Shed Base Suggestions

Hello all,

So after demolishing the concrete post, I've been looking into shed bases. What I already have is some flat concrete at the back, then these paving slabs which are not particularly level, but not as bad as the awful 'crazy paving' in the rest of the garden. It looks as though there was a shed over both the concrete and the paving slabs at some point.

The shed I want is either going to be 10x7 or 13x7 depends what I can get away with. Could I take the slabs up, put some sand down or flatten what is already there, and put the slabs back down to get it level?

I would make your own wooden base using 45x90mm tanalised wood for framing and set it directly onto the existing flags. You can get some metal L legs to level it as required. This is the basis of those portabase kits you see, but way cheaper to do it yourself.

I wouldn't set wood directly on them nor would I rip them up.

Get some adjustable shed legs/feet. Build a base frame on top of those, make sure it's level and put the shed on top.

I opted for concrete breeze blocks with damp proof course attached to the top of each block to avoid moisture rising through the concrete. Quick and easy for what I needed and still proving successful after a few years now.

I'm going to go with the wooden base option, there happens to be a timber place down the road from me so I can get the stuff from there.

So I would need 2x13', how many 7'ers? One per foot?
Should I also put flat panels on top of this in addition to the shed floor panels?

Timber will rot eventually with rain water etc if set directly in contact. If it saturates the water will go upwards.

I also would not go wood. Last shed I put down was on patio slabs, the one before that a concrete base.

In your situation I'd probably smash up the slabs in place, make a wooden frame to contain concrete which you could pour on top of the broken slabs and level.

To do it properly the whole lot needs to come up. Those slabs are not level and have not been done properly.
