Luxury Estate Home on a large gated Gulf-front homesite offering exceptional privacy, scale, and timeless coastal elegance. Meticulously maintained as a cherished family retreat, this extraordinary residence has never been rented and offers a level of care, condition, and custom quality rarely found in today's luxury coastal market. Custom built by Windolf Construction and positioned on two combined lots—a Gulf-front lot plus an additional 1st-tier lot—this estate-sized property encompasses 5,000+ heated and cooled sq ft and more than 8,000 sq ft under roof including expansive decks, all designed to capture unobstructed Gulf views and sweeping Bay views to the east. The home features 5 bedrooms, 6 full baths, and 1 half bath, with each bedroom offering a private ensuite bath and deck access. Soaring ceilings, walls of glass, a fireplace, and expansive open living spaces create a dramatic setting for entertaining. The chef's kitchen is appointed with high-end appliances, custom cabinetry, a butler's pantry, and generous dining areas designed for hosting on a grand scale. Multiple living and dining spaces open onto spacious Gulf-front decks for seamless indoor-outdoor living. A private elevator services all levels, including the spectacular top-floor primary suite retreat spanning more than 1,800 sq ft. This private sanctuary features a sitting room with Bay views, a Gulf-front deck, and a spa-inspired bath with soaking tub, walk-in shower, and custom cabinetry. The oversized two-lot setting offers exceptional outdoor space with room to add a private pool, while the flexible floor plan presents the opportunity to create a 6th bedroom or additional bunk/flex space. Located on a quiet stretch of beach just steps from the neighborhood pool, this legacy Gulf-front estate is a rare opportunity to own one of Cape San Blas' most private and distinctive luxury properties.
