About this House

New construction waterfront living in the heart of Coco Plum. This beautifully designed 4-bedroom, 3-bath residence combines modern coastal style, exceptional outdoor living, and direct boating access in one of Marathon's most desirable waterfront neighborhoods.

Thoughtfully positioned to take advantage of the setting, the home offers expansive open-water views from nearly every room and a bright, open-concept layout designed for both everyday living and entertaining. The main living level features a spacious living and dining area surrounded by natural light and water views, along with two guest bedrooms and a full bath.

Upstairs, two generously sized primary suites each feature private en-suite baths and elevated panoramic views, creating peaceful private retreats above the water.

Outdoor living is a true highlight, with three covered terraces spanning both levels, a large resort-style pool, and a convenient poolside prep station with sink and storage. Whether hosting guests, relaxing by the pool, or enjoying a quiet morning overlooking the water, the home is designed to embrace the Florida Keys lifestyle.

Boaters will appreciate approximately 50 feet of deep-water dockage with quick ocean access, along with a fish-cleaning station, bait freezer, and covered parking for added convenience.

Ideally located near Coco Plum Beach and just minutes from Marathon's dining, shopping, and attractions, this newly constructed waterfront residence offers an exceptional combination of modern comfort, boating access, privacy, and island living, perfect as a full-time residence, vacation retreat, or investment property.
