Hello,
When Moz I & first moved back to my folks place a few years ago, we needed a place to drop our shipping container of personal effects.
I traded the demurrage with my father for putting down a small wall and some concrete pavers that would eventually wrap around into a leant to.. A semi subterranean round leant to.. which I will put pics up of later.
Ended up getting just under 100m2 of 60mm concrete pavers and about 500 besser blocks.
