In the heart of Fullerwood, one of Uptown St. Augustine's most established and character-rich neighborhoods, you'll find an exceptional blend of charm and modern sophistication at 39 E Park Avenue. This top-to-bottom renovated pool home features 3 bedrooms, 4 full baths, and 1 half bath across more than 2,500 square feet of living space, perfectly situated less than two miles from Historic Downtown St. Augustine and just minutes from the beaches of Vilano. Raised in 2025 and removed from the flood plain, the home's architectural integrity and thoughtful renovation deliver the best of both worlds: classic charm and modern security. Originally built decades ago, the property underwent a major renovation in 2022 and was elevated and completed with an all-new main level build in 2026. Step inside the newly constructed first floor to an inviting living area with tiled floors throughout, complemented by sliding glass doors that open to the lanai and outdoor living space. Here, you'll find a brand-new gas-heated pool and spa, a cozy firepit with a seating area, and a fully equipped summer kitchen, ideal for entertaining or relaxing year-round. This level also features a beautiful ensuite bedroom and a half bath for guests. Upstairs, refinished oak hardwood floors set the tone for the home's open and sun-filled main living space. The renovated kitchen (2022) impresses with custom cabinetry, Caf appliance package including a wine cooler and double oven, elegant wood countertops, and a tiled backsplash. The upper level also hosts two owner's suites, each offering beautifully updated en suite baths with designer tile showers and updated fixtures. From the upstairs bedroom, step onto the large balcony to enjoy protected views and a peek at the water. Every system in this home reflects careful attention to detail and quality, including an all-new electrical panel and wiring (2025), updated plumbing, new HVAC ductwork, and roof upgrades (main roof 2022, balcony and rear metal roof 2026). Outside, a covered sitting area with an outdoor shower adds yet another touch of convenience and coastal lifestyle appeal. Fullerwood's location is unbeatable; tree-lined streets, architectural variety, and water access make it one of St. Augustine's most desirable enclaves. A neighborhood kayak launch is just down the street, offering easy access to the Intracoastal, while the vibrant Downtown Historic District is less than a five-minute drive for dining, shopping, and cultural experiences. Whether you're looking for a primary residence, a vacation home, or an income-producing short-term rental (one-week minimum permitted), this property delivers rare flexibility, enduring value, and timeless charm in one of the most coveted areas of St. Augustine.
