Pre-Construction. To be built. A rare and compelling opportunity to create a custom coastal estate within the prestigious Sanderling Club on Siesta Key, one of the island's most private and sought-after enclaves. Set on an expansive .70-acre homesite, this future residence will feature a thoughtfully designed footprint spanning 4,294 square feet under air and over 6,400 total square feet, offering a refined blend of scale, comfort, and architectural presence. Positioned to capture desirable southern exposure, the property enjoys a serene natural backdrop, creating a setting rich in privacy, wildlife, and unobstructed beauty. The home will be delivered with the structural framework and layout in place, while allowing the future owner to curate finishes, materials, and design details to their exact vision, resulting in a truly personalized luxury residence. The Sanderling Club is renowned for its understated elegance and unmatched seclusion, offering 24-hour guard-gated security and a lifestyle centered around privacy and connection to nature. Residents enjoy access to tennis and pickleball courts, a private marina, and a historic beachfront clubhouse with exclusive access to the powdery white sands of Siesta Key Beach. Quiet, secure, and distinctly refined, this is an extraordinary chance to bring your vision to life within one of Sarasota's most coveted coastal communities-where luxury is defined not only by design, but by space, serenity, and discretion.
