I also really like the simplicity of the design. Stairs are always tricky and seem to take up some much space no matter how you figure them. These stairs themselves are cut from sheets of metal while the pole (also metal) serves as the handrail. That is just genius. You can see that as you walk up or down you can always have a hand on the pole.
It may not be the most conventional approach or solution, but it works. They solved the issue and completely transformed the two spaces.
