In a world of cookie-cutter subdivisions and tiny backyards, Tonkawa Springs offers something increasingly rare: room to spread out, mature trees, spring-fed ponds, and a neighborhood where nature and community still take center stage.
Set beneath mature shade trees on a spacious lot, this thoughtfully updated home features four bedrooms plus two additional flex rooms that can easily serve as guest rooms, home offices, a gym, craft room, playroom, or homeschool space. Every bedroom is generously sized, and abundant storage throughout helps keep daily life organized. Recent improvements blend comfort and character, including triple-pane vinyl windows, beautiful acacia wood flooring, and a chef-inspired kitchen equipped with a Fratelli Onofri double gas range, built-in wall oven, and microwave. The gameroom showcases reclaimed wood from Camp Mabry, creating a one-of-a-kind focal point.
The backyard was designed for gathering. Whether you're hosting pool parties, roasting marshmallows around the firepit, watching the game from the cabana bar, or enjoying a quiet evening beneath the heritage oak, there is room here to create memories for years to come. A large composite deck expands the entertaining space, while the magnificent heritage oak provides shade, beauty, and plenty of room for backyard adventures. For buyers seeking additional backyard privacy, landscaping or 6-foot wood privacy fencing would allow you to customize the outdoor space to your preferences. (But you may find you WANT to get to know the neighbors-they are pretty great!)
Tonkawa Springs remains one of Round Rock's most distinctive neighborhoods, known for its spring-fed ponds, abundant wildlife, mature trees, oversized homesites, and strong sense of community—all just minutes from top-rated schools, shopping, dining, and major employers. Opportunities in this neighborhood don't come up very often, so don't miss your chance!
