Sims 4 should have spiral staircases

Spiral staircases might be in my top 5 wishes for this game, but I imagine it will only happen after a major overhaul of everything to do with building curved structures.  In all my frustrated experiments with curves and circles, I can see where the fundamentals for spiral staircases are Definitely Not There Yet.

This is a long time request for the Sims 4 and has been passed to the team, as we learned back on the previous AHQ forum quite some time ago. So hopefully we'll see them included at some point.

Previous Sims versions have had spiral staircases...I think it's now a matter of they don't really want to add them - we're over 100 DLC purchase options and still no spiral staircase?  Likely EA is just putting people off.
