Vertical construction is nearly complete for Red Apple’s 46-story condominium tower, The Residences at 400 Central, as crews have reached the 43rd floor with a new floor being added every six days.

New York billionaire John Catsimatidis Sr., founder of Red Apple Group, and select media members gathered at the tower site on Monday morning for a ceremonial topping out celebration.

“I wanted to build something in honor of Margo’s parents who’ve been coming to St. Pete for 40 years,” said Catsimatidis Sr. “My only regret is that I did not invest sooner.”
