About this home

NOT YOUR TYPICAL BAYVILLE HOME. Tucked away on an intimate dead-end street shared by just four homes, 3 Finnin Place is a distinctive carriage house offering character, privacy, incredible versatility, and the relaxed coastal lifestyle that makes Bayville so special. Inside the home immediately feels different. Dramatic vaulted ceilings, exposed beams, and a wood-burning fireplace create a warm, open atmosphere, while the flowing living, dining, and (updated) kitchen spaces make entertaining effortless. The updated primary suite features a private en-suite bath, with two additional bedrooms and flexible spaces that allow the home to adapt to the way you live. And then there’s the garage. Far more than ordinary garage space, the oversized, fully heated garage features approximately 12-foot ceilings, oversized doors, 220V electrical capability, generous clearance, and potential for a vehicle lift, subject to proper installation and applicable requirements. It’s an incredible find for the car collector or enthusiast—but equally appealing for anyone craving serious space for a workshop, studio, equipment, hobbies, storage, or simply a garage unlike almost anything else on the market. Outside your door, enjoy everything that makes Bayville one of Long Island’s special North Shore communities—beaches, boating, waterfront recreation, parks, restaurants, shops, and the unmistakable charm of coastal living. 3 Finnin Place isn’t a cookie-cutter house—and that’s precisely the point. It’s a home for the buyer looking for something with character, something with possibilities, and something they won’t find everywhere else. Come experience it in person. This one deserves a closer look.
