Ive decided to only have one main set of stairs, and I feel like because they are the only set they need to be obvious and draw people in. So I researched some types of stairs and I found some that I liked at this website: http://www.toxel.com/inspiration/2008/11/22/unusual-and-creative-staircase-designs/
 it actually has some interesting stairs for other purposes too. The stairs that I like are the ones with glass on the outside so as you can see in. I think this can be adapted to my design so that there is glass showing where the stairs are from both sides of the building.
