Yes, you can get a 5-level split

Spaceship?

Cargo Container? 

Treehouse?

YURT !!!!

@Account Closed , so  two level house, 3 level house,and each of them are easy.  It is how many stories high they are, now if a house has the entrance in between the first and second levels I call that a bi level.  You have steps going up and down to each level as you enter.  A tri level to me is where you enter in the middle level, but there is a half stair going up to one level and a half stair going down to another level.  So the man level is halfway between between each of the other 2 levels.  Those are the only ones I have experience with.

@Account Closed , you should be able to tell by a picture.  They look like a 2 story house with a another level stuck halfway in-between them off the side.  I have been working on one all day lol.  It is right next door to my personal house, a bi level.

I once walked through a 6-level home. It was super interesting, but I'd never be able to sell it once I was done so I passed on it. 

I sure did, @Account Closed . VERY awkward layout for sure.
