Set on over 1.5 private acres at the end of a quiet cul-de-sac in Crystal Mountain, this custom limestone estate in Eanes ISD offers rare scale, craftsmanship, and sweeping Hill Country surroundings. Tucked back from the street, the home makes an immediate impression with its circular drive, manicured grounds, and timeless stone facade. Inside, architectural detail and thoughtful design define the main level. A grand entry opens to hardwood floors, arched transitions, and beautifully crafted spaces, including a private office/library with floor-to-ceiling built-ins. The formal dining room flows through a butler's pantry into the spacious kitchen, breakfast area, and living room - designed for both elegant entertaining and everyday living. A sitting room with a fireplace plus a living room with a fireplace adds warmth and architectural character, while a light-filled den/sunroom off the kitchen offers a peaceful retreat. A built-in desk and shelving, positioned near the secondary staircase, adds everyday functionality. Vaulted ceilings and expansive windows frame serene views and create seamless indoor-outdoor flow. The primary suite is privately positioned with a charming window alcove, patio access, and a spa-inspired bath featuring dual vanities, a soaking tub, a walk-in shower, and generous closet space. Upstairs, a large game room and separate media/bonus room provide flexibility, along with three spacious bedrooms and two full baths. Outdoors, the property truly stands out. A sprawling lawn, mature trees, and a resort-style pool with pergola seating and a fire pit create a private backyard oasis. The expansive covered balcony overlooks lush green space and rolling hills, offering the perfect setting for sunset evenings. A rare combination of land, privacy, and timeless craftsmanship - just minutes from the heart of Austin in the award-winning Eanes Independent School District.
