What concerns should I address? How do I avoid killing myself in the process? Should I deal with state/county/city permits? What can I use to reinforce it best without overdoing it? How about water tables? I'm on a hill and I'd hate to see the building pop out of the ground at the first sign of rain.

just wing it and go real slow

Draw out a detailed schematic (measurements and shit)
Go to the city and request a permit
Read about pouring concrete and shit
Have money for more qualified people to do it for you.

Just wing it and go real slow. I'm sure you'll be fine.

Seriously tho, OP, look up Disco Dave's tunnel guide. Pretty basic stuff meant for protesters, but useful.

Get a commercial septic tank, modify and bury it.
Have you considered storage containers?

I actually have a similar situation, there is a small convenience store building that was abandoned after a fire happened there, how do I turn it into my personal man cave and what dangers could await anons?

>tunnel/workshop underground
Why?
What is with the obsession of going underground on /diy/? Its almost on the level of shipping containers.

Like ship containers you mean ?

I want to save on land above, the place is really small to start with, so I need all the space possible, the land is quite expensive too.
More expensive than several hundred cubic meters of concrete and reinforced steel.
Also reduced noise levels (all the neighbors)

Yeah, they're really easy to use for this sort of thing. Just dig your hole, drop em in, cover them with dirt. Strong, safe, simple.

probably the most realistic suggestion so far
not that any of this is truly realistic....workshops need space, air, power

Just dig deep op. It won't collapse or anything. That earth is older than you. It's solid.

Here we go again. Shipping containers strength is all in the frame. The walls and roof are not designed to carry any weight. A better idea would be to use corrugated steel pipe, since that is something that's actually meant to be buried without collapsing.
Just get a 10-12ft diameter pipe. Frame up the floor and any walls you want. Run pipes and conduits for utilities. Finish furnishing the inside however you want. and close up the ends with steel plates, and there you go.
