A South American buyer is in contract to pay a cool $55 million for an oceanfront penthouse duplex in Miami — and it isn’t even built yet.

The penthouse duplex is in the North Tower of the St. Regis Residences in Sunny Isles Beach, Florida.

At 750 feet tall, it will be South Florida’s tallest residential building on the ocean when completed, designed by Arquitectonica with interiors by São Paulo, Brazil-based designer Patricia Anastassiadis and landscape design by EDSA. It’s scheduled for completion at the end of 2027.

If the posh penthouse deal closes, it will be a record for the neighborhood.

The condo, on the 61st and 62nd floors, was last asking $60 million. It’s a massive 9,843 square feet, and comes with an additional 8,822 square feet of outdoor space that includes a private pool, a Jacuzzi and a summer kitchen.

Inside, the home boasts four bedrooms plus a home office, seven baths, two powder rooms, 12-foot ceilings and plenty of floor-to-ceiling windows. Residences in the building start at $4.5 million, while units in the building’s South Tower begin at $5.6 million and are already 80% sold, according to developers Fortune International Group & Château Group. 

Amenities include pickleball and padel courts; a gym; a therapeutic wellness pool; a private lounge areas for adults, kids and teens — and more. There will also be a private beach club, three ocean-facing pools with cabanas and a sunset pool deck with an infinity-edge pool, along with a resident’s club and the Ellipse Club, which includes a cognac room, a wine bar and gaming rooms.
