Welcome to an unparalleled Georgian Bay retreat--an exclusive 18+ acre estate on the highly coveted Mowat Island, just 10 minutes by boat from Hwy 400 & two local marinas (Harrison Landing & Carling Bay). Offering exceptional privacy, this legacy island property features 1,575' of pristine shoreline, where smooth granite outcrops meet a natural 400' sandy beach & sheltered lagoon with shallow, child-friendly entry. Crafted by Spragge & Company Architects & constructed by renowned builder Ron Bowman, the main cottage is a timeless blend of classic cottage warmth & refined design, seamlessly integrating indoor & outdoor living. Vaulted pine ceilings with dormers, slate floors & a dramatic floor-to-ceiling cultured stone fireplace set the tone for relaxed elegance. An inviting sunroom bathed in natural light offers water & forest views, while the custom kitchen boasts abundant cabinetry & premium finishes. The principal bedroom features a walkout to the deck & a second-level loft provides a cozy retreat for children or guests. Expansive panoramic southeast views of Parry Sound are matched only by the private west facing point, ideal for unforgettable sunset gatherings. With two deep-water docks, the shoreline accommodates larger vessels, making arrival & exploration effortless. A charming guest bunkie sits just steps from the beach, complete with kitchen amenities, a 2-pc bath & a secluded outdoor shower perfect for hosting family or friends in comfort & style. Wander the picturesque walking trails that wind through the property's mature forest, discover foraging delights, or relax at the tent platform perched on an elevated rock face, where sweeping views create a tranquil escape. Zoning allows for a second full cottage on the property, and the existing Managed Forest Tax Incentive Plan (MFTIP) offers notable tax savings. Turn-key and fully furnished, this one-of-a-kind island estate is ready for immediate enjoyment.
