Which one of the following do you want in a future update or patch?

I just want spiral staircases because I can never fit the regular ones in small houses. When my Sims family grows I always have to purchase a whole new house for them instead of just adding a room upstairs because there is no room for the staircases.
I can't build (and I don't even like to try) well enough to change the house just to fit the staircases in, so spiral staircases would be a huge help for me.
