Located in the heart of downtown St. Augustine’s Historic District, 345 Charlotte Street offers the rare combination of historic character and modern construction. Built in 2004 and constructed of concrete block, this home reflects the architectural charm of its surroundings while providing the layout, efficiency, and durability today’s buyers expect—fantastically insulated and solidly built, offering a quiet, fortress-like feel rarely found downtown. A paver walkway leads to an arched front porch with brick columns and subtle LED string lighting, framed by mature landscaping, climbing jasmine, and garden latticework that creates a private and welcoming entrance. Inside, the home features a warm yet refined atmosphere with a classic fireplace anchoring the living room with custom built-in bookshelves on either said, plantation shutters throughout, and an efficient kitchen with new range and microwave. French doors open to a secluded garden patio surrounded by lush greenery, offering a peaceful outdoor retreat. The primary bedroom and second bedroom both include private balcony access, adding to the home’s sense of space and privacy. This 3-bedroom, 2.5-bath residence is offered furnished, with thoughtfully selected pieces that complement the home’s architectural style. Closet systems have been updated within the last three years, improving functionality while preserving the home’s character. Zoned HP-2 (Historic Preservation), short-term rentals are not permitted; however, rentals of 30 days or longer are allowed, making the property well-suited for full-time living or extended stays. An exceptional feature for downtown is the availability of five off-street parking spaces. Set on one of the most peaceful streets downtown, with a short walk to a nearby park, yet just steps from renowned dining, historic landmarks, and the cultural heartbeat of St. Augustine, this property presents a truly rare opportunity to own a modern, solidly built home in one of the city’s most sought-after historic locations.
