Welcome to this extraordinary 4-bedroom custom built home by Park Avenue Homes, backing onto a private ravine. Spanning 4,991 sq. ft. with a three-car garage, this home features 10-foot ceilings on the main floor, 9-foot ceilings on the second floor and basement, and a soaring 20-foot ceiling in the dining room. 11-inch wide-plank White Oak (2025) hardwood flows throughout the main and second floors, complemented by wainscotting and plaster crown moulding throughout. The gourmet kitchen features quartzite countertops, a walk-in pantry, and a butler's pantry with a built-in wine fridge. Appliances include a 36" Wolf gas range, Wolf built-in oven and microwave, Vent-A-Hood range hood, and Bosch dishwasher. Upstairs offers four bedrooms with private en suites, including a primary suite with its own fireplace, custom closets, and a luxurious ensuite finished in marble flooring and marble countertops. Custom cabinetry has been thoughtfully built into the laundry room, upper hallway, and most closets throughout the home. The walkout basement includes a family room, games room, theatre, second wine fridge, and two additional rooms that can be used as an office or a gym. Vinyl flooring runs throughout, with a three-piece bathroom featuring a fully equipped steam shower with glass enclosure and bench. Enjoy a private ravine-view retreat: a fibreglass saltwater pool with attached saltwater hot tub, a second hot tub built into the deck, perfect for the cooler months, a custom stone fire pit, and a backyard pavilion custom built by Wolf Lakes Timber Works (2025). The main-floor walkout leads to the deck, equipped with a natural gas BBQ and fireplace, and completely refaced in 2026 with Zuri PVC decking. Irrigation services the front and backyard gardens. Homes of this caliber - combining custom craftsmanship, a private ravine setting and resort-style outdoor living - seldom come to market. An outstanding opportunity to own one of Durham Region's most distinctive properties.
