"Stoop" style porches

[BB boy]

Go to build floor>foundation>derive foundation from first floor> then add the info on how thick you want it or how high the foundation wall will be. You may have to come back and open the foundation plan, then turn on reference display and add the (foundation) wall under the stoop section, you will need to set the floor height for the stoop (which is actually a porch in the room defintion). Open materials, select what material / color it is to be and you should have it. Hope this helps
