Not a suburban house, but a maisonette unit at 18 Gramercy Park South! (Brown Harris Stevens) Not a suburban house, but a maisonette unit at 18 Gramercy Park South! (Brown Harris Stevens)
In New York City, the vast majority of apartments are single-story homes. However, with a growing number of boutique developments including duplex units (most commonly the maisonette or penthouse, though units in between are not uncommon) and/or townhouse units among the condominiums, duplex apartments are becoming more common and introducing more staircases to the city’s market. Moreover, while it is far more common for buyers to purchase two horizontally adjacent units to combine apartments, vertical combinations are not unheard of, but do require the installation of a staircase.
In any instance, these apartments offer the atmosphere of a single-family home with all the amenities and services of a condominium. In this age of hybrid office environments, this environment can allow for greater separation of work and relaxation if a home office space can be set up on a separate floor from the bedroom. Indeed, one of the most common layouts is to put the main entertaining space on one floor and the bedrooms on another.
While such an arrangement allows for excellent privacy, it might offer a little too much separation for the parents of small children. Additionally, the elderly and people with physical disabilities would be well advised to avoid apartments with staircases. This is especially true of apartments with floating staircases, which have come to be seen as a hallmark of modern interior design, and spiral staircases that rise vertically around a central support rather than eating into precious square footage. Some especially well-heeled buyers, like the ones who purchased a massive combination unit at The Bellemont with a $66.5 million ask, opt to install an elevator in addition to a staircase; but between finances, square footage, and a building's infrastructure, this isn't an option for everyone.
Below, we take a look at apartments with staircases separating both levels. Additionally, a number of recently constructed and newly converted buildings alike have incorporated dramatic staircases into their common areas, meaning residents can’t help but make a dramatic entrance into the amenity space.

108-Leonard-Street-01 108 Leonard Street (Douglas Elliman)
Amidst the conversion of "the Clock Tower Building" from the New York Life Insurance Company headquarters to a star-studded condominium, the exteriors were restored while the interiors were transformed to meet the standards of today’s buyers. They include a dramatic double-height lobby with bifurcated staircases leading to a mezzanine overlooking the entrance.

277-Fifth-Avenue-01 277 Fifth Avenue (Elliman)
277 Fifth Avenue dethroned Trump Tower as the tallest residential building on Fifth Avenue and was an instrumental player in NoMad's residential renaissance. The two floors of wellness and leisure amenities are separated by an eye-catching spiral staircase.

The Pierre's mansard roof adds a touch of romance to the Upper East Side skyline, and that sense of elegance extends to the interiors. From the painted ceilings to the bifurcated staircase, no detail was overlooked in the entrance lobby that sets the tone for the interiors and amenities.

When the Level Club of the Masonic Order was converted to a residential condominium in the 1980s, one-of-a-kind details from the original lobby were kept intact. These include grand staircases leading to a balcony overlooking the historic space.

The Robert A.M. Stern-designed 20 East End Avenue brings prewar-inspired elegance to a tranquil yet buzzy Upper East Side neighborhood. In the octagonal attended lobby, a grand architectural staircase leads to the building's three-story amenity suite.
