Also, I often download houses with unusual features (odd elevations, driveways on a slope) that I don't know how to do. But - almost always- I wind up deleting them because of routing and playability issues.

@grammapat-It sounds like you should start doing your own builds from scratch in a BACC style game and it will get easlier over time since the early builds in a BACC style game are supposed to be simple and boxy like mine in Dodge are since it's only just starting to form into a small rural farming town.Strting a town from scratch and building it from the ground up means that building simple in the early stages is fine and it looks like the sims built it.That's why I pretend to be bad at building in a new game with a new town.It's to make it more like the town is growing up slowly over time and it's what's going to happen in my Pleasantview Epic Challenge which is starting out with the turn of the 17th century.
