Welcome to 142 Mill St., a stunning luxury estate set on approximately 2 acres along the Sauble River. A grand circular concrete drive leads to this serene property where timeless elegance meets modern comfort. The post & beam covered wraparound porch and gazebo create the perfect setting for morning coffee or peaceful evenings, showcasing beautiful river views and seamless indoor-outdoor living. Watch for otter, beaver and muskrat as well as bald eagle, egret and blue heron, fox and turtles along your private shoreline. Inside, a dramatic two-storey foyer with limestone flooring opens to a bright living room with floor-to-ceiling windows reaching to the 23' post and beam cathedral ceiling, rich cherry hardwood, and a striking stone gas fireplace. The gourmet cherry kitchen features granite countertops and sinks, a centre island, built-in appliances, and a breakfast credenza, plus a multi-tiered deck ideal for entertaining against the river backdrop. A formal dining room is perfect for gatherings, while a private main-floor office enjoys inspiring water views. The oversized triple-car garage with in-floor radiant heat (a mechanic's dream) connects to a spacious mudroom. Upstairs, the primary suite offers a sitting area and spa-inspired ensuite with a freestanding tub overlooking the river, glass-and-tile shower, double vanities, and private water closet. Two additional bedrooms with double closets share a full bath, plus second-floor laundry. A third-level bonus room offers many options! The Lower level is an entertainer's dream with a large family room, dry bar, media room, infrared sauna, 5th bedroom, cold room and walk-out to the stamped concrete patio. The property extends across the river with water rights. The 4,000 sq.ft. detached "Bee House" includes a workshop heated with natural gas, playroom, and plenty of flexible storage. A welcoming community, ideally located between Owen Sound, the Lake Huron shoreline, and Bruce Power in the middle of everywhere!
