How many levels of basement are possible now

The biggest house I ever made was for a vampire in FH who was "making" his "children" and so he had a house that was 3 floors up and 4 floors down. I would never make a house like this for normal sims as zipping around as mist wasn't that big of a deal. It has 7 bedrooms and a small bathroom with sink and shower on every floor. Definitely different. :D

Hmmm -- I could make one of those big houses for my spellcaster couple since they both have Teleportalate (or whatever that spell is called).

@S3bSter As for the camera angle issues. I've been using both the Sims4 and Sims3 cameras regularly now. Sims3 cam more on build mode. One tip I'd like to add, if you are having problems with the angles, above levels or underground, the 'top-view' angle in the camera view menu is really handy! You can have all the walls 'up' and still move around and place things without anything getting in the way.
