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

now sitting on crumbling mortar.

Greatest deflection is aout 30mm, over 70 years. The joists are
still nicely in their holes, that was one of the first things I

I will be doing something about it - don't worry. Just getting

trying to understand what possible solutions may exist. I like
to have this information before calling in someone who may or
may not know what they're talking about.
