Hi,
I'm shortly going to be ripping down two crappy old rotten sheds, and replacing them with a 10' x 13' metal one. The base is patio-type slabs in concrete; I don't know what's underneath but it's build up 8 or ten inches above the grass so it's fairly substantial. The surveyor when I bought the house described it as "sound", while also picking holes in lots of other things, so I think it's ok. The shed has no floor, and will fastened directly to the base.
This all seemed fine, but having read some other posts here I'm wondering if there's likely to be a problem of damp and condensation. It seems unlikely that the base would include a damp course. I don't need the shed to feel like my front room, but I do intend to store quite a lot of stuff down there (I don't have a garage, and the loft hatch is very small) and I wouldn't want it to be damaged by damp.
Do you think I'm likely to have problems? If so, what can I do about it, either when building the shed or if I find I have a problem later. I don't want to spend more than I have to - I wasn't planning to replace the sheds at all for a while, but I've just discovered quite how rotten they are and it won't really wait.
