Most waterfront buyers search for a cottage. This is something rarer: a private island compound in The Archipelago, surrounded by Georgian Bay and built for family, guests, and legacy ownership.
Set on 5.8 acres with 846 feet of shoreline, 20 Harrison Island includes a substantial main residence, a self-contained A-frame guest house, extensive docking, sandy beach frontage, year-round systems, and over 8,000 square feet of finished living space.
With more than $4 million invested into construction, infrastructure, and materials, this is not a seasonal cottage dressed up as an estate. It is a true private island retreat designed for permanence.

Walk every room, floor by floor, in the full interactive tour — the complete compound, rendered in immersive 3D detail.
Begin the WalkthroughMain residence — three floors. Guest house — two floors. Click any plan to view full size.
The main residence is designed for gathering — generous living spaces, a chef's kitchen, water-facing principal rooms, a dining room for 16, and expansive decks that keep Georgian Bay in view from morning to night. A screened outdoor kitchen pavilion, a recreation room, and three full baths plus a powder round out the main floor and upper levels.
The A-frame guest house gives visitors their own complete retreat, with four bedrooms, private ensuites, a full kitchen, cathedral ceilings, and a wall of glass facing the bay. A powder room, marble showers, and a loft bunk room under the eaves round it out — guests live with the same privacy as the principal home, and the guest house has a proven short-term rental history.
An interior kitchen with gas pendants and full sightlines to the bay. A second, screened outdoor kitchen pavilion with stone feature wall and bar seating for shoulder-season entertaining.
Hot tub · billiards room with water views · life-size outdoor chess · dive tower at the water's edge · beach volleyball court · observation deck · heated workshop · expansive deck systems. Designed for many bodies and many summers.
Winterized · generator-wired · 200 AMP · drilled well with reverse osmosis · septic. The island lives through every season.
Two distinct shorelines. Soft sand for the family, rugged shoreline for the views. Northern lights over the bay on a clear autumn night.
Total construction cost exceeded four million dollars. Materials and systems chosen for generational permanence — not seasonal use.
With 846 feet of private Georgian Bay shoreline, the island offers multiple ways to experience the water — deep-water docking, a sandy beach, rocky lookout points, and open views across The Archipelago.
Arrive by boat, stay for the privacy, and own a piece of Georgian Bay that simply cannot be recreated.
For qualified buyers seeking a rare Georgian Bay compound, private tours can be arranged with advance notice.
