• Floyd Mayweather has announced a new sky-high project.
  • The retired boxer is working with his “real estate buddies” on One Vanderbilt, a skyscraper currently under construction in New York City.
  • It is unclear how involved Mayweather is with the building, but he claims to be “putting an observation deck” on the structure.
  • Mayweather retired from boxing after scooping a billion dollars in career earnings in 2017.

Even the sky is no limit for retired boxer Floyd Mayweather.

The former five-weight world champion retired undefeated after 50 professional bouts last year and has developed interests in gambling, strip club ownership, and property.

Mayweather has long had sky-high plans but his latest project is unlike any other as the 41-year-old has said he is involved with One Vanderbilt – a skyscraper currently under construction in New York City.

"I've been working with my real estate buddies, my real estate guys," Mayweather said to YouTube channel Fight Hype.

"The project I'm working on now is called One Vanderbilt. Its going to be the tallest building in New York City. It's going to be taller than the Empire State building. We are also putting an observation deck on the building."

Mayweather claims One Vanderbilt will tower over all others in the city but, when completed in 2020, it will top 1,301 feet and therefore be just shy of 432 Park Avenue and One World Trade Center.

Mayweather appears to have given up on a UFC deal

Mayweather has not competed since his 10th round stoppage victory over UFC fighter Conor McGregor in 2017, a fight that sent his career earnings to a billion dollars, according to Forbes.

He announced his retirement from boxing shortly after the bout but considered a return to the fight game as he teased a potential billion dollar deal with leading mixed martial arts promotion UFC earlier this year.

However, those plans now appear to be dead in the water as Fight Hype quote Mayweather to have said that he is "through" with fighting.
