1816 Battery Island Drive

A rare opportunity to own a fully livable coastal cottage with the flexibility to build a larger primary residence in front--just 3 miles from Folly Beach. Tucked toward the back of this .40-acre lot, the existing 729 sq ft home (classified as an ADU) offers immediate use as a primary residence, guest cottage, or income-producing rental. The current home features wood-look tile flooring, updated windows, a tankless water heater, mini-split HVAC, and a roof replaced by the previous owner. The front porch/deck was replaced in November 2025, adding to the home's charm and functionality. Enjoy marsh views across the street, along with steady ocean breezes and salty air in a location that feels relaxed yet incredibly convenient to shopping, dining, and downtown Charleston.The property is......zoned to allow construction of a main residence up to approximately 2,700 sq ft in front of the existing cottage, offering multiple paths forward. One proposed option is the Kennedy floor plan by Hunter Quinn Homes, a raised coastal design with a drive-under garage, ideal for beach and Lowcountry living with ample storage for vehicles, golf carts, and outdoor gear. The plan includes a welcoming foyer, a study or flex space off the entry, and a spacious primary suite with a large walk-in closet and well-appointed bath with a separate water closet. Live in the existing home while planning or buildingor keep the property as-is for a simpler life. Few properties offer this level of flexibility, location, and income potential in such close proximity to Folly Beach.
