Stunning southeasterly views across Lake Rosseau. This exceptional waterfront property offers breathtaking, wide-open lake views from almost every room and features a beautifully refreshed 4-bedroom, 3-bathroom cottage with a separate coach house. Recently updated with fresh interior and exterior paint on the cottage, coach house, and boathouse, the property also includes a new furnace, new heat pump, new alarm system, and a beautifully updated upstairs bathroom. The 3,121 sq ft cottage has been thoughtfully designed to maximize the spectacular lake views, with nearly every room overlooking the water. The open-concept main living area features vaulted ceilings, an abundance of natural light, and a cozy stone fireplace. Just beyond is the dining room with walkout to a balcony and a spacious great room anchored by a second impressive fireplace. The main-floor primary bedroom includes a 4-piece ensuite and walkout to the Muskoka Room. Upstairs are three additional bedrooms, a renovated 4-piece bathroom, and a loft overlooking the main living area, ideal for a home office or reading nook. Above the attached 2-car garage, the 562 sq ft coach house provides comfortable guest accommodations with its own bedroom, bathroom, and private balcony, offering excellent privacy for family and friends. At the shoreline, the boathouse is equally impressive, featuring three slips with two boat lifts inside, plus two Sea-Doo lifts outside. The covered lakeside seating area is designed for comfort throughout the season, complete with retractable screens for wind and bug protection and a gas fireplace, creating the perfect space to relax and entertain while enjoying the stunning Lake Rosseau views.
