Tucked into a Group of Seven-inspired landscape of windswept pines and smooth granite, this modern Lake Rosseau Estate of approx 5500 sq' of chic interior living captures the timeless sophisticated beauty of Muskoka. Set on 5.8 private acres with 485 feet of pristine frontage(assessed), the property offers a rare combination of seclusion, elegance, and natural drama. At the heart of the Estate stands a contemporary four seasons cottage, where warm wood tones and expansive glass create a seamless connection between indoors and out. Designed for both grand entertaining and quiet lakeside living, the main cottage features bright and grand living spaces, a floor-to-ceiling stone fireplace, large principal rooms, five luxurious bathrooms, and a lower-level walkout that opens to perfectly landscaped perennial gardens overlooking the lake. Off the Muskoka room and kitchen, a granite terrace with a barbecue and outdoor dining area is set among mature pines and perennial gardens- a serene and private setting for alfresco meals and evening gatherings. The water's edge natural stone fire patio area-perfect gathering place to end the day. Complementing the Principal Lakehouse are several exceptional outbuildings that extend the lifestyle experience. A two-bedroom boathouse with full facilities, a lounge, and three boat slips, offering guests a front-row connection to the water. A yoga pavilion, perfectly placed for sunrise practice and relaxation. A dedicated office/studio with its own washroom-ideal for remote work or creative pursuits. A private tennis court set back among the trees, combining recreation and Muskoka charm. An infinity pool near the pavilion and court area, offering tranquil views across the forest canopy. Every detail of this property has been thoughtfully composed to balance modern design with Muskoka's natural artistry-a true lakeside retreat where architectural sophistication meets the wilderness.
