Welcome to the Cummings-Wilson House, built in 1835 for a ship captain, a rare Federal-style antique in the heart of Cos Cob. This 4-bedroom, 4-bath home, including two en-suite baths, spans 3,492+ sqft on a 0.28-acre fenced, level lot. Preserved details include unadorned plaster walls and 9-foot ceilings throughout. A 2010 addition matches the original architecture seamlessly, while a comprehensive 2022 renovation added modern systems, insulation, storm windows, and integrated A/C. Set in the sought-after Cos Cob Elementary zone, it is walkable to the train station, marinas, shops, and schools, with Metro-North and the Sound just steps away. A genuine landmark antique, rarely available.
