I'm designing a house with a half basement . The other half of the foundation needs a 3' stem wall (to get the footing below frost line). The 'slab with footing ' tool won't let me add a stem wall and the foundation wall tool always puts the concrete floor down on the footing and adds a floor on top, creating a crawlspace.
I need to create two foundation areas, with their tops at the same elevation, and, backfill the shallower one to pour a 4" slab. The shop side of the house will look like a slab on grade.
Any ideas??
P.S. Is there anyone who can point me in the right direction for a tutorial on doing split levels within the same storey?
