The top 25 floors of the iconic Woolworth Building appear to be on their way to becoming residential apartments or a hotel.

Steve Witkoff’s Witkoff Group and Ruby Schron’s Cammeby’s International have struck a $70 million deal to sell about 184,000 square feet of the skyscraper to real-estate investors David Werner and Joel Schreiber’s Waterbridge, along with an Israeli investor, sources said.

No one returned calls prior to deadline but with just a small deposit on the line, sources familiar with the parties said the deal could still fall apart or be flipped to other investors.

A deal with Werner was first reported by Real Estate Alert in a newsletter.

The Post exclusively reported on April 4 that the owners were for the first time seriously considering offers to sell the building that overlooks City Hall and was once the tallest in the world.

In 1998, Witkoff and Schron paid $137.5 million to the Woolworth Co. successor with an eye on vacating the higher offices for future conversion to residential condominiums or a hotel.

While condominium documents were approved to separate the building into two units, they never moved ahead with apartment layouts or a formal offering.
