If the space is filled with expanding foam then that will form the box: the shed is basically just acting as a former.


HL seems to suggest it's not totally mad. This should tell you everything you need to know.

Exactly so. You want a compost powered absorption refrigeration system to make it totally mad.

Look up root cellar links. I've got a book somewhere. Root cellar good. Shed bad. Minidigger games brilliant.

I've no idea about the structural capacity of expanding foam although builders seem to use it with a care free abandon.

Would some form of prefab garage be better?

What structural capacity does it need? it isn't supporting anything nor subject to wind loading.

Is a root cellar what you are after Jema, or do you want a very cold store. The article Jam Lady posted should give you details of the former, but I would look up details of ice houses if the latter. Not sure your initial idea sounds too practical, but we should be able to knock it into shape here if we know what you want.

Without knowing much the details, I'm thinking of slumping. As described it's wide-ish deep trench. How wide, how deep, how stable are the sides? With my H&S hat on I wouldn't want anybody working down an unsupported trench.

It's early days, not even sure I can get quite deep enough for this to work anyway.
Purpose is also a little up for grabs, this is something of an exercise of.

I have a rather big trench.
I can use the removed soil to remodel the garden.
I like the idea of a hobbit hole type structure.

Why not just build a proper hobbit hole and make guests sleep in it when they come and visit?

One of the first sites I visited. Sadly I think my ambitions have to be a lot smaller, and looking at the trench progress today I am getting doubtful I can make this work at all.

ty gwyn might not be far off with that giant anderson shelter with its own train set , perfect for any garden.

a smaller version using corrugated sheet could be just the thing,the stuff arches quite well along the grain .
