Foundations for my new shed

Our 14x5 brooder shed had shingle with weed suppresant underneath.  It never rotted or had any nasty little rodents underneath it.

The good thing about that was that if the ground wasn't quite level, a little jiggle around with the shed soon levelled it up.

Concrete isn't necessary.  Brian has used 3x3 and 4x4 wooden posts underneath before, shouldn't have any sagging as long as the posts are reasonably close together.  About 2ft apart, maybe a little more.

Oh, and my 7x7ft chicken house was stood on top of 4 pallets that kept it off the ground, another idea maybe?

I don't know about your allotment rules, but ours won't let us put down concrete.

Anyway, depending on the physical size of the shed, I would suggest a few solid concrete blocks bedded into the ground, with wooden beams across the top of them to support the floor-loading of the shed. It needs to have air circulating around it, which stops it from rotting.

Andy what is your shed constructed of.
Ours is sheet metal and does not have a floor.
Was advise to put it on a 100mm concrete base as you say, so just leveled the ground, a layer of sand and the a double layer of 50mm concrete slabs with a heavy plastic sheet between the slabs to stop damp raising.

Sit it on four concrete fence posts laid down. They'll never rot.

Loved that video!  They make it look so easy,  I have a struggle just hammering a nail in straight.
