About This Home

10987 County Road 905

Discover unparalleled privacy and tranquility in this one-of-a-kind oceanfront estate, a true sanctuary nestled amidst the untouched beauty of the Florida Keys. Tucked behind a private gate, the estate begins with a scenic drive through acres of pristine, preserved nature, leading to your own private island. This secluded haven, like no other in the Florida Keys, was once a source of inspiration for Budd Post—the visionary engineer behind the legendary Card Sound Road. It offers an extraordinary blend of history, natural beauty, and modern luxury. Surrounded by breathtaking 360-degree views, the property's expansive decks and waterfront tiki hut provide unmatched solitude and serenity. Here, you can reflect on days spent exploring the unspoiled waters of the Florida Keys, far removed from the bustle of everyday life. Crafted to perfection, the estate's concrete construction ensures strength and resilience while maintaining an air of timeless elegance. Inside, cathedral ceilings and a grand limestone fireplace create a warm and sophisticated ambiance. The dining room, framed by panoramic ocean views, offers an intimate setting for unforgettable gatherings. Three en-suite bedrooms promise unmatched comfort and privacy, making the home as functional as it is exquisite. This listing includes an additional lot offering even more possibilities and potential. Boasting over 200 feet of concrete dockage, and a private boat ramp, the estate is a boater's dream, offering the perfect gateway to explore the azure waters that surround you. Whether pursuing nautical adventures or savoring the peace of waterfront living, this property delivers an exceptional experience. This private haven is truly like no other in the Florida Keys—a rare gem where luxury, seclusion, and nature converge. Every corner of this secluded retreat invites you to embrace the unparalleled charm of coastal living in an enchanting and one-of-a-kind setting.
