MadisonDawn99 Ok. Just to make sure that you are hitting the correct icon to change floors, it is the middle one shown in this pic.
It looks like two triangles. One pointed up and the other pointed down. You click on the upper one to go up a floor, and the lower one to go down a floor. If there are no floors above the current level, then the arrow will be greyed out. Same for floors below the current level. Sometimes you might have to move the camera with the mouse to see another floor.
Before you start the game next, run a repair. That is done in the EA App without the game running. Just click on the "The Sims 4". Then when you get the popup where you hit play, hit the Manage button. Then hit Repair and let it run. Once it says it's done, open your Documents folder, then Electronic Arts, then The Sims 4. Delete the localthumbcache.package file. Close the windows and go back to the App and start the game.
I doubt that remaking the household will do you any good.
If none of the above works for you to be able to view all floors, then come back and we can go from there.
Hope this helps.
