Same here, we tried to figure out how old our house was once and the furthest back we got was 1850. The house existed before that for sure but that's the oldest bit of paperwork we could dig up for it.
Oh yeah that's a good idea! I want to check with a nearby estate too because it used to be part of that, 1850 was just when it separated and became an independent property.
Stone? We had only unburned bricks, no right angles, several kinds of walls put together and bulging out to rooms. It is always funny to add or redo some furniture, electric work ...
The outside walls are stone, but inside it's a big mess: I never know what color the dust will be when I drill a hole.
And I can't even imagine right angles or straight walls. It must be so handy.
Funniest part of it is that for some parts even exists some drawings, some electric work was made by students (friend was teaching electricians), something done by friends...
My workplaces is like this:
Some walls are red brick, others white/yellow brick. I have one random concrete wall. A couple plywood walls. I have yet to find a plasterboard wall.
