The side-by-side residences, which are both still being built, were purchased by an anonymous American buyer for a price that represents the biggest condo sale ever in Miami.
Part of the Residences at the Miami Beach EDITION resort being developed by Schrager in partnership with Marriott International, the penthouses will sit 16 stories atop the Miami Beach EDITION hotel.
Each unit is spread over three levels and more than 16,000 square feet of living space, including more than 6,000 square feet of outdoor space.
Both units boast eight bedrooms and eleven bathrooms and 360-degree views of Miami, the bay and the ocean. Other notable amenities include private elevators providing access to every floor, a rooftop garden with private swimming pool, outdoor kitchen and glass-enclosed dining area.
Residence owners will have access to all of the EDITION hotel amenities, including a gourmet restaurant, a nightclub, a bowling alley and an ice skating rink.
The penthouses are due to be completed next month.
