I have been thinking about the 3 ways that a person may draw the slab on grade for the vignette, which of the 3 samples that i have drawn would be an acceptable solution?
Secondly, do you have to break each element? (i.e. ceilings at fire wall & interior wall) or can they cross?
and lastly, do the rafters have to overlap into the bearing walls? or just butt into them?
