A matching wall and floor. I personally find "dead space", such as the ground underneath basements, to be distracting. So I created a black wall and floor to use on such areas. They have no shading—they are solid black.
To apply the floor to a basement, you'll likely need to use the "boolprop constrainfloorelevation false" cheat so that you can turn the ground underneath it into a slope.
