Are there spiral stairs in the sims 4?

I've made some grand staircases in TS4, but they do need multiple floor levels to get the feel right. In some houses I've put stairs up to the attic - even though nothing is up there, just to get the grand staircase look. Something a bit more interesting to just join two floors would be great. I also wish it was easier to delete single floor tiles to have a bigger opening in the floor around the stairs. Stairs can also be difficult to place when you've made a hole in the floor you want them to sit in.
