Shed Base on Clay Soil

[Mac22]

Hi,

First post here any help greatly appreciated.

I am installing a fairly basic 6x4' garden shed. I really don't want to go with concrete base, but I see a lot of conflicting information about what can/should be done. A bit more info:

- Nothing heavier that lawnmower being stored
- current ground is old top soil for first 6-8 inches, then clay soil below that

What I was considering:
- Dig down maybe 4 inches and frame and fill with hardcore/stones and compact
- Add membrane and construct plastic modular shed base
- Shed on top

Questions:
- Do able?
- Does the clay soil change any requirements? (Its very heavy soil)
- Can I cheap out and use old stones from my driveway instead of hardcore? or will the whole thing burst into flames?


Any help greatly appreciated.

Why dont you want to go with a concrete base?

Firstly, not something I've done before. Secondly, Im not confident that in 6 months I wont want to change the location of the shed!

I'd imagine your solution is fine.

Actually in process of digging a shed base myself but I want 12x10 and I'm likely to be using paving slabs on top of a hardcore base.

I have flip flopped between everything from a storage box to a 12x10 shed/summerhouse. I have had two sheds previously, which I didn't install, both on slabs and both times the slabs eventually became uneven. Obviously if done correctly that may not be the case, but I've lost confidence in them to be honest. Have settled on a plastic modular base I think

Dig down to clay on the corners, then slab concrete blocks on top of clay sit shed on top.

So only 4 points of contact for the shed floor?
