Welcome to your off-grid paradise on the north side of Reed's Bay - where "rush hour" means the herons are fishing. This 17 year old 3-bedroom, 1-bathroom home/cottage delivers bright, open-concept living with a wall of windows framing the water like a living painting. Morning light floods the space as the sun climbs over the bay, and by evening you're sinking into the deck chairs watching pinks and golds melt across the sky - because here, you're not just buying waterfront, you're buying a front-row seat to nature's daily light show. Propane heat and a wood stove let you pick your vibe: turn a dial or channel your inner lumberjack while the kettle boils. The solar system works so well you'll forget you're off-grid - all the power to run the home, none of the hydro bills. Flip a switch, plug in anything, live normally. Just without the monthly envelope from the utility company. Neighbours? Technically yes. Practically? They're specks across the fields. Wave if you want. They won't see you. Outside, the property unfolds with room to breathe and space to play on 3+ acres. An 8' x 12' garden shed holds your garden tools, while a 12' x 24' workshop/bunkie features a separation wall - one side for building projects and tinkering, the other for overnight guests or the growing fleet of watercraft you'll inevitably collect. Down at the water's edge, a dock and boat lift make launching effortless. The fire pit invites late-night storytelling under impossibly starry skies, and the wrap-around deck gives you more summer living space than you'll know what to do with. This is the cottage you actually use peaceful enough to hear yourself think, equipped as well as your home, and charming enough to make your friends promise to exchange chores for a few nights at your place. Many furnishings included with the purchase plus detailed instructions about the solar system. Boat lift included (2000 lbs). https://youtu.be/SxpSU_THIb8?si=EF8IRY87CnsnjSoq
