I have a project where the building is on a slope (one level building) so
there is a varying height of below and above grade exterior wall area. I
have a few ideas on how to do this, but thought I'd throw it out to the
group hoping someone has done this and would want to share their method.
Not only is it sloping, but then on the uphill side there is a cutaway so
there is an entrance with windows. I am thinking of making multiple shells
with each touching, and break it into a couple of different areas with the
equivalent amount of above and below grade, and just making it a horizontal
division (above and below shell). It seems like I'll need at least 5 shells
to split it into 3 areas, one with fully above grade walls, then two
partially below grade and each of those will need two shells stacked (one
above and one below). Maybe I can do it even simpler with just two shells
stacked with the equivalent amount of above grade in the top shell and
equivalent below grade in the bottom. This doesn't seem too convoluted, and
hopefully it isn't or there is a better way.

Thanks
