NEW YORK (CBSNewYork) — It’s known as one of the most unique homes in Manhattan.

The old police building, built in 1909, served as the NYPD Headquarters until 1973. The four-story penthouse is located at 240 Centre Street in Nolita.

“The next buyer is actually buying a piece of art, which is the most remarkable part,” Kevin Brown, of Sotheby’s International Reality, told CBS2’s Emily Smith.

The current owner bought the penthouse from Calvin Klein. The main floor has an informal family room, a cozy dining room, and the main kitchen.

“All the floors are heated, everything you’d expect from any other luxury property. As you ascend the stairs, you are going to have more and more of a ‘wow’ factor,” Brown said.

CBS2 took the staircase to the master suite, although an elevator was an option as well. The master takes up the entire second floor.

“[This is] a great master suite in terms of size,” Brown said.

The closet in the suite is more of a dressing room, with space larger than some New Yorkers’ apartments.

From the closet, you enter the master bathroom with a heated mosaic tile floor and a large soaking tub. A spiral staircase bring you to the heart and soul of the penthouse.

“You’re in the dome, the 32-feet in diameter room has four huge windows and lets in amazing light,” Sotheby’s Craig George explained.

From the terrace, you can see 360-degree views of Manhattan and every iconic building you can imagine. A custom-made staircase of steel and oak had to be crained up through the windows due to its size. It’s old Hollywood glamour.

“[NYPD] discovered this room upstairs when they were fixing the clocks, and all of a sudden a whole other room up here that no one knew about!” George said.

It’s all exposed brick, with 35-foot high ceilings.

“It’s rare, one-of-a-kind. It reminds of Rome… It feels ancient and original,” George said.

To live large in the former police headquarters penthouse, it will cost you $35 million.
