1378 MARIAN Drive Over an acre. Over 5, 000 square feet. On Amelia Island. This is the kind of property that almost never becomes available. Tucked away on a quiet dead-end street that ends at the Intracoastal, this extraordinary this estate sits on a rare 1.02-acre on-island homesite beneath some of the most majestic 200-year-old oaks on Amelia Island. Just steps from the beach, bike path, Amelia River Golf Course, and Harris Teeter, the setting offers unmatched convenience with complete privacy. Featuring 6 bedrooms, 6 full bathrooms, and 2 half baths -- including four en-suite retreats -- this home was thoughtfully designed for elevated everyday living and unforgettable gatherings. The main-level primary suite offers direct pool access, while every upstairs bedroom opens to a private second-story deck overlooking the backyard oasis. A separate-entry guest wing with two bedrooms, two baths, and a studio with laundry creates exceptional flexibility for extended family, guests, or multi-generational living. Inside, you'll find not one but two expansive living areas on the main level -- each with soaring ceilings, oversized gourmet kitchens, separate entrances, and seamless pool access. Designed for large-scale entertaining, the open-concept layout offers generous bar seating, lounge space, and room for farmhouse-style dining -- all while providing breakout spaces to unwind, recharge, or host with ease. An electric fireplace adds warmth and ambiance to the main living space. The backyard is truly spectacular. A resurfaced heated pool (2020) anchors the space, complemented by a covered and waterproofed patio, outdoor shower with dedicated hot and cold water, fire pit, Green Egg, and a massive fully fenced yard with tractor gate access. There's ample room for a future pickleball court, and an existing large concrete pad makes hot tub installation simple. A new 30x12 shed, attic storage, and multiple oversized closets ensure abundant storage throughout. Completely renovated down to the studs in 2020, this home offers peace of mind with all new plumbing, electrical, HVAC systems (plus a large upgraded HVAC in 2022), new septic tank (2020, pumped 2025), new pool pump (2025), new well pump (2025), new roof (2019), and two Rinnai tankless water heaters. The entire interior was freshly painted, the exterior pressure washed, and landscaping professionally refreshed within the past month. The large pull-through paver driveway provides extensive parking for guests, boats, or recreational vehicles -- a rare island luxury. Furnishings are negotiable, offering a true turnkey opportunity. Private. Expansive. Fully renovated. This is Amelia Island living at its finest.
