This is a rare opportunity to own a beautifully preserved and thoughtfully updated classic modern home designed by renowned architect Marvin DeWinter, who also designed the Grand Rapids Ford Museum. This one-of-a-kind waterfront residence is both a true architectural masterpiece and an exceptionally livable home located within the City of Grandville. The impressive living room is filled with character, featuring soaring lofted ceilings, massive windows, a wood-burning fireplace, and stunning woodwork throughout. Just off the spacious kitchen is an open dining area with room to expand, while the kitchen itself offers a large center island and views of the three-season room. A generous lakeside office features floor-to-ceiling windows overlooking the backyard and water. The luxurious owner's suite continues the home's signature style with a wall of windows, wood-beamed ceiling, brick accent wall, large walk-in closet, and a beautifully appointed private bath with a spacious corner whirlp ool tub, separate tiled shower with glass enclosure, and dual vanities. Two additional oversized bedrooms are located on the main floor and share a large full bath. Also on the main level are a laundry room, abundant storage and closet space, and a convenient half bath off the garage entry. The walkout lower level features a massive recreation room with incredible wood detailing, a 15-foot wet bar, and another stunning beamed ceiling, along with two additional bedrooms and a third full bath that was originally designed to serve as a steam room or sauna. Lovingly maintained and tastefully remodeled over the past decade, this remarkable 5,800-square-foot home sits on a beautiful half-acre lot with 145 feet of frontage on Big Spring Lake. Enjoy breathtaking lake views from many rooms, along with a cascading deck leading to the water, complete with a man-made waterfall and gazebo. Exceptional craftsmanship is showcased throughout with expansive open living spaces, floor-to-ceiling windows, abundant ceramic tile, extensive storage, and meticulous attention to detail. Conveniently located within walking distance of Grandville schools and parks, and just minutes from shopping, dining, expressways, and the lakeshore, this truly is a must-see property.
