About This Property
*Open Houses: Sat 6/13 11am - 2pm + Sun 6/14 12pm - 3pm* The Trailmaster House is a newly constructed modern ranch set on 1.5 private acres in Southwest Austin, blending striking architecture with warm, livable luxury. Designed to connect refined interiors with the surrounding landscape, the home is filled with natural light and a calm, intentional flow. The main residence features 4 bedrooms, 3.5 bathrooms, a dedicated office, flexible bonus space, and a three-car garage. An attached private casita includes a full bedroom and bath, kitchenette, and separate entrance, ideal for guests, multigenerational living, or a private workspace. Inside, soaring ceilings in the living room and primary suite create an immediate sense of openness. A stunning floor-to-ceiling fireplace anchors the main living area, while oversized 10 ft sliding glass doors connect the interior to the pool and outdoor living spaces. The kitchen features Italian Calacatta Monet marble countertops, a 48-inch gas range and double oven, custom cabinetry, and a clean architectural aesthetic. The sink overlooks an atrium, creating a unique indoor-outdoor experience. A spacious butler's pantry provides additional storage and prep space. The primary suite offers a private retreat with dramatic ceiling height and a spa-inspired bath featuring floor-to-ceiling tilework. Set on a fully usable 1.5-acre lot, the property offers exceptional privacy and a peaceful retreat-like setting. Deer, foxes, and other native wildlife are frequent visitors. An existing well on site provides future potential for irrigation or water development, subject to buyer verification. Outside, enjoy a resort-style pool, outdoor shower, and expansive grounds. Located just 15 minutes from downtown Austin and zoned to Baldwin Elementary, Gorzycki Middle School, and Bowie High School. The Trailmaster House is a rare combination of new construction with 1.5 usable acres in a location just minutes from downtown Austin.
