About this home
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. Metal roof, AC, tankless water heaters, it's all been done. Walkable to top-ranked MI schools, Pioneer Park, and South End shopping. Move in and enjoy the good life, this one is truly rare.
