This extraordinary tri-level masterpiece presents a bespoke private rooftop terrace, on e of the largest in Miami Beach, spanning over 11,000 sf of outdoor living, commanding unobstructed 360-degree panoramic views across every horizon. The private rooftop sanctuary is designed for grand-scale entertaining and elevated everyday living, featuring a saltwater pool, expansive sun lounges, a professional-grade outdoor kitchen with BBQ, dining for 18, a fire pit, and multiple wraparound terraces across all levels, creating a seamless indoor-outdoor lifestyle at an unprecedented scale. Two sculptural floating staircases, illuminated by dramatic skylights, connect the residence’s three levels. Soaring 20-foot floor-to-ceiling glass walls frame breathtaking vistas from sunrise to sunset, capturing the Atlantic Ocean and pristine beachfront, cruise ships gliding past Fisher Island, sweeping open bay views, and Miami's skyline sunsets. The grand principal suite is a private retreat encased entirely in glass, showcasing a spa-inspired bath with a floating shower and soaking tub, multiple walk-in wardrobes. The PH also offers two family rooms, two wine cellars, a bar lounge, billiards room, and private gym. Completing the offering is a private 7 car garage. This is a world-class legacy estate at the very to of Miami Beach.
