Millennium Tower’s largest unit, the “Grand Penthouse,’’ has a buyer and is under agreement, according to the developers behind the tallest residential building in Boston.

The 13,000-square-foot condo takes up the entire top floor of the 60-story Millennium Tower and had a $37.5 million price tag when first announced.

The project’s developers, Millennium Partners, said in a statement that the buyer’s name and the purchase price would not be released. They did say that the buyer intends to use the space as a family residence.

If the closing price for the penthouse is even close to the listing price, however, it would become by far the most expensive home sale in Boston’s history.

To date, Boston saw its most expensive home sale ever in 2015 at 300 Boylston Street, Unit #1005-1006, which went for $15.4 million dollars.

The Grand Penthouse is 625 feet above the street level with floor-to-ceiling windows that will give 360-degree views of Boston. There is also a 2,000-square-foot outdoor terrace.

90 percent of the 442-unit Millennium Tower is now under contract, and the building is set to open in summer 2016.
