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. At the heart of the home, the open-concept kitchen and living space come together beautifully--designed for connection, comfort, and everyday moments. The kitchen features a large center island, farmhouse sink, and plenty of room to gather, all flowing seamlessly into the living room where a cozy fireplace creates a warm and welcoming focal point. Sliding doors lead directly out to the expansive screened lanai, extending your living space outdoors and making it easy to enjoy everything from quiet mornings to lively evenings with friends and family.
The primary suite is conveniently located on the first floor, creating a private retreat with a free-standing soaking tub, walk-in shower, large walk-in closet, and a spacious, comfortable layout overlooking the private backyard.
Upstairs, you'll find four additional bedrooms and two full bathrooms, including a bedroom with a private en-suite bath, offering flexibility for guests and literally built for multi-generational living.
Step outside to your expansive screened lanai (approx. 40' x 10')--an ideal extension of your living space. Already equipped with a TV mount, it's the perfect setting for morning coffee, evening wind-downs, or weekend gatherings while enjoying uninterrupted preserve views. The fully fenced backyard adds both function, privacy, and peace of mind.
Beyond the home, Treaty Oaks offers a lifestyle that's hard to beat, with access to community amenities including a pool, fitness center, playground, and a private gated entrance into Treaty Park, where walking/running trails, pickleball courts, a dog park, skate park, and outdoor recreation are just moments away.
With a 2-car garage, easy access to I-95, and a short drive to the beaches and historic downtown St. Augustine, this home brings together location, lifestyle, and livability. This truly is not one to miss - this is the lifestyle upgrade you deserve. Schedule your showing today!
