I am at wits end. Running in circles now....I,m attempting to have grade near where top of foundation wall at garage (not grasping levels I think). I'm floating..lol. Trying to put a porches on the front. I have walls coming thru the roof at rear...lol. Can't figure out slab to top of wall...in garage,porches etc.
Any help would be thankfully received and humbly applied.
