How would I go about making a 6 meter deep tunnel / hole under my house leading to a secure box in which I can store my valuables? Like in this picture, but without magic. And how would I get them back out?

Have you tried magic?
You really don't know how to make a hole without using magic? As for getting the stuff back out... you'd want some powerful suction machine.

Found one

is this really the average american intelligence.
Would've been cooler if you'd said it was for your wife's son's science project, like they used to back in the day when we had REAL tunneling threads. And 6 meters? Wtf! Go at least 15 meters, with a 10cm diameter hole, or don't even bother us.
>all of that seething over nothing
Don't talk to me or my wife's son ever again.
Explosives.
So an underground box with a vertical tube attached? You toss random valuables in and need a way to get them out? The best bet would be to bury something like a large conical hopper, with the end sealed of course. This way all the valuables naturally fall to the center. I can think of two options for the extraction. You could probably stick a tube auger down the access pipe. This will likely damage the goods though. The second possibility would be to put each valuable item in its own tiny steel case, then pull it out with a magnet on a string.
Take the tunnel pill
probably with a shovel or some other kind of digging device
Bring in some isekai slaves to dig it out for you, then dispose of them, no one will ever know. Maybe leave one of them in the box to throw items back up when you need them.
