138 Yellow Bell Run Experience the pinnacle of Balcones Hill Country sophistication in this 3, 855 sq. ft. masterpiece, perfectly positioned on a premium, pie-shaped cul-de-sac lot. The striking stucco-and-stone exterior radiates curb appeal, while the three-car garage upgraded with sleek epoxy flooring and a deep-set covered porch provides a grand welcome. Inside, the functional 5-bedroom, 3.5-bath layout is a masterclass in design, featuring a secluded home office and a clever split floor plan where two bedrooms are joined by a stylish Jack-and-Jill bath. The heart of the home is a sprawling, open-concept great room anchored by a dramatic corner fireplace and framed by sweeping views of the outdoor oasis. The gourmet kitchen is a chef's dream, boasting a massive center island, a walk-in pantry, and a built-in desk that acts as the home's command center. This isn't just a standard build; the interior is elevated by high-end custom upgrades and designer accent walls that add a layer of texture and modern luxury to every room. Retreat to the main-level primary suite, a spa-like sanctuary defined by a tray ceiling, a deep soaking tub, and an upgraded luxury shower with dual vanities and expansive storage. Upstairs, a massive loft transforms into the ultimate game room or second living area, flanked by two additional secondary bedrooms for total privacy. The lifestyle extends to the outdoors, where an extended covered patio overlooks an oversized, fully fenced-in yard. Whether you're hosting a summer gala or planning a future resort-style pool and play area, this tranquil setting offers the ultimate canvas for your imagination.
