About this home

There is a distinct magic to a classic cottage that modern builds just can't replicate. It's found in the gentle creak of the floorboards, the way the afternoon sun streams through the windows, and the immediate peace that washes over you the moment you pull into the driveway. 339 Sunnylea Ave is exactly that kind of place-a timeless waterfront retreat featuring a spacious four-bedroom layout that has spent decades hosting laughter, summer barbecues, and quiet morning coffees. Bound by a picturesque, winding creek on a level lot, this property feels less like a standard piece of real estate and more like your own private sanctuary.For years, life here has revolved around the water. The day begins with a cup of coffee on the dock, watching the mist rise off the lake while casting a line into the glassy water. As the afternoon heats up, the rare, level sandy beach becomes the focal point for family fun-whether that means building sandcastles with the kids, launching a kayak into the lake, or simply wading into the cool, clear water. It is the kind of effortless waterfront living where you don't have to trek down steep stairs or navigate difficult terrain; the lake is quite literally at your doorstep. Inside, the four bedrooms offer ample space for family and weekend guests, making it an ideal haven for creating lifelong memories together.While the cottage itself is older and gently showing its age, it is absolutely brimming with character and possesses a soul with plenty of life left to give. It stands as a beautiful canvas awaiting its next chapter. You can comfortably enjoy it exactly as it is for rustic weekend escapes this summer, or you can bring your design ideas and a toolbelt to breathe modern life into its classic footprint. Whether you choose to lovingly restore its vintage charm or renovate it into a contemporary lakeside masterpiece, 339 Sunnylea Ave offers a rare foundation to build the ultimate family legacy.
