Welcome to this exceptional 4-bedroom, 3.5-bath residence overlooking the 10th fairway of The Reserve Golf Course in prestigious St. James Plantation. Ideally located near the main gate and within walking distance of the clubhouse, this thoughtfully designed home offers primarily single-level living, complemented by a private upstairs guest suite with a full bath, dedicated office and abundant walk-in attic storage. The homeowner has recently completed extensive recent upgrades, making this home truly move-in ready. Highlights include brand-new HVAC systems for both the upstairs and downstairs, along with fresh exterior and trim paint, a newly stained back deck, and a newly epoxied garage floor. Beyond these impressive updates, what truly distinguishes this residence is its rare PolySteel Insulated Concrete Form (ICF) construction: a premium building method seldom found in residential homes. Built with steel-reinforced concrete walls and continuous insulation, this home offers exceptional durability, superior energy efficiency, remarkable sound reduction and year-round comfort that far exceeds conventional construction. One of the home's greatest structural advantages is its roof system.

Combined with spray foam insulation, the home maintains consistent indoor temperatures, reduces energy consumption and HVAC demands, provides exceptional resistance to high winds and severe weather and creates a remarkably quiet interior environment. The open-concept floor plan is designed for effortless everyday living and entertaining. At the heart of the home is a chef's kitchen featuring premium appliances, granite countertops, a spacious center island, coffee bar, wine cooler, pantry and extensive custom cabinetry. The adjoining living and dining areas flow seamlessly together, centered around a gas fireplace and opening into a bright sunroom with panoramic views of the professionally landscaped backyard and picturesque golf course beyond. The luxurious primary suite serves as a private retreat, complete with a coffered ceiling, dual custom walk-in closets, a spa-inspired bath, and French doors leading to the screened lanai an ideal place to enjoy peaceful mornings overlooking the fairway.
