Does anyone know anything about gardening?

Interesting. Works in the typical office floor but that has a more solid base than the typical garden. I'd be worried about the 'plots' sinking or tipping.

Surely the void becomes a rodentarium, apart from after Summer thunderstorms when you end up with a pervasive fetid organic soup.

I have those under my shed. It was a temporary solution while I was having the fence done where it used to stand. I put some old skip salvaged pavers down, used plastic things like those with a wooden frame made from joists on top to get the whole thing level then rebuilt a shed on it.

Like I say, temporary, not shifted, been about 4 years now. Only a shed though so not something you’d walk on everyday. Just a few bikes, petrol mower, workbench. Foxes get under there and the vixen leaves her cubs under there while she goes for food so that’s worth considering, they keep the mice and rats out but you’re re essentially building a safe haven for them to rest in.

First instinct is that doesn’t look safe, second is how to finish it because you can’t mortar or do a flush edge/step. It would make a nice home for rats though.

@ColinTheBald I get what you’re saying about Japanese blades but there’s an undeniable pleasure in using nice tools. My garage has two sets of tools, stuff from yonks ago working on site when they’d get lost, pinched or broken and my good shit that stays locked up. I stopped buying Knippex snips pretty quick after repeatedly leaving them in false ceilings.

Long stressful day on Monday dismantling and transporting that greenhouse with my retired arthritic Dad, the only consolation being I’m £1500 up on the deal if bought new.
