GORGEOUS MID-CENTURY MODERN RETREAT WITH 112 FEET OF FRONTAGE ON THE MAIN CHANNEL OF THE ST. LAWRENCE RIVER! Nestled amongst the towering pines of Round Island, the 'Windsong' cottage is a rare mid-century modern retreat offering 114 feet of pristine frontage on the main channel of the St. Lawrence River. This untouched architectural gem is a dream for design enthusiasts, with its original mid-century details beautifully preserved. A signature wall of windows, true to the era, invites in soft river breezes and frames panoramic water views, while the expansive deck offers a front-row seat to breathtaking sunsets and world-class ship watching. Here, the serenity of island life blends effortlessly with convenience — just a short boat ride from the renowned shopping, dining, and waterfront charm of Clayton. Thoughtfully balancing retro character with modern practicality, Windsong is equipped with satellite and internet capability, making it ideal for extended stays or remote escapes. Adding to the opportunity, the current owner — who also owns the neighboring cottage — is offering the buyer one year of access to their boathouse dock slip and septic system, providing valuable time to install private systems. Recent estimates place dock installation between $72,000–$100,000 and septic installation between $27,000–$30,000. Please note: current taxes and assessment reflect both properties and will be adjusted upon sale. This is more than a cottage — it’s an iconic piece of Thousand Islands history in an unbeatable main-channel setting. Call or text today to schedule your private tour of Windsong.
