I'm coming to the professionals. I have been trying to build the house I grew up in and it's a nightmare. The problem is the "ground" floor. The level on the floor you walk in the door on is split: two sets of stairs lead up to a kitchen, dining room, living room area (one leading into the kitchen in the back, the other to the living room from the foyer area). There are also stairs leading up to the top floor. Then, the rest of the "ground" floor has a bathroom, a bedroom/office space, a large open "party" area connected to a walled in patio and a garage attached. Stairs from this side lead to the basement. There are railings separating the levels; you can see into the bottom level because there are no walls there.
I cannot make one level split this way. I have tried every testing cheat there is and still end up with four full levels, not a "split" level with a top floor and a basement. Either that, or the stairs do weird things. Anybody have a suggestion for me. I want my sims in the house I grew up in!
