5S440 Beau Bien Boulevard Rare gem near Steeple Chase and Steeple Run! First time on the market and a home that truly stands the test of time. Plus- this home is unincorporated with NO HOA but has the benefits of city water and sewage!This well-built and exceptionally maintained ranch offers over 2, 300 square feet above grade, delivering both comfort and flexibility from the moment you walk in. You can feel the care throughout, as this is a home that has been preserved, respected, and built to last. The family room features a vaulted ceiling with a striking wood beam and ceiling, creating a warm and inviting space to gather, while the generously sized kitchen offers ample room for everyday living and entertaining. Just off the main living area, the four seasons room provides the perfect setting for a home office, reading space, or playroom filled with natural light. One of the most unique features of this home is the expanded basement footprint which is larger than the main level as it extends beneath the garage. This space functions as a full secondary living area, complete with additional bedrooms, a full bathroom, kitchenette, living room, and its own private entrance! Ideal for guests, multi-generational living, or flexible use. While the home reflects its original character, it has been meticulously maintained, with systems and features that continue to perform exactly as they should. They simply don't build them like this anymore. What truly sets this property apart is the land opportunity. The property is currently undergoing a lot reconfiguration and includes an additional platted (not yet recorded) lot of 10, 000+ square feet. Once recorded, the future owner has the rare ability to either enjoy one of the largest lots in the neighborhood or separate and sell the additional lot for new construction, a unique opportunity in an area with virtually no available land. (Will leave to new owner to decide if they would like it recorded or not). Located within highly regarded District 203 schools, this property is also unincorporated while still connected to city water and sewer, offering added flexibility and long-term value in one of Naperville's most established locations. A rare combination of quality, space, and future potential. This is a property you don't see come around often.
