Glass is generally not a material used for staircases.

There are a few reasons why, each more obvious than the last. First, glass can shatter, and while a broken wooden board would offer you a bit of recovery time, a shattered glass stair would have you falling through the stairs and into whatever lies beneath them. Second, glass is, as you might know, transparent. This makes your staircase pretty much unusable for anyone with even a moderate fear of heights.

Well, if it’s stupid, expensive and doesn’t make sense, you know you’re going to find it somewhere in the wealthier nations of the Middle East. This glass staircase in Qatar looks both terrifying and like a total death trap. Would you walk down it?
