Thoughtfully designed by acclaimed Amelia Island architect John Cotner and built by Ed Freeman of Great Capes Builders, this custom Lowcountry home offers timeless coastal style, exceptional efficiency, and the kind of porch living that defines the South. Enjoy a welcoming front porch gallery and a large screened back porch with grilling area in Cumberland Harbour, near the Intracoastal Waterway on the Georgia-Florida line. A desirable split-bedroom floor plan offers privacy and easy living, featuring a great room with an ISOKERN fireplace, built-ins, hardwood flooring, custom millwork and cabinetry, and Andersen windows throughout the main living spaces. Meaningful upgrades include a whole-home generator supported by a 500-gallon propane tank, geothermal heating, and storm shutter systems (hard and soft) for streamlined seasonal preparedness. A first-floor study with French doors creates a dedicated workspace connected to the heart of the home. Upstairs, a bonus room with a full bath adds flexible space for guests, hobbies, or a media room. An additional standout feature is the 1,183 sq ft walk-up attic-fully floored, conditioned, and sheetrocked-perfect for storage today and ready for future expansion. The kitchen is designed for everyday function and gathering with abundant maple cabinetry, generous counter space, and an oversized island that connects the great room. A butler's pantry and a walk-in pantry create effortless hosting and excellent storage. Set among mature trees and flowering shrubs with classic live oaks and Spanish moss, the setting is peaceful and low-maintenance. Convenient to historic downtown St. Marys, approximately 35 minutes to JAX airport, and about 45 minutes to Mayo Clinic and Jacksonville shopping, dining, and entertainment.
