After 6 months, the shed is soaking water up like a sponge resulting in some sort of growth. Firstly they blamed me for insulating the shed, then they said my solid concrete base was the issue, nothing to do with inferior quality wood used on the base. I now have to take it all to pieces, waterproof the base (like they should have done), raise it off the base and reassemble it, all at my expense. DON'T BUY FROM HERE, NOT CHEAP AND NOT FIT FOR PURPOSE!
