There’s also a roof deck, complete with panoramic views, spanning more than 1,000 square feet.

The home, currently, is all open, as it was purchased with the intent of displaying the previous owner’s massive art collection, which comprised roughly 2,000 pieces, and included works by Pablo Picasso, Jeff Koons, and Joan Miró. The family purchased it after searching for a decade for the perfect space — accordingly, the home is in need of renovation and is priced as such—but it’s estimated that it could be outfitted with six bedrooms and six bathrooms. Given its size, the property could be used as a residence or even for an organization, such as a foundation, too.

The home has a rich history, too. It was originally constructed in 1898 by developer James Carlew and designed by architectural firm Cleverdon & Putzel. It’s located a half-block from Central Park and one block away from the American Museum of Natural History. Owners will also be near Lincoln Square, the Beacon Theatre, and numerous restaurants and stores along Broadway.
