Description

Where Casa Marina Charm Meets Modern Island Living. Set on an expansive 10,000 sq. ft corner lot in prestigious Casa Marina, one of Key West's most sought-after neighborhoods, this fully renovated 4-bedroom, 3-bath residence offers nearly 2,100 sq. ft of thoughtfully designed living space just moments from the Atlantic shoreline and the charm of Old Town. A comprehensive 2020 renovation transformed the home from top to bottom, delivering vaulted ceilings, energy-efficient LED lighting, and all-new hurricane-rated impact windows and doors that fill the interior with natural light. The open floor plan flows effortlessly between living, dining, and kitchen spaces, making it ideal for both everyday living and entertaining. At the heart of the home, the chef's kitchen features top-of-the-line Dacor appliances and custom bespoke cabinetry. The private primary suite is tucked at the rear of the home with an ensuite bath and sliding glass doors that open directly to the lanai. Each additional bedroom includes built-in closets, offering comfort and flexibility for guests or a home office. Outdoors, a custom heated in-ground pool with a soothing water feature is surrounded by elegant travertine decking and a spacious covered patio, creating a private tropical retreat for relaxing or hosting under the Key West sky. The low-maintenance front yard features artificial turf and landscape lighting that showcases the tropical foliage after dark. Peace of mind comes standard with a whole-house generator, 2-zone central A/C with linear vents, and a new standing seam metal roof that may qualify for wind insurance credits. A rare one-car garage and ample off-street parking complete this exceptional Casa Marina offering.
