I want to enclose my entry way and eventually have new entry enclosure/porch.
I talked to my towns building inspector and he said I needed to tie in the ventilation to the existing structure. I was trying to visualize how that would work but I don't understand the "why" behind it to fully grasp it.
My current porch consists of a 7-8" slab, the walls around the slap appear to be built upon 4x6's (my first floor rests on 4x6's about 45" OC).
It seems to me that getting the new floor I would add to vent to the old crawl space would not only affect the integrity of the existing structure just a little but it would be a major PITA to cut a hole in the 4x6.
Can anyone offer some insight into this?
Below are pictures with the labels A, B, C, which are to show what is what and where and to hopefully help explain exactly what I need to do.
The picture with the numbers are to represent possible placements of vents or holes to the old crawl space.
