K9DB's Teleporter and Elevators mod lets you make aesthetic stairs into functioning stairs. Like say you line up selves around a pole to look like a spiraling staircase place the red marker on the first floor at the base of the staircase and the green marker on the next floor. More green markers can be placed if the staircase spans multiple floors. Mod requires city living though cus it uses the elevators in the pack and you can only really have one stair case made with this cus only one red marker can be placed
