Introducing Greywalls, a beautifully reimagined Lake Michigan waterfront estate set on nearly two acres of meticulously maintained, parklike grounds. Among the Midwest's most exceptional homes, this retreat is tucked within the private, gated community of The Preserve at Bay Harbor. Perfectly positioned overlooking the 17th green of Bay Harbor's Links/Quarry golf course, this classic shingle-style residence captures sunrise and sunset views from nearly every room, along with 230 feet of pristine shoreline. Encompassing over 10,000 square feet, the home offers an exceptional floorplan with 6 bedrooms, 6.5 baths, and 3 fireplaces across three levels. The main level is anchored by a dramatic barrel-vaulted great room with a soaring two-story fireplace, seating areas, and expansive windows framing the lake. A double-island chef's kitchen with top-of-the-line appliances, butler's pantry, and adjoining family room with fireplace creates a seamless flow for everyday living and entertaining. Also on the main level are a dining room, study, powder room, primary suite with oversized bath and walk-in closets, laundry room, and heated three-car garage. French doors open to covered porches and decks, offering inviting spaces for lakeside entertaining or quiet retreat. The upper level features two en-suite guest bedrooms, a three-season porch, and a separate living area with sweeping lake and lawn views. The walkout lower level includes three additional en-suite guest bedrooms, a second family room with fireplace, wet bar, and direct access to patios and the beach. The grounds include a long private drive, landscaped motor court, alfresco kitchen and fireplace beneath a pergola, a main-level patio with fire pit and lake views, a beachside patio, and mature gardens. Just moments from the Bay Harbor Yacht Club, Golf Club, and Marina Village, Greywalls offers a rare combination of privacy, refinement, and natural beauty. An extraordinary expression of luxury waterfront living.
