- I think stairs may be one of the most
- Emotionally malleable physical elements that an architect has to work with.
- At its most basic, a stair is a way to get from point A to point B at different elevations.
- Stairs have a common language.
- Treads, which is the thing that you walk on.
- Riser, which is the vertical element that separates the two treads.
- A lot of stairs have nosings that create a kind of edge.
- And then the connective piece is a stringer.
- Those pieces in different forms make up all stairs.
- I assume stairs came to be from the first time someone said,
- I want to get to this higher rock from the lower rock.
- People climbed using whatever was available, stepped logs,
- Ladders, and natural pathways that were worn over time.
- Some of the earliest staircases, like the pyramids in Chichen Itza or the roads to Mount Tai in China,
- Were a means of getting to a higher elevation
- Where people sought for worship or for protection.
- As engineering has evolved, so has what's practical.
- Stairs can be made from all kinds of material,
- There are linear stairs, there are spiraled stairs.
- Stairs can be indoors, they can be outdoors.
- They clearly help us in an emergency,
- But they're also a form of art in and of themselves.
- As we move across a stairway,
- The form dictates our pacing, our feeling,
- Our safety, and our relationship and engagement with the space around us.
- So for a second, think about stepping down a gradual,
- Monumental staircase, like the one in front of the New York Public Library.
- From those steps, you have a view of the street and
- All the people around you, and your walk is slow and steady
- Because the tread is so wide.
- That's a totally different experience than going down the narrow staircase to,
- Say, an old pub, where you spill into the room.
- There you encounter tall risers, so you move more quickly.
- Stairs add enormous drama.
- Think about how stairs signal the grand entrance
- And were the star of that moment.
- Stairs can even be heroic. The staircase that remained standing
- After September 11th and the attack on the World Trade Center was dubbed the Survivor Staircase
- Because it played such a central role in leading hundreds of people to safety.
- But small stairs can have a huge impact too.
- The stoop is a place that invites neighbors to gather,
- Blast music, and watch the city in motion.
- Fascinating to me that you see people wanting to hang out on the stairs.
- I think they feel a deeply
- Human need we have to inhabit a space
- More than just on the ground plane.
- And so if you're able to sit
- Halfway up there, you're in a kind of magical place.
