The building is currently under construction and, according to a WSJ report, is set to be completed by the third quarter of 2019.
The unfinished building's penthouse, which will be listed at $68 million, is already poised to shatter Florida's real estate record, which was set by the sale of a $60 million penthouse in 2015.
The penthouse is designed by architect Renzo Piano, who has designed iconic buildings such as the Centre Georges Pompidou in Paris.
The apartment complex is about an hour's drive north of the most expensive zip code in Florida, Fisher Island, a 126-acre man-made island that's considered the most millionaire-dense zip code in America.
