If I had my land in the countryside, just as I have wanted to have it for a long time,
but a long time has passed and I don't have it, I would have a tool house,
and inside that house, I would build a well about 30 meters deep
to take water for general use,
but at the height of about 10, 15 meters, I would make a secret door,
that horizontally would take me to a secret room, an emergency exit
that would lead to another seriously necessary point,
and there I would keep my keys... but there would be another secret place there,
...
You might want to know that Carbon-Oxides and Nitrogen are heavier gases, sinking to the bottom of hollow spaces. So dangerous gases can build up over time (a known problem with wells) from the bottom up. Quite some people that fell into wells passed out and suffocated. As nice this idea is, without proper ventilation, the secret room, or the way to this secret room could become quite dangerous for yourself.
Yes, you're right, it's need exhaust fans, but for the place to remain discreet,
you can unblock the exhaust pipe from the secret room, to the entrance of the well.
and in the same way, an air intake in the room, it is ideal that this intake
would come from another place..
And sometimes, it is not necessary to wait for a while for gases to form,
because as soon as in some places, after digging, gases are already found.
Where I live, the people who dig wells, do tests, putting a cloth lit with fire, tied.with wire to the end of a rope, and if when they reach the bottom of the well and go out, it is because it contains gases that leave the place without oxygen and then the fire goes out due to the lack, and in other places, the gas turns on and does not go out...
Yes, I know that there are several gas meters in environments, which should be used, instead of risking an accident when you set fire to see if there are gases...
follow some videos for example:
This one, with more than 20 meters, lacked air, so it has gas | In this video, with eleven meters, the guy abandoned because of gas, and this guy was called who is explaining about the gas... and it's already 20 meters long ...explaining | This one apparently has, and if it does, it always will, so in this case, it will need a more efficient air exchange system in the 'S.room'
 | Test with fire, ok.
| this one lit up and never went out:
I don't know why, but this video looks like these stones.. But there are several serious videos of a lot of gas coming out along with the water or with methane measurements much higher than normal |
Before digging a well there are already risks, and after it is ready,
and still making an arm in the middle of the way,
there will be even more risks, and the risks are diverse.
-And these old tests of using fire, only work when digging.

There is also a very sad and funny case at the same time, a 71-year-old man,
jan, 2024..dreamed that there was gold under his house,
he dug a hole of 40 meters in the kitchen, with your neighbor helping you,
and when he came out he slipped and fell, the firefighters were called
to the rescue and there was no gold,...
dug his own grave hehehe...
I don't know if this neighbor is innocent... maybe the old man found the gold,
gave it to him and he pushed the old man into the hole... I don't know

and there are many of them,
collapses, suffocation/gas poisoning, sudden falls....

#:* 'Has gas', is a cheap way of saying that there is something wrong with the air,
and the reasons can vary.
