Two homes. One waterfront. Zero compromises. Most lake properties force a choice: do you bring family, or do you finally get the quiet you came for? This rare Clayton Lake home lets you do both. Two fully self-contained units under one roof, each with its own kitchen, bathrooms, bedrooms, furnace, and electrical panel. Real independence, not a shared hallway with a closed door. The lower walk-out level offers two bedrooms, an office/bedroom, and a three-season sunroom where the lake becomes part of the everyday view. Radiant in-floor heat keeps winter mornings warm underfoot. Upstairs, four more bedrooms, a four-season sunroom built for year-round use, and a private balcony positioned for watching the sunset reflecting off the water. Seven bedrooms and five bathrooms total. Enough room for the whole family, and enough separation that everyone still likes each other on Monday morning. Outside, Clayton Lake delivers what buyers keep asking for and rarely find: a clean shoreline with minimal weeds, your own dock and boat launch, and a short walk to the Clayton general store and parks. Year-round road access. Snowmobile trails close by for the winter months. This is a family compound built for generations. Bring aging family members close while preserving everyone's independence. Help an adult child step into ownership without sacrificing your own space. Or hold it as the gathering place every summer for the next thirty years. Waterfront properties with two complete living spaces appear once in a decade. The families who find them tend not to let go. Book your private showing before another family does.
