I think it has a fair way to move before that happens, and would
be pretty obvious that something bad is about to happen. Houses
very rarely spontaneously self destruct without warning.

Please say your not sure. All it can take is some ground movement or a
heavy lorry passing the building, to take any precarious structure over the
edge. Do you know that the joist are still properly seated on their
retainers ? Have the joists moved out of their original position and are
now sitting on crumbling mortar.

A low flying jet from RAF Leuchars, brought down a cottage in the wilds of
the Ayrshire country side. So please, if you can see that the movement is
continuing at a pretty even rate over short periods of time, then have it
looked at properly. We'd all miss you.




If you read up on Eulers slender strut/slender column theory, you might
get a shock. The amount of weight a fully supported wall can take,
versus the amount an already bowed wall can take, are vastly different.
The failure mode is catastrophic. I.e. once beyond a critical point, it
happens in seconds.

Without knowing more about the actual loadings and causes, its not
possible to say how dodgy this all is. That's why you need a structuiral
engineer.
