Beneath a sweeping canopy of mature oaks, this well maintained home offers a private garden retreat on nearly half an acre spanning five platted lots in St. Augustine South. Positioned on a spacious corner at Shamrock Road and Shore Drive, with coastal marsh just across Shore Drive and generous separation from neighboring homes, this concrete block home combines exceptional privacy with a peaceful natural setting, thoughtful updates, and room to enjoy the outdoors. Lovingly cultivated by a dedicated gardening enthusiast, the grounds feature winding garden paths, diverse plantings, beautiful flowers, fruit-bearing plants, and vegetable-growing areas. Explore your own backyard landscape, relax beneath the oaks, or imagine adding a pool with space to spare. Inside, fresh paint, hardwood floors, a fully updated kitchen with over-sized granite top island, and remodeled bathrooms create a warm, welcoming feel.
The covered, screened lanai opens onto a deck with a pergola, creating an inviting outdoor retreat for morning coffee or a relaxing evening overlooking the gardens. A large two-car garage and large shed provide ample space for storage, tools, and hobbies. A 2023 roof, 2026 AC unit, and newer water heater add practical value, while a well water system serves the property. Situated in Flood Zone X. No HOA and the potential for vacation rental use offer added flexibility. The nearby public boat ramp makes getting out on the water convenient, while scenic Shore Drive is right outside your door for morning walks along the marsh. Enjoy St. Augustine South’s waterfront parks, public boat ramps, boardwalk, walking areas, and picnic spots, along with convenient access to shopping, dining, historic downtown St. Augustine, and the beaches. An exceptional opportunity to enjoy garden-filled grounds, coastal surroundings, and space to make your own.
