groundworks for shed

[wa209]

Hi to all...well the last few weeks i have levelled the garden and taken out two skips load of rubbish to the point where its now empty.
My question is regarding the 'base' for a large shed. I have compacted the ground and added stones and then sharp sand over the top. Pretty solid and firm.
I was going to use paving slabs..but having to level each to others would be driving me mad...
2nd concrete slab...don't really like the idea of a big slab of concrete...don't know why
I had a thought about concrete lintels that the bearers would rest on..they it turn resting on the compacted soil and sharp sand...
Anyone offer advice re this ...shed is 24' x 10 out of 15mm t&g .

thanks all
