At the heart of the home, the beautifully updated kitchen is designed for everyday living and entertaining, featuring gas cooking, custom cabinetry, a custom exhaust hood and upgraded refrigerator, oven, microwave and dishwasher. The living areas flow effortlessly into a light-filled sunroom and out to the expansive deck overlooking the in-ground saltwater pool and hot tub, creating a seamless connection between indoor and outdoor living. Upstairs, the enormous primary suite is a true private retreat, complete with a 16' x 13' sitting room and incredible 20' x 10' walk-in closet. Two additional bedrooms share a completely renovated Jack and Jill full bath, while the fourth bedroom enjoys its own private full bath, creating an ideal layout for family and guests.

Outside, your own private resort awaits. The expansive deck, stamped-concrete patio and extended pool surround offer multiple areas for dining, entertaining and relaxing, all centered around the HEATED in-ground saltwater pool, hot tub and outdoor speaker system. Extensive improvements to the grounds include grading and topsoil, new lawn, expanded fencing and strategically planted trees that enhance privacy while complementing the property's beautiful setting and views. The renovations extend well beyond cosmetic finishes and include a newer roof, new sewer line, newer hot water heater, expanded driveway and parking area, plus a beautifully refreshed three-car garage with epoxy flooring, fresh paint and an electric-vehicle charging station. Additional improvements include new flooring throughout much of the first floor, refinished and upgraded staircases, two updated main-level powder rooms, extensive interior painting from ceilings to trim and doors, and high-end upgraded fixtures throughout.
