Peek at the floorplans for the Crown Building’s $100M penthouse

The five-story penthouse that will eventually occupy the "crown" of Fifth Avenue’s lauded Crown Building, at the corner of 57th Street and Fifth Avenue, is unsurprisingly going to be a showstopper. The only question is if a buyer will fork over $100 million to live there.

The Real Deal has gotten its hands on floor plans for the nearly 14,000-square-foot pad, which will hold a show kitchen and a working kitchen, a piano lounge, two swimming pools, a full-floor master suite. The top floors of the mixed-use tower are being converted into an ultra-luxury condo alongside an Aman-branded hotel by the Russian developer Vladislav Doronin.

Per the floorplans, which come from the condo offering filed with the Attorney General’s office, there’s a gallery on the first floor, surrounded by a wraparound terrace and outdoor pool. The dining room, family room, and both kitchens are one flight above. There are four bedrooms and a game room on the third floor, while the master suite will span the entire fourth floor. Last but not least, the top floor of the penthouse has a second indoor pool, lounge, and steam room.

Exact pricing has yet to be released, but the developer has hinted that it'll cost north of $100 million. The rest of the condos will also be plenty pricey—a 1,149-square-foot one-bedroom is expected to go for $5.9 million, while a different one-bedroom with a separate office or den area and two bathrooms is poised to seek $10.6 million. A 4,384-square-foot three-bedroom, two-bathroom will ask $26.6 million, and a four-bedroom, five-bathroom apartment measuring 6,287 square feet is poised to ask $58.3 million.

In total, the neoclassical Beaux-Arts structure at 730 Fifth Avenue will be converted into 83 hotel suites (each over 750 square feet and with a fireplace) plus 20 luxury condos.

The hotel is also expected to have a three-story spa spanning 22,000 square feet—with an indoor swimming pool surrounded by fire pits and lounging areas—as well as an Aman member’s club, cigar bar and eateries. Condo residents will have access to those amenities, too. And if one piano lounge isn't enough for the future buyer of the penthouse, the building will have a so-called Sky Lobby with its own piano bar, plus a subterranean jazz bar and two restaurants.
