Property Description
Welcome to life on one of the coolest cul-de-sacs in Treaty Oaks -- where neighbors gather, block parties happen, and community feels effortless. Tucked away on a quiet street and backing directly to a peaceful preserve, this home offers a rare combination of privacy, space, and connection in the only St. Augustine community that offers a private entrance directly into all the incredible amenities of Treaty Park. Built in 2019, this thoughtfully designed 5-bedroom + office/flex room, 3.5-bath home offers a layout that truly works for the way people live today. The main level is both functional and inviting, featuring a versatile flex room at the front of the home - currently offered as an office but is also a conforming sixth bedroom or guest space if needed. A separate formal dining room provides the perfect setting for hosting holidays and special gatherings, while still maintaining a sense of privacy from the main living areas.
