About this home

Welcome to one of the most spectacular estate style waterfront properties in the heart of the 1000 Islands on the St Lawrence River! Situated on a 1.2-acre lot in the prestigious St. Lawrence Park community, this remarkable estate combines timeless Gilded Age charm with a full modern, high-end restoration. Every inch has been thoughtfully improved for a true turnkey experience, with exquisite attention to detail. The main residence offers 5 bedrooms and 3.5 bathrooms, all with majestic premium hardwood floors. The kitchen showcases Thermador appliances, brass finishes, and granite countertops. All new electrical and plumbing! The attic space has been fully finished and all of the windows in the house are brand new. Premium central air in every room for year-round comfort. Each of the 3 full bathrooms are enhanced with luxurious finishes sure to impress. Square footage on the listing is reflective of recent floor plans. Step outside to unobstructed views of the American Narrows where freighters glide past as if in your own front yard. The nearly 1, 000 sq. ft. covered porch provides a front-row seat to the river’s beauty, while the outdoor living spaces rival those of a luxury resort. A massive seal-coated parking area—large enough for nearly 30 vehicles, a rare find for waterfront property—connects to premium hardscaping, perennial gardens, and an expansive stamped concrete patio. The grounds are landscaped for both beauty and function, with a thoughtful mix of shade trees and open sunny areas. Water access is exceptional with a modern deep-water dock and the original boathouse—an iconic feature of the 1000 Islands—now a fully finished 2-bedroom, 1-bath guest residence perched over the water. Guests can wake to the sound of waves beneath them and step outside to the dock in seconds, making for an unforgettable riverfront experience. Steeped in history as one of St. Lawrence Park’s earliest residences, this estate has been reborn through a premium, no-expense-spared restoration. It’s a perfect blend of historic charm and modern luxury, offering maintenance-free enjoyment of one of the most beautiful waterways in the world.
