Shed base

[Jake2021]

Hi I’m just about to start to lay my base for my shed/summer house thing anyway I need to raise the ground for the base by 30cm. What options do I have to keep my sub base in without collapsing at the sides. Concrete base is out.
Thanks
Jake

Why can’t you lay a concrete base ?

I’d love to lay a concrete base however the shed is 15 square metres which is fine but to access the rear garden as we are a terraced we have to go through seceral
Gardens to get to ours which means me with a barrow and doing all the mixing just wouldn’t work
