About This Property

Set on 2.6 acres with 308' of shoreline on Otter Lake, this architecturally striking retreat with its unforgettable setting offers an incredible sense of seclusion while remaining accessible year-round. From the moment you step inside, the cottage makes a definite impression. Soaring ceilings, walls of glass, polished concrete floors with in-floor heating on both levels, and dramatic design features create a space that is both bold and inviting. At the heart of it all is a magazine-worthy kitchen, outfitted with premium Thermador and SubZero appliances, sleek finishes, and a floor plan that keeps everyone connected. The cottage offers one primary bedroom with 3pc ensuite on the main level, while the upper level features a second primary suite with a 5pc ensuite and walk-in closet. Also on the upper level is a third guest bedroom plus a 3pc bath, and a bonus office or den overlooking the living area below. Outside, natural rock outcroppings, hardscaping, and a lakeside terrace with retractable screens create multiple places to relax and take in the surroundings. Evenings are best spent around the fire pit as you enjoy the summer sunsets. At the shoreline, the experience continues with a 2-slip boathouse featuring an upper-level living space overlooking the lake. Whether used as a quiet retreat, games room, lounge, or overflow space for guests, it offers spectacular views and a front-row seat to mornings on the water and star-filled Muskoka nights. Otter Lake is highly regarded for its exceptional water quality, with impressive depth, excellent nutrient levels, and remarkable water clarity, as indicated by a Secchi depth of approximately 5.9m, creating ideal conditions for swimming, boating, and enjoying the lake. Distinctive. Unexpected. Unforgettable. Otter Lake living, for those who appreciate great design, exceptional privacy, and a property with a personality all its own.
