How Do I Get Rid of Grass Area For Basement level?

Go to the basement and click on the room to highlight it. Then page back up to the floor above it. There should be a yellow outline on the roof of the basement where the grass is. Click on it and it should give you the option to get rid of it.

Yes I get rid of the ceiling, but inside the house you see just a grass patch where the staircase will go. And even if you wanted the staircase area completely free, there is still a grass patch that ruins the look.

Basements are way screwed up since terrain manipulation tools came along. ? I built a basement under a house Several months ago and it caused this weird slope thing up one side of the house that I could not fix no matter what I tried so I ended up bulldozing the entire house. I personally rue the day those tools were added. I haven’t bothered to try basements since.

I noticed that too and I hate it.
