Not heating a building during the winter makes such a huge difference. All that water damage is leaking into the walls and washing away the 103 year old mortar holding the bricks together.

If the water damage is contained or at the very least negated, you might get some more years out of that place.

Fox is right - pidgeon shit + dust...avian flu anyone?

Not to mention the concrete mix design for an internal slab where you are not going to have freezing and thawing vs a slab that will are vastly different. The concrete could fail under those conditions.
