Own the entire block! At 9 Mansfield Avenue, you don't just buy a home; you acquire a unique 0.7-acre 'island' parcel with zero shared property lines. This is a self-contained sanctuary in the heart of the Marstons Mills Lake District, a place where the landscape belongs entirely to you. Bounded only by quiet village ways, the grounds are a lush perimeter of mature maples, hydrangeas, vibrant azaleas and rhododendrons. Inside, the home is spacious and inviting, with room for all to stretch out and relax. The kitchen, with maple cabinets, granite counters, and tumbled marble backsplash, features sliders that open directly onto a sweeping, semicircular mahogany deck. From this elevated lookout, you can survey your property and the shimmering waters of Shubael Pond across the way. A classic Dutch door connects the kitchen to a light-filled, enclosed breezeway--the perfect transition space that opens onto a lower grilling patio and leads through to the oversized one-car garage, complete with a dedicated cedar closet. The layout offers the ease of first-floor living, featuring a primary bedroom, a full bath, a den, and a living room centered on a wood-burning fireplace. Upstairs, three additional bedrooms and a second full bath complete the home. Complemented by a brand-new four-bedroom septic system, this property is as practical as it is distinctive. It stands as a private retreat within a cherished community, an oasis surrounded by the kettle ponds, bogs, and trails of the Mills. Exactly one mile from the Olde Barnstable Fairgrounds Golf Course, and moments from dining, shopping, and Route 6.
