NYC's 'Mansion in the sky'

Designed by Juan Pablo Molyneux, one of Architectural Digest’s AD100, the apartment occupies the 73rd, 74th, and 75th floor of the CitySpire, has 8,000 square feet of interior space, and 3,000 square feet of external space. There are stunning 360-degree views from the highest terraced apartment in New York. (Photo by Evan Joseph/Prudential Douglas Elliman)

Guests must enter the home via a private elevator that connects the three floors (though, there is also a mahogany staircase.) Just beyond the formal entryway on the 73rd floor sits a magnificent dining room, which comfortably sits more than 20 guests. Around the corner is a large media room, silver closet, and two powder rooms. (Photo by Evan Joseph/Prudential Douglas Elliman)

Off the dining room on the 73rd floor sits a 15-foot by 30-foot eat-in chef’s kitchen. A butler’s pantry outfits the kitchen, and a nearby wine room can hold 1,000 bottles. (Photo by Evan Joseph/Prudential Douglas Elliman)

Upstairs, three spacious guest rooms, each with an en suite bathroom, also offer overnight visitors picturesque views of Manhattan from another wraparound terrace. The floor also includes a formal gallery, conference room, and private study. (Photo by Evan Joseph/Prudential Douglas Elliman)

Off the giant, 19-foot by 16-foot master suite on the 75th floor, there is an equally magnificent – and sizable – master bathroom, outfitted with hunter green marble, mahogany finishes, and bronze fixtures. It’s hard to miss the deep, soaking tub and extra-large steam shower for two. (Photo by Evan Joseph/Prudential Douglas Elliman)

Classic details are not spared in this penthouse. Check out the Versailles-patterned chestnut floor, complemented by the ornate crown moldings and coffered ceilings in a sitting room adjacent to the master suite. (Photo by Evan Joseph/Prudential Douglas Elliman)

Guests are greeted by a gracious, formal entry foyer, adorned with inlaid marble floors and elegant columns, on the 73rd floor. (Photo by Evan Joseph/Prudential Douglas Elliman)

The apartment’s circular configuration gives tenants and guests exclusive views of Central Park, Midtown Manhattan, the Hudson River, and well beyond. (Photo by Evan Joseph/Prudential Douglas Elliman)

Breathtaking views like this can be enjoyed not only from behind the penthouse’s windows, but each of its three floors has a wraparound terrace for tenants and visitors to enjoy grand vistas of the city. (Photo by Evan Joseph/Prudential Douglas Elliman)

The CitySpire condominium sits in the heart of New York City, and offers amenities such as a 24-hour doorman-concierge, a live-in resident manager, a fitness center and 50-foot pool, and a garage. Carnegie Hall and the famed Fifth Avenue shopping district are nearby, as well. (Photo by Evan Joseph/Prudential Douglas Elliman)

But views like this don’t come cheap. The buyer is going to need to put a down payment of 10 percent -- that’s $10 million. And, beyond the monster price, the buyer must be ready to shoulder a monthly real estate tax bill of more than $10,000 and a maintenance fee of $8,618.

Built in 1988, the CitySpire became New York’s tallest mixed-use building. Helmut Jahn, of the Chicago-based architectural firm Murphy/Jahn designed the structure. The building features commercial space on its lower 24 floors, and is capped by the recognizable domed space. (Photo by Evan Joseph/Prudential Douglas Elliman)
