It sounds as though wet timber is at the root of your problem.
If you can, leave the building with the doors (and windows, if fitted) wide open for as long as possible over the rest of the summer. Hopefully, you won't experience excessive shrinkage.
Once the timber is fully dried out, treat the exterior with a solvent-based preservative such as Cuprinol or Ronseal. These days, you'll only find this at a proper builders' merchant - DIY stores only sell the useless water-based equivalent.
I would seal the concrete floor, but again, give it a few weeks to dry properly.
If you have a timber roof, that should be fine. If it's made from something like corrugated steel or plastic, I'd consider lining it with plywood.
Hope this helps!
