Description
Some of the most impressive features of this 2024 built Grassy Key residence are the ones you may never notice. From its ICF construction and steel framing to the underground utilities and carefully engineered grounds, 58244 Overseas Highway reflects a level of planning that goes well beyond the ordinary. Four-foot-deep underground walls on three sides help protect against erosion, while geogrid beneath the gravel driveway adds stability. Oversized 1'' water piping, impact-resistant windows and doors, a metal roof and extra clearance underneath for RVs and boats with T-tops further demonstrate the attention to detail. The same thoughtful approach carries inside, where an expansive open living area captures spectacular Atlantic Ocean views and offers generous room for entertaining. An oversized oceanfront primary suite features balcony access, a spacious bathroom and walk-in closets. Three additional bedrooms, two full guest baths, laundry, utility room and a large pantry complete the floor plan. Outside, the property's true appeal becomes clear. A beautiful oceanfront pool and private sandy beach provide a setting for enjoying the water without ever leaving home. Carefully built, comfortably appointed and wonderfully situated, this is a distinctive opportunity on Grassy Key. Call today for more information or a private tour.
