Set within Southbury's distinguished Fox Hollow Estates, 245 Grey Rock Road is a private 2.70-acre retreat with commanding presence. Offering more than 4,100 square feet, four bedrooms, four full baths, and flexibility for a potential fifth bedroom, this impressive Colonial delivers exceptional scale across every level. A long paved driveway winds through mature, professionally landscaped grounds, creating a remarkable sense of privacy and arrival. Inside, a soaring two-story foyer leads to an extraordinary great room, where walls of glass, dual sliders, and a floor-to-ceiling stone fireplace frame the wooded setting. The entertainer's kitchen features granite countertops, a substantial center island, double ovens, abundant cabinetry, a walk-in pantry, and sun-filled dining space. Formal living and dining rooms add elegance, while a main-level den with an adjacent full bath is ideal for guests, an office, or a fifth bedroom. The primary suite offers a sitting area, oversized walk-in closet, whirlpool tub, separate shower, and double vanity. Three additional bedrooms, including a second en-suite, and a finished third-floor bonus room provide outstanding versatility. An approximately 2,000-square-foot walkout lower level with full-size windows offers remarkable expansion potential to make the home nearly 6,000sqft. A three-car garage and expansive deck with an electric awning complete the property-all minutes from I-84, Southbury's town center, shopping, dining, and parks.
