Discover the ultimate coastal retreat at 428 Sapphire Drive, a stunning block-construction residence situated on a rare and expansive double lot in the prestigious Sapphire Shores area. A long driveway and winding sidewalk lead you through a beautifully landscaped front yard to this secluded haven, which is set back from the street for maximum privacy. Inside, the home exudes a modern, industrial-chic aesthetic featuring sleek polished concrete floors, soaring vaulted ceilings, and a fresh interior paint palette. The open-concept gourmet kitchen is a focal point, illuminated by a bright skylight and appointed with premium Quartz countertops, abundant cabinetry, and a high-end stainless appliance suite including a Bosch cooktop and refrigerator alongside a KitchenAid double oven. The thoughtful layout offers exceptional flexibility; the current library, featuring a recently replaced north-facing impact window, was originally a third bedroom and can easily be restored to its original configuration. Seamlessly connecting the interior to the outdoor oasis are sliding pocket glass doors that retreat to open the living area to the lanai, offering both an elegant architectural feature and an added layer of protection for the block-construction core. The master suite serves as a private sanctuary with its own bay-facing impact window, a spacious walk-around closet, and a luxurious ensuite bathroom featuring a deep soaker tub and a separate walk-in shower. Significant structural upgrades provide peace of mind, including a new metal roof installed in 2023 and brand-new hurricane-rated garage doors added in 2025. The epoxy-finished garage also comes equipped with a Tesla charging station, catering to modern efficiency. The outdoor living space is a true oasis, fully enclosed by a vinyl privacy fence. Relax in the heated saltwater pool surrounded by elegant Shellock pavers, or enjoy the convenience of the lanai's solar shower. The sprawling backyard is a nature lover's dream, boasting a dedicated butterfly garden, a cozy fire pit, and an irrigation system powered by well water. A versatile detached storage building, currently utilized as a home gym, is equipped with its own air conditioning unit and dedicated kayak storage. Perfectly positioned just minutes from Downtown Sarasota, this home is also a short stroll from the Ringling Museum and the scenic bayfront paths of Sapphire Shores Park.
