A deal was struck two years ago to turn the neo-Gothic tower of the Woolworth Building into luxury condominiums, creating an unusual opportunity for wealthy apartment-hunters to own a piece of one of New York’s most recognizable landmarks.

Now, just a few doors down from the 101-year-old building at 233 Broadway, the sales office is poised to open. Inside, an opulent model apartment will harken to another age, with prewar proportions, dark herringbone floors and marble-clad bathrooms.

W motifs appear throughout — on doorknobs and marble kitchen backsplashes. They were cast from the original logos on the elevators, lest prospective buyers forget where they are.

“We didn’t want people to walk in and feel like they could be in an anonymous skyscraper,” said Kenneth S. Horn, the president of Alchemy Properties, which is reinventing the top 30 floors of the copper-domed skyscraper, designed by Cass Gilbert and the world’s tallest when it opened in 1913. “As opposed to many new buildings where you get a white box, we very much wanted people to know ‘I am living in the Woolworth Building.’ ”
