The penthouse residence at Gulfside Twelve, Unit 402, stands as the crown jewel of this intimate beachfront enclave, offering an exceptional level of privacy, scale, and elevation rarely found on the island. This one-of-a-kind residence features approximately 4,000 square feet of refined interior living, a 700 square foot private lanai, and an extraordinary 2,000 square foot private rooftop terrace, creating nearly 6,000 total square feet of curated living space with panoramic Gulf and island views. Designed by Clive Daniel Homes in collaboration with PDS Architecture, the interiors are defined by custom tile and wide-plank architectural wood flooring, selected for both durability and timeless sophistication, along with elegant marble surfaces, including marble countertops that anchor the home in enduring luxury. The chef's kitchen is a statement of refined discretion, featuring a premium Thermador appliance suite with fully paneled, virtually invisible refrigeration, an oversized designer tile backsplash, a dramatic cabinetry-wrapped hood, propane gas range, wine refrigerator, ice maker, and an expansive walk-in pantry. The primary suite is a private retreat, offering spa-inspired finishes, an oversized walk-in shower, and a dedicated makeup vanity designed for daily indulgence. A fireplace anchors the main living area, while impact-resistant sliding doors frame sweeping Gulf-front views at the front of the residence and tranquil canal views at the rear, with access to Estero Bay. This penthouse is further distinguished by elevator access that opens to a private entry foyer, creating a true sense of arrival and enhanced privacy. Additional features include two garage parking spaces, additional private storage, private beach access, and exclusive use of the community's luxury pool and spa. The private rooftop terrace elevates the experience even further, offering panoramic Gulf and island views ideal for sunset entertaining, quiet mornings, and unparalleled privacy above it all.
