It is 22 feet diameter inside.I think it
should be 360 sqft or so. I made form on top and poured
concrete with rebars and build 2nd story on top of it (frame....not that dirt cheap
)
Which is another 450sqft.Thats our bedroom where we all sleep.
I started my additions ,so i should have another 760 sqft.(3beds and bath) of living space which will be post/beam and dirt bag mixed up construction.On the front im building
greenhouse thats attached to the building.
My inside is still bags exposed.Have no pics right now.I will coat the bags with plaster and then have 2x4s around and finish walls with sheetrock.my floor is compacted dirt ,so have to finish that also.
I dig trench 20"deep by 24"wide and filled with gravel and compacted,thats my foundation.
The walls are 22" thick including plaster,im in central idaho(elevation 2000') ,we have moderate winters and it works great so far.
I build this after work and saturdays/sundays ,95% myself......i think i spent 5000 on all material which dirt construction was probably 1500.
I think if I work every day ,long hours it would take me 14days for my 22' dirtbag first floor 8feet high with the foundation.
