Property Description
The Trailmaster House is a new modern ranch set on 1.5 private acres in Appaloosa Run, one of Southwest Austin's best-kept secrets. Just outside Avana, Grey Rock, Circle C South, and Meridian, this quiet enclave offers acreage, privacy, and Hill Country surroundings only 3 minutes from SH 45, 6 minutes from MoPac, and 20 minutes from downtown Austin. Designed to blend striking architecture with livable luxury, the home is filled with natural light and connected to the surrounding landscape. The main residence includes 4 bedrooms, 3.5 bathrooms, a dedicated office, flex space, and a 3-car garage. An attached private casita offers a bedroom, full bath, kitchenette, and separate entrance-ideal for guests, multigenerational living, a private office or income potential. Soaring ceilings define the living room and primary suite. A floor-to-ceiling fireplace anchors the main living area, while 10-foot sliding glass doors open to the pool and outdoor entertaining spaces. The kitchen features Italian Calacatta Monet marble countertops, a commercial gas range with double oven, and a butler's pantry. The sink overlooks a lush interior atrium, creating a rare indoor-outdoor connection. The primary suite feels like a retreat with ceiling height and spa-inspired bath featuring floor-to-ceiling tilework and boutique hotel-style finishes. The usable lot is surrounded by mature trees and natural landscaping. An existing well offers future potential for irrigation or water use, subject to buyer verification. Outside, enjoy a resort-style pool, outdoor shower, and expansive grounds for relaxing or entertaining. Deer, fox, and other native wildlife are frequent visitors. Zoned to Baldwin Elementary, Gorzycki Middle School, and Bowie High School, The Trailmaster House offers a rare combination of privacy, acreage, architecture, and convenience-a one-of-a-kind retreat hidden in plain sight.
