Thoughtfully conceived and beautifully executed, this exceptional new construction residence offers more than 7,600 square feet of impeccably designed living space in Lexington’s coveted Sun Valley neighborhood. A two-story foyer makes an immediate impression, introducing sun-filled interiors with generous ceiling heights, large-scale windows, and wide-plank hardwood floors throughout. Elegant formal living and dining rooms lead to a spectacular chef’s kitchen centered around an oversized island, complemented by a walk-in pantry, service bar with wine refrigeration, and breakfast area opening to a private deck. The adjoining fireplaced family room is framed by custom built-ins and flows into a striking window-wrapped sitting room with a vaulted tongue-and-groove ceiling, creating one of the home’s signature architectural moments. A first-floor bedroom suite or office adds flexibility. Upstairs, the primary includes two boutique-style dressing rooms with tailored built-ins and a spa-quality bathroom. Four additional bedrooms—two en suites and a Jack-and-Jill suite—accommodate family and guests with privacy and ease. The walk-out lower level extends the living space with a recreation lounge, dedicated theatre room, home gym, and private bedroom suite. Outside, professionally landscaped grounds unfold across nearly an acre of level lawn with classic stone walls and lush, layered plantings. Rows of Green Giant arborvitae establish an attractive year-round privacy screen, while a granite patio and deck enhance a sprawling backyard with ample room for a future pool. Natural gas service—an increasingly rare amenity in Lexington’s newest luxury homes—adds to the property’s distinction. A truly custom residence where refined finishes, timeless character, and an unparalleled setting come together to create a legacy home to be treasured for generations.
