About this home

Welcome to 18 Bonaventure Avenue, a rare opportunity in the heart of the Village of Ardsley with Ardsley Schools. Built in 1970 and offered for the first time since its original ownership, this solidly built home is ready for its next chapter. Offering four full levels of space, the home features a bright and spacious 3 bedroom, 3 full bathroom duplex highlighted by dramatic cathedral ceilings, skylights and an abundance of natural light. Generously sized living and dining areas provide plenty of room for everyday living and entertaining, while multiple balconies extend the living space outdoors. Adding even more potential is a full unfinished basement and sub basement with walkout access from each level, which is not included in the stated square footage and provides tremendous possibilities for storage, recreation or future use. An attached garage, multiple outdoor spaces and a versatile layout further enhance this unique property. Conveniently located near Ardsley Village shops, restaurants, parks, schools and major roadways, with easy access to nearby Metro North stations. A tremendous opportunity to customize a substantial home in one of Westchester's most desirable communities and make it your own.
