Under Construction. Set on nearly two private Gulf-front acres, this visionary estate is emerging as one of the most architecturally significant residences ever conceived on Longboat Key. Designed by the internationally acclaimed firm Sweet Sparkman Architecture & Interiors, the home represents a rare convergence of sculptural design, coastal sensitivity, and modern livability. Bold in concept yet timeless in execution, the main residence unfolds with intention. A dramatic foyer introduces expansive living spaces designed to capture light, scale, and uninterrupted Gulf views. The primary suite is conceived as a private sanctuary, complete with dual spa-inspired baths and bespoke dressing rooms. A stately office, refined lounge, formal dining room, and temperature-controlled wine cellar complement the open-concept great room, which transitions seamlessly to a sweeping Gulf-front terrace. Dual kitchens, a showpiece entertaining kitchen and a separate chef's kitchen, elevate both daily living and grand-scale hosting. The estate continues upward to a rooftop deck with panoramic coastal vistas, while other levels offer a private cinema, multiple guest suites, and a dedicated guest-level kitchenette. A thoughtfully designed guest house and separate pool house provide additional privacy and flexibility for extended stays or staff accommodations. Outdoors, the setting transforms into a private coastal resort. Lush, layered landscaping surrounds a dramatic resort-style pool and spa, expansive entertaining terraces, tranquil water features, and potential for a private tennis and pickleball court - all oriented toward the Gulf's endless horizon. Positioned along one of the most coveted stretches of Longboat Key, the property offers both seclusion and proximity to the best of the region, including The Resort at Longboat Key Club, The St. Regis Longboat Key Resort, St. Armand's Circle, and the cultural vibrancy of downtown Sarasota. With construction advancing and pricing evolving accordingly, this is a rare opportunity to secure a generational Gulf-front legacy estate at a pivotal stage. Longboat Key's global recognition, including its inclusion among Forbes Travel Guide's Top 12 Destinations, further underscores the enduring value of this extraordinary offering.
