On the quiet and coveted stretch of North Casey Key, where century-old oaks meet the shoreline, and the land unfolds uninterrupted from Gulf to bay, this extraordinary 1.5-acre estate offers a rare opportunity to steward one of the island’s most incredible homesites. With 180 feet of private Gulf frontage and exceptional depth across to the intercoastal, the property is defined by its scale, privacy, and quiet permanence—offering a setting that feels both expansive and deeply secluded beneath a canopy of mature coastal forest. Here, the rhythm of the water and the natural beauty of the land create an environment that cannot be replicated. The existing improvements include a Gulf-facing main residence, originally constructed in the early 1970s, thoughtfully positioned to capture sweeping views in both directions. The two-bedroom, two-bath home features elevated ceilings, expansive windows, and a sunlit central courtyard designed to bring light and the surrounding landscape into everyday living. A separate guest house, completed in 2002, provides two additional bedrooms and baths, bamboo flooring, Bahama shutters, a versatile bonus room, and an oversized two-car garage—offering flexible accommodations for guests, or interim use while renovating or building. A recently installed private dock completes the property’s rare Gulf-to-Bay lifestyle and provides immediate access to boating and waterfront recreation. While the existing structures offer renovation potential and immediate livability, the true and enduring value lies in the land itself. Homesites of this magnitude—spanning Gulf to bay with this level of frontage, privacy, and natural beauty—are rarely available. Conceptual plans by Potter Homes envision a timeless coastal estate exceeding 6,500 square feet under air, thoughtfully designed to preserve the character of the land while capturing panoramic water views and creating a residence of lasting architectural significance. Whether preserved, renovated, or reimagined entirely, this is more than a homesite—it is the foundation for one of Casey Key’s next great estates, and an opportunity to create something that will endure for generations.
