Wake up to the water every morning at 3 Koehn Road on Grand Lake St. Marys, where lakefront living meets thoughtful craftsmanship and everyday comfort. Built in 2009 and beautifully maintained, this 3,516 sq ft home sits on a rare 0.65-acre lot and offers sweeping lake views from nearly every room.
The heart of the home is the bright, open great room with custom hardwood floors and a stunning copper-surrounded fireplace, perfectly positioned to frame the lake beyond. Just off the main living space, the newly enclosed Florida room with floor-to-ceiling windows creates the perfect spot for morning coffee, sunset views, or hosting friends year-round.
The kitchen was designed for both cooking and gathering, featuring granite countertops, quarter-sawn oak cabinetry, a six-burner cooktop, hidden stainless vent hood, and newer appliances. A formal dining space, cozy office nook, and a practical laundry room complete the main level.
The main-floor primary suite feels like a private retreat with expansive walk-in closets, dual vanities, a soaking tub, and spa-style walk-in shower. Upstairs, a second primary suite and additional bedrooms all feature walk-in closets and ceiling fans, offering space and comfort for family or guests.
Outside, lake life takes center stage with a boathouse, built-in barbecue area, and generous entertaining space designed for summer evenings by the water.
The extra-deep 3+ car garage, whole-home generator, dual HVAC systems, central vacuum, lake-fed irrigation, and quality construction details throughout reflect the care and craftsmanship poured into this home.
If you've been dreaming of space, privacy, and unforgettable lake views on Grand Lake St. Marys, this is the kind of home that rarely becomes available.
