I am building a porch on my house. It will fit in to the "L" shaped area as seen in the pics. The size is 6 x 14 feet. I'm in Illinois, so we get hard freezes.
My question is, would it be better for me to bolt 2 x 6 boards to the foundation walls using anchor bolts and build out from there, or should I build it on 6 posts like a 6-legged table, unattached to the house? If I bolt the boards to the house the outer edges of the porch would be supported on posts. I've already poured two footings, as you can see in the pictures.
It seems to me that drilling into the foundation could cause cracks or some other problems. OTOH building it on 6 legs would be more work and expense.
Any words of wisdom?
