After years of speculation, the developer behind the Woolworth Building's condo conversion has put a price-tag on living at the top of NYC's oldest and grandest skyscraper: $110 million. (Now, read this.)

Bloomberg reports that the $110 million was disclosed in "a proposed offering plan filed with New York State Attorney General Eric Schneiderman’s office." Appraiser Jonathan Miller said it was the highest price for a lower Manhattan residential home, "The price is more reflective of the unique historical nature of the property... We’ve seen rapid absorption downtown, but this project is unlike anything that’s come online." Completed in 1913, the 58-story limestone building designed by Cass Gilbert has neo-Gothic and Art Deco touches, including the elaborate roof and terra-cotta details framing windows.

Alchemy Properties is developing the top 30 floors which will house 34 apartments—from Bloomberg:

Prices for the condos start at $3.5 million for a 1,209-square-foot (112-square-meter) unit on the 44th floor, according to the proposed offering plan, which is under review by the attorney general’s office. Three units in addition to the penthouse are listed at more than $20 million, including a 6,084-square-foot full-floor apartment with a terrace on the 31st story for $24 million.

The $110 million penthouse is about 8,975 square feet with a 584-square-foot terrace. The four-bedroom condo with a private elevator spans nine stories, with the primary living space on the 50th and 51st floors, according to the offering plan. A great room and wine cellar make up the 53rd floor, and the 55th through 58th levels in the cupola include a library or media room and an observation deck at the top, the plan shows.

You could also just buy a penthouse topped with two cupolas for the low price of $20 million.

When Alchemy president Ken Horn was interviewed by CBS News, he was asked "What does the luxury customer who will buy in a building like this want?" Horn replied, "The best kitchen you can imagine. The most spectacular bathrooms. They're gonna be spectacular pieces of art." He also likened the penthouse to a "castle in the sky. We can't think of anything in the world that will be similar to that."
