Room for everyone on the St. Lawrence River! If you’ve been searching for a year-round Thousand Islands waterfront home with space for the whole crew plus guests, this is it. The revamped ranch has 4 bedrooms plus a private in-law suite, four and a half bathrooms, a stunning kitchen, two living rooms, and a sunroom with patio doors that open onto the deck. From here you’ll hear the freighters’ salutes as they glide through the shipping channel. Downstairs, the 2,740 sq ft finished walkout basement adds two additional bunk rooms, so you’ll have extra sleeping space for kids, grandkids, and guests. There’s also plenty of room for games, movies, and hobbies. Step out the lower-level patio doors to a second outdoor entertaining area, then take in the views across your 1 acre to your private dock. The oversized garage holds the boat, the vehicles, and all the toys at the same time. A home like this rarely comes along!
