suite includes a sitting area, exterior access, a large walk-in closet, and a spa-like bath with garden tub, separate shower, and dual vanities. The chef's kitchen is a standout with its spacious layout, custom cabinetry, granite countertops, walk-in pantry, gas cooktop, double ovens, and oversized island-built for gatherings of all sizes. Upstairs, you'll find three additional bedrooms and a rare walk-in holiday closet designed for convenient seasonal storage. Step outside to your own private resort. The backyard features an in-ground pool and new above ground spa, full outdoor kitchen with gas grill, covered cabana, mature trees, spacious patios, and a private 384 sq ft outdoor shower area-perfect for rinsing off after a swim or a day in the sun. One of the property's most impressive features is its expansive garage capacity: a 4-car attached garage plus a large detached workshop with additional enclosed parking-ideal for car collectors, hobbyists, or storing recreational gear. A fully paid-off solar energy system with Tesla Power wall battery backups-a $160,000 upgrade-provides energy efficiency, utility savings, and reliable backup power. With three HVAC units, a metal roof, private well, aerobic septic system, and double-pane windows, every detail is built for performance and peace of mind. This is more than a home-it's a Hill Country lifestyle!
