AND another one bites the dust.

The white modernist, single-purpose Milliken Building at 1045 Avenue of the Americas, across from Bryant Park, is turning into vacant land.

The eponymous owner, a South Carolina-based chemical and textile manufacturer, has not used the eight-story building for “years,” and whatever the company does with the tract, a spokeswoman said, “will be as of right.”

However, the company has not yet made a decision about what to build on the 14,101 square foot plot.

The previous building was 120,000 feet, but zoning can allow for a larger tower.

A Landmarks Commission spokeswoman said the owners secured a demolition permit before it was formally reviewed for potential landmark status.

However, she noted that the building did not appear on a list of “important” modernist structures compiled by prominent architect and Yale School of Architecture Dean Robert A.M. Stern.

The building’s architect was Carson & Lundin, the same firm responsible for the Rockefeller Center area buildings, 600 and 666 Fifth Avenue and 75 Rockefeller Plaza.

In a statement, Milliken’s spokeswoman said, “Milliken & Co. has been a distinguished corporate citizen in New York for the better part of a hundred years and remains committed to this great city. We’re very optimistic about the future and look forward to seeing an architecturally distinctive building on our Midtown site that will be a great addition to the vibrant Bryant Park neighborhood.”
