Description

Built in 1883 at the height of America’s Gilded Age, Comfort Island is one of the Thousand Islands’ most distinguished private estates. Commissioned by a prominent Chicago industrialist during the era when America’s great fortunes created legendary summer residences along the St. Lawrence River, the estate represents a rare opportunity to own not simply a home, but an enduring piece of North American history. Occupying approximately 1.8 private acres , 9 bedrooms, 4.5 baths, the island has been painstakingly transformed through an extraordinary eight-year restoration. Every surface was carefully renewed while preserving the craftsmanship and character that define the estate’s nineteenth-century origins. Behind its historic walls lies an entirely modern residence, featuring new plumbing, electrical systems, HVAC, insulation, and mechanical infrastructure, allowing today’s owners to enjoy the elegance of the Gilded Age with every contemporary convenience. Surrounded by the sparkling waters of the St. Lawrence River, the estate feels worlds away, yet the mainland marina is only three minutes away by boat, placing restaurants, boutiques, golf, marinas, and everyday conveniences within effortless reach. The estate extends well beyond the main residence. A collection of beautifully restored historic outbuildings creates intimate destinations throughout the property—spaces for entertaining family and friends, quiet reflection, creative pursuits, or simply enjoying the rhythm of river life. Expansive dockage and a classic boathouse provide exceptional accommodations for both residents and visiting guests, making arrivals by water as gracious as they were more than a century ago. Whether hosting an elegant summer dinner on the porch, gathering generations of family for celebrations, or enjoying a peaceful morning overlooking passing yachts and freighters, every corner of the property has been designed to embrace both grand entertaining and private retreat. This is truly a rare offering.
