An Architectural Scion is Reborn. Restrained Opulence!
Experience the pinnacle of Downtown luxury in the Penthouse at 170 Fifth Avenue, and historic landmark building.
Crowned by an iconic golden dome cupola, the Sohmer Piano Building is Architect, Robert Maynicke’s most extravagant work on this stretch of Fifth Avenue—a veritable Renaissance rocket ship soaring up from its double-story rusticated piers to an octagonal spire, shaping the city’s inimitable skyline.
This discreet penthouse, adjacent to the Flatiron building, has been completely renovated, blending true old-world charm with a twist of new development. The entire roof deck is deeded privately, offering a space to marvel at the city. Spanning over 5000 sqft, the residence features an open-concept design with soaring ceilings and windows that frame breathtaking views of the city skyline. The standout feature is the golden dome cupola—a private sanctuary that offers panoramic, 360-degree views of New York City, including landmarks like the Empire State Building, the Flatiron Building and Madison Square Park.
Inside, the penthouse boasts a gracious eat-in- kitchen with all the premium appliances, expansive living and dining areas that flow effortlessly, and a private rooftop space perfect for al fresco dining with the city as your backdrop. There are two grand foyers connected by a circular baronial limestone staircase and framed by more than 40 oversized windows. An 80-foot expanse of greenhouse-style set of windows on the upper level reveals an abundance of natural light and stunning views of Manhattan landmarks.
The corner primary suite offers a luxurious private retreat, featuring three directions of exposure, 35+ linear feet of closet space, leading to a spa-like bathroom with a Waterworks soaking tub. The additional three bedrooms provide flexibility for a home office or guest accommodations, all designed with the same attention to detail, views, and discerning consideration for a luxury lifestyle.
Owning this penthouse is not just about living in one of Manhattan’s finest residences—it’s about living in a piece of New York history.
