New Yorkers normally hear the word stairs and think walk-up.

There’s a reason that five-floor walk-ups are cheaper — between groceries, strollers and just being tired at the end of the workday — most city dwellers would prefer to live in an elevator building and join a gym for their daily exercise.

But in these three NYC homes, the stairs could actually draw in buyers.

228 W. 21st St., 8

The staircase in this Chelsea duplex leads to a third en-suite bedroom with a large walk-in closet and access to front and back terraces. But it’s the actual stairs that may get buyers’ attention. The contemporary spiral staircase is currently painted red on the outside with black stairs that are a bright contrast to the downstairs' white walls and Eastern White Pine floors.

27 Harrison St.

This Tribeca townhouse offers four levels in 3,700 square feet, plus a large private garden. The three-bedroom, three-bath house has a modern feel that is apparent right away in its open plan kitchen and living room. But the custom staircase anchors this contemporary feel with its design that matches the kitchen's light wood and stainless steel details.

320 W. 80th St.

With five stories and 6,565 square feet of space, this Upper West Side townhouse needs both an elevator and staircase. The six-bedroom, five-and-a-half-bathroom home is in the Elizabethan Renaissance Revival style, and maintains many of its original details. They include eight carved fireplaces, wood paneling, pocket doors, hardwood floors and high beamed ceilings. A entry foyer also showcases the historic 1899 residence, with the original wooden staircase as the centerpiece.
