    What's special

    Dedicated officeStunning marble countertopsMarble backsplash
    Recently renovated just two years ago, this beautifully updated home is designed with entertaining in mind. Engineered flooring runs throughout the entire home, with the exception of the bathrooms, creating a seamless and modern feel. The kitchen features stunning marble countertops and a marble backsplash that adds a touch of luxury. The cabinetry is from Semihandmade, known for its high-quality, design-forward cabinet fronts that pair with modular systems-allowing you to easily update styles, swap finishes, or reconfigure elements without the cost and disruption of a full kitchen remodel. A double gas oven and gas cooktop make the kitchen both functional and inviting, while the gas fireplace creates the perfect cozy atmosphere for relaxing movie nights at home. The home offers 3 spacious bedrooms plus a dedicated office, with a thoughtful layout that ensures privacy-no bedroom shares a wall with another. Bathrooms have been refreshed with new lighting, and stylish shiplap accents enhance both the entryway and main living area. Major exterior upgrades include a recently installed, impact-resistant shingle roof (which may qualify for insurance discounts), as well as recently replaced fascia and soffits, all freshly painted. Situated in the highly desirable Circle C area of Austin, this home is walkable to one of the city's top-rated elementary schools. The property is surrounded by mature trees, including two beautiful oaks and three towering 60-foot trees in the backyard, creating a serene and private outdoor retreat. Additional highlights include extra flooring, paint, and tile that will convey with the home-perfect for future touch-ups. With wonderful neighbors and a peaceful setting, this home was truly intended to be a forever.
