[Video] 12.How to build multi floors and draw outside area?

Anyone know how to lower the outside area? I need to design a basement. Half of it must be underground and the other half outside the ground.

I need to be able to expand the layout of the landmass around my home? I need more room to add more rooms but it stops... How to expand the land area to be able to draw more rooms?. I can not add any more rooms as the outside land dimension is limited...please help

How do I create the outside area around the basement level without the outside ground defaulting to the 1st level? Trying to create a basement level that can be accessed by a stairwell from the outside area leading to the basement. Pretty much like the photo I loaded
