Property Description
Welcome home to this beautifully renovated Colonial, privately set on 1.87 landscaped acres at the end of a picturesque cul-de-sac in Armonk. 12 Lyons offers a wonderful blend of classic character, modern updates, sun splashed spaces, and a flexible floor plan designed to adapt to the way you live. The living room is warm and inviting, with gleaming hardwood floors and a handsome wood-burning fireplace, the perfect place to gather on cozy evenings. The adjoining dining room boasts a bay window, the eat-in kitchen is spacious and boasts ample cabinetry, and a fabulous sunroom off the living room is wrapped in windows to bring the outdoors in, a peaceful spot for morning coffee, reading, or simply enjoying the changing seasons. A flexible use private office/playroom/guest room and convenient powder room complete this level. Upstairs, the comfortable primary suite includes a large ensuite bathroom with a skylight, double sinks, and soaking tub, and three additional bedrooms and a full bathroom on this level provide space for all. Outside, the property truly comes to life. Two decks and a spacious patio create inviting places for outdoor dining, entertaining, gardening, play, or simply unwinding at the end of the day. The expansive grounds provide plenty of room for pets and recreation while offering a wonderful sense of privacy and connection to nature. An exceptional place to call home.
