There's a house on Greenland Circle that doesn't quite know it's on Cape Cod - or maybe it knows exactly what it is and refuses to apologize for it. From the road, it plays along with its neighbors: navy shingles, white trim, a rambling roofline tucked into the oaks and pines, among the kind of sophisticated, well-kept homes that don't usually go in for surprises.Open the front door and that composure loosens, just a little, in the best way - a glass bubble chandelier greets you first, playful and elegant at once, nothing you'd expect from a house this size in a neighborhood this refined. Behind it: one long, unbroken run of space. Kitchen drifts into dining, dining opens into a great room that just keeps going, all of it floored in hardwood that holds the afternoon sun.Almost 3,000 square feet, and not one wall tells you where the living room ends and the dining room begins. Vaulted ceilings lift the whole space up and away, and the effect is almost meditative - quiet in its palette, spare in its furnishings, enormous and still somehow cozy. This isn't a house for a formal dining room and a den. It's for the buyer who wants eclectic over traditional, who'd rather have one great room than four small ones with doors.The sunroom off the back is its own quiet world - walls of windows, a vaulted ceiling with an exposed beam, and a view over a terraced stone wall and garden. And yet, for all that calm, this is a house built to fill up: a path across the street cuts straight into Dennis Pines, Cold Storage Beach and Sesuit Harbor are both minutes away, and the open layout means the whole day's company lands in one room at once.The lower level adds real living space with a garage that feeds right in - a fourth bedroom, a family room, and a flex room ready to be a craft room, office, home gym, or bunk room. Outside, a new composite deck with a built-in gas grill overlooks the terraced garden, steps down to a patio built for evenings when everyone's finally home.A hard house to describe - quiet and full at once. You really have to stand in that great room to feel it.
