  1. I think stairs may be one of the most emotionally malleable physical elements that an architect has to work with.
  2. At its most basic,
  3. a stair is a way to get from point A to point B at different elevations.
  4. Stairs have a common language.
  5. Treads, which is the thing that you walk on.
  6. riser, which is the vertical element that separates the two treads.
  7. A lot of stairs have nosings that create a kind of edge.
  8. And then the connective piece is a stringer.
  9. Those pieces in different forms make up all stairs.
  10. I assume stairs came to be from the first time someone said,
  11. I want to get to this higher rock from the lower rock.
  12. People climbed using whatever was available, stepped logs,
  13. ladders, and natural pathways that were worn over time.
  14. Some of the earliest staircases,
  15. like the pyramids in Chichen Itza or the roads to Mount Tai in China,
  16. were a means of getting to a higher elevation that people sought for worship or for protection.
  17. As engineering has evolved, so has what's practical.
  18. Stairs can be made from all kinds of material,
  19. There are linear stairs, there are spiraled stairs.
  20. Stairs can be indoors, they can be outdoors.
  21. They clearly help us in an emergency,
  22. but they're also a form of art in and of themselves.
  23. As we move across a stairway, the form dictates our pacing, our feeling,
  24. our safety, and our relationship and engagement with the space around us.
  25. So for a second, think about stepping down a gradual,
  26. monumental staircase, like the one in front of the New York Public Library.
  27. From those steps, you have a view of the street and all the people around you,
  28. and your walk is slow and steady because the tread is so wide.
  29. That's a totally different experience than going down the narrow staircase to,
  30. say, an old pub, where you spill into the room.
  31. There you encounter tall risers, so you move more quickly.
  32. Stairs add enormous drama.
  33. Think about how stairs signal the grand entrance and were the star of that moment.
  34. Stairs can even be heroic.
  35. 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.
  36. But small stairs can have a huge impact too.
  37. The stoop is a place that invites neighbors to gather,
  38. blast music, and watch the city in motion.
  39. Fascinating to me that you see people wanting to hang out on the stairs.
  40. I think they feel a deeply human need we have to inhabit a space more than just on the ground plane.
  41. And so if you're able to sit halfway up there, you're in a kind of magical place.
