Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Is it possible to make multistory buildings?

You can't physically stack them since the AI-Grid which is used for pathfanding is 2D. Likewise you can never walk beneath a bridge and on top of it the same time.

That's why there are always clickable stairs in the game that lead to another level of a building. In the editor you need to teleport to another location.
