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

That photo was just to give an idea,they would be 16ft high by around 20ft wide,
Steel ring`s were available in 6 and 8ft span`s,held together by tie bar`s 3ft apart,and like the photo steel sheeted behind,
And to fullfill the HSE,one would set up a pair and partly sheet,and advancing debris would be throw behind making room for another set to be erected.
One could always brick arch between the ring`s as often was the case in older Collieries.

55gal oil drums with a lengthways cut and the ends cut out so as the next one will slide through the last one are more my sort of scale

On that theme,go a little larger,steel cylindrical tank`s used as the entrance to Collieries in the FOD.

that might also serve for jema's bunker if the local scrappers have anything suitable

Why not just bolt together a frame out of three by threes and two by four, screw planks to it, cover with waterproof membrane and put the topsoil back on top?

having built grub huts and such like it takes a lot,i do mean a lot,of timber to support wet earth .
all soils get denser when wet but when it rains some soils are extremely dense and will crush all but the most sturdy roofs.i know this cos i was under one in the middle of the night when it went from dry leaf litter and a bit of soil to several tons of creaking squelch and then tried to kill me,i managed to grab a 3 legged log stool as an emergency pit prop and then crawled from the wreckage.the dog moved out for a few days.
and it is still timber in a hole so rot will be a problem.
another though re the "box" is to use a section of large pipe should one be available.

Perhaps start at the other end - what and how much of it will you store in the space? Perhaps begin with a non-working refrigerator buried on its back with the door upward, at ground level. Store things for a season, decide how it works for you, and then think about building a larger version.
Consider also making a clamp: https://en.wikipedia.org/wiki/Storage_clamp and http://www.organic-gardening-and-homesteading.com/storing-root-vegetables.html
