From the moment you arrive, the welcoming front porch and striking curb appeal set the tone for what awaits inside.This exceptional home underwent an extensive remodel/addition in 2020 by a local design-build firm — envisioned as a forever home, and it shows in every detail.Step inside to soaring beamed ceilings, wood paneling, floor-to-ceiling windows, and a statement stone gas fireplace anchoring the living and dining rooms.The kitchen is the heart of it all — expansive stone island, Viking gas range, beverage fridge, and a fully outfitted butler's pantry with extra freezers for those Costco runs.The primary suite is a true retreat: spa bath with soaking tub, heated floors, glass shower, custom walk-in closet, and direct access to a private deck and hot tub for ultimate relaxation.Three additional spacious bedrooms and a beautifully updated full bath complete the main floor.Upstairs, bonus space abounds — an expansive great room with kitchenette, gas fireplace, and temp-controlled wine cellar (800+ bottles!) plus media center, sunny big bedroom, new ¾ bath, and private office.Outside, professional landscaping with lighting, a flat grassy yard, stone patio, and sauna create a private, fenced backyard oasis.The deep three-car garage flows into a mudroom with full-height cubbies...See More
