Y staircase

I don't think you can... at least not on one level of the house.

there are some YouTube videos showing how to make “L” shaped staircases with the new foundation tools. You can probably modify those tips to make a “Y” staircase.

I’d share a link but I haven’t posted enough on here to be able to do that..... Anyways share pics if it works out.

So with the new stairs tool, can you now make y stairs?

T Shaped stairs, yes. But the patch isn't available for consoles yet.
