Very much accords with my experience of Trade Tested. Bought a kids playhouse once many years ago and never again. Parts missing, other parts the wrong size, bits broken in transit, a roof that bore absolutely no resemblance to the roof instructions, and several long telephone discussions that got me 90% of the way to nowhere.

tukapa1:

I'm dreading the roof now, if that's the most confusing part of the instructions.

Actually I take that back. The bit that confused me was putting up the "I" beam that supports the roof. If you look on the shed gallery on Tradetested there is a close up of one of the ends which is different to how I did it in the end (I put the cross member in between the two parts on the wall).

The roof panels were actually rather easy to put on once they are lifted in place. Just be careful with the self drilling screws on the ends, I mis-screwed one and it chewed a big hole in the roof.

@tukapa1 also, a suggestion if you havent yet put the doors on the front frame, leave this until last. My front panel blew over and the hinges bent slightly so the door dont close flush at the moment. So if the doors arent on, do it last.

In all but the driest climate you will get condensation on the underside of steel roof, even after your concrete matures.

A membrane (e.g. building 'paper') will stop any dripping of condensation into the shed.

Passive ventilation as others have suggested will allow moisture to escape from inside the shed

I found water does get in through gaps under the walls in my shed, pallets starting to rot so i put plastic bags under all the pallets to prevent them sitting in water. Doesn't seem to be too much condensation but the potential for it is there. I did drill into the concrete and anchored the walls down to reduce the chance for water to get in. They don't exactly have great gutters either, wouldn't mind doing something about that too.

Time to find a new industry!

I think I will go for a wooden floor when I put my shed in - I imagine it will allow air to move under the floor and ventilate the shed somewhat.

You can buy rubber barrier stripping to go between the walls and the concrete pad. Bolt the walls down onto it and it will keep the water out. Would be tricky to retrofit though.

A bead of expanding foam prior to siting the walls ? Also fills the under-eave gaps.

Expanding foam can be very messy ...
