A breathtaking tribute to the grandeur of Renaissance Venice, Serenissima—meaning “The Most Serene”—stands as one of Florida’s most revered residences. With its coveted architectural detail and Gulf-front address, this palatial estate is unmatched in design splendor, craftmanship, and artistry. Gracing the southern tip of Longboat Key, endless views of sea, sand, and sky create an unforgettable backdrop for living. From the moment of arrival, Serenissima exudes elegance and beauty. A soaring marble hall crowned by a glass sky dome sets the stage for lively evenings with family and friends. Looking west, the shimmering Gulf of Mexico dazzles from nearly every room and stretches endlessly beyond the horizon. Majestic in scale yet intimate in nature, Serenissima offers grand spaces for lavish entertaining alongside serene retreats for private relaxation. Elements of bespoke design include a magnificent grand salon capable of hosting 100 guests, a gourmet chef’s kitchen perfect for gathering and conversation, a 10-seat home theater, and a light-filled sun room overlooking the infinity-edge pool. Six bedrooms and eight baths offer a private retreat for the whole family. Crafted with reverence for old-world artistry, the home features exquisite Venetian murals, dazzling chandeliers, and masterful millwork across three levels of luxurious living. For the car enthusiast, Serenissima’s ground level garage/car gallery comfortably fits 12 vehicles. Outdoors, the sophisticated architecture and landscape design perfectly complement the coastal location. Days here are filled with sun-drenched adventures—beachcombing, sailing, kayaking, or golfing —followed by unforgettable sunsets. Expansive terraces offer panoramic vistas over the pool, pristine beach, and shimmering turquoise Gulf waters. Located within the prestigious gates of The Longboat Key Club, members enjoy world-class amenities including golf, tennis, dining, a spa, fitness center, and a full-service marina. Just over the bridge, enjoy the world-class destinations of downtown Sarasota where opera, ballet, symphonies, and theater enliven everyday living. Serenissima is a one-of-a-kind legacy estate on Florida’s Gulf Coast, a stunning reflection of a life well lived.

A stunning ode to the majesty of Renaissance Venice, Serenissima “The Most Serene” is one of the finest homes ever built in Florida. Incomparable in architecture, irreplaceable in artistic beauty and situated on the southern end of the coveted Longboat Key, this palatial masterwork embraces a luminous panorama of sea, sand and sky. Engaging all of the senses, a marble-clad hall soars to a glass sky dome, while before your eyes the azure Gulf of Mexico melts into the horizon.

These include a magnificent grand salon, which could easily accommodate 100 guests, a master chef’s kitchen ideal for congregation and conversation, 10-seat theater and Sun Room adjacent to the pool. At Serenissima, active days of sand castle building, shell seeking, sailing, kayaking, golfing or theater-going are capped by spectacular sunsets enjoyed from expansive terraces with incredible views spanning the infinity pool, beach and Gulf.
