Monticello Colleyville * Hilltop corner lot * Circular drive * Taj Mahal Quartzite island * Multiple balconies * Waterfall & pond * Wooded lot: Poised atop a picturesque hill in a prestigious enclave, this estate embodies elevated luxury, panoramic vistas, and an unrivaled corner-lot presence within Grapevine-Colleyville ISD. A stately circular drive, lush mature trees, elegant stone accents, and a sophisticated paved sitting area set a grand stage and impeccable curb appeal. Step inside to discover an exquisitely updated gourmet kitchen anchored by an expansive imported Taj Mahal Quartzite island, surrounded by custom white cabinetry, professional-grade stainless-steel appliances, double ovens, designer pendant lighting, a farmhouse sink, and an artisanal tile backsplash. Rich mahogany solid-wood floors flow seamlessly throughout the main living, dining, and formal spaces, complemented by fresh designer paint, intricate crown molding, plantation shutters, and fine custom trim. Ascend the central staircase, where a dramatic landing overlooks the foyer and guides you to a charming front deck. A spacious bonus room links two bedrooms and opens to a private rear balcony. From this vantage, take in the enchanting, secluded backyard retreat--framed by mature trees, masterfully crafted stone retaining walls, organic rockwork, a tranquil waterfall, and a serene pond below. The upstairs bedroom wing offers a suite-style haven with a separate hall entry for utmost privacy. A hidden staircase leads to a vast attic room, ideal for storage or an exclusive future living space, subject to buyer vision. Monticello's resort-style amenities include shimmering ponds and lakes, meandering walking and biking trails, playgrounds, tennis and pickleball courts, and tranquil fishing spots. Moments from upscale retail, Market Street, Life Time, Starbucks, and school campuses, this extraordinary home harmonizes timeless architecture, bespoke upgrades, and a coveted wooded sanctuary.
