Falling over would not be a good thing, lol. How do I or the inspectors know if the foundation is good?!
It's easy with a stone house on a stone foundation. (the whole thing is sort of it's own foundation!). You check for level and plumb first. You look for evidence of repeated repair attempts, cracked, crumbling or broken stones, cracks that run from the ground up to door and window openings.
Then you look at how the floor is supported in the basement. They did it in a lot of ways. In some cases they left pockets for the beams and in some cases the foundation narrowed where the walls started above the ground line leaving a shelf that supports the floor decking. If the beams or supports are obviously shimmed in spots because the structure has sunk around the perimeter but not at the center posts or chimney stack and no longer make contact with the pockets or shelf, that's a clue. If the floors are not level-ish, that's another. Some settling is okay and normal, but settling on one side only or remarkable settling is suspect.
From what I know the original house hasn't been changed all that much. Many of the interior walls are open faced stone, if that makes some sense. The floors are all 'new' but are wood with old barn boards.
It has so much personality.
It is likely that the walls were originally framed in, lathed and plastered if the structure was originally a house and not a barn or utility building. My ex Mother-in-law's house, which she was convinced was a 250 year old home was in fact a 250 year old blacksmith shed, converted in the early 1800's to a dwelling. We checked the town's land records. She was disappointed, but it just made it more cool as far as I was concerned.
I wonder why the floors were replaced? The old wide-pine floors were typically prized and pains were taken to keep them. Of course if the structure was built in 1708 the floor might've been replaced in the 1800's when there was little nostalgia for old homes. The replacement would have been with spruce, fir or oak toungue-and-groove flooring, usually 3-inches wide or thereabouts.
The love for old homes came with the colonial revival at the turn of the 1800 - 1900 century. So some time after that they might've decided to take out the Victorian-era floors and replace them with a more "period" correct floor.
Anyway, it's beautiful.
