Concrete. Other stuff will leak or degrade quickly.

Build wood forms and add rebar right?
Itll be water tight unless it cracks right?

>>2984828
It will fill with water. If I was going to do this.

>Backfill it all
>Plant on top of it

Any other way will eventually fill with water, it's inevitable

Cool thanks

I should of included my reason for building this shelter
I want a mostly sound proof shelter (traffic noises annoy me) that is just a simple hangout and relaxing spot, but i figured if it was in ground it could be budget friendly (i would dig it with my buddied mini excavator on the property)

Okay so maybe a better plan is to build a wood frame shed and maybe instead of buying insulation I can stack dirt around the outside of the walls and hope it soundproofs it good. I would build the overhangs to cover the outside dirt wall so that it never really get wet

>>2984828
You want windows letting natural light in from a minimum of 2 sides. For underground houses like this 3 sides is best.

>>2984851
Really bro? Lol

>>2984971
Please forget that I said that and please answer this , you probabaly work an office job and think women should vote and are probabaly not worth talking to
Is there anything particular to know about building concrete forms or should I just follow whatever google says

Stupid question... but I really don't understand so I must ask...

Why are these always underground? Why add the <<collapse and kill you>> hazard to all of the other problems of construction?

>>2985774
The main reason for fully or even half buried houses are temperature stability. After a certain depth the ground is completely isolated from outside elements. In conjunction with solar placement and proper overhangs, you can warm the house in winter and shade it in summer with very little cost or work.

>>2985774
People who build these things typically seem to have defensive purposes in mind and building in the ground is much easier and more affordable than building an above-ground structure with similar defensive capabilities, and it's also much more discreet.

Top of dwelling must be at least 6' deep to avoid aerial infra-red that most counties are using today.

during trench warfare trench foot was a big issue this is the foot molding on the body, trenches included a irrigation ditch and a sump for the majority of filth to collect making drainage a single shovel job instead of multiple, a california closets move air through thermal siphoning and could help with moisture. there are a couple underground homes in california and the nice ones have hallways the width of a car and huge channels for sunlight, fruit trees and use the dirt to move moisture.

these types of houses always make me cry
just make a buried -A- frame cabin so atleast your in code with inspectors and yes youll still be making a full size house but its themed like a basement apartment in the woods

>>2985950
Yeah, but at least some rando wandering through the woods is less likely to spot it or whatever.

>>2984828
That's a well. Lol...
You need to dig into the side of a hill on the opposite side of the weather. Make sure it slightly slopes.
