Already had the sill plate around the perimeter of the house replaced sitting on the field stone. But this part just confuses me.
First few photos are taken from the perspective of my covered porch:
a cavity in the wall of my covered porch that bridges the original house/dining toom (on the left), the living room that is an addition that connects my original house to the garage (to the right), the addition that bridges a second story addition and the lofted area above my living room that connects to my garage (above), and my crawlspace (below)..
There was a fire like seventy years ago about. No records that spell out any remediation done.
Most of the charred wood is solid beneath the char. The rotten floor joist I can see from in the where all the horizontal stuff in that wall cavity seems to sit, sits on a field stone wall and is mortise/tenon jointed to a opposite direction beam.
One pic is from a recent renovation where I had the house taken down to the framing.
Idk if it's possible one of these additions/structures is taking some of the load off of those parts of my framing. A bit too broke ATM to afford a structural engineer. Pics at the end are from the attic. Last pics are from the basement.
