The following are some impressive images of residential staircases.
Of course I’m more partial towards the one with a slide, but the library stairs offers a great use for storage and an impromptu place to sit and read. The last stair shown, called the Ribbon Stair, has an interesting aesthetic but is missing the one design item in stairs that most locales outside of the U.S. don’t seem to require–the handrail. (It’s not that people outside of the U.S. have better balance than Americans, they just have fewer lawyers than us.)
