I wonder if anyone knows of a price comparison between building a wofati vs building an earthbag structure, especially on relatively flat land.
Earthbag is supposed to be really cheap--just the cost of excavating and the sandbags, which are supposed to be cheap. People usually say something like $400 to build one. And, it seems a lot simpler than wofati. My husband and I aren't good at building stuff, and staking earthbags seems really simply. I don't like the idea of using so much plastic, though.
We're in the foothills outside Seattle. I tried finding out what our ground temperature is here, but all I get is people talking about how high the ground got in our heatwave. Maybe I'm not telling Google the right words?
I'm not sure if it's better to dig down deep into the earth, or to only dig down a little and cover with earth like a wofati. We get a lot of rain here, and the place we're thinking of building the cellar is on a hill and drier than other places....but it could still have water issues.
These people made an earthbag cellar up in Alaska, digging straight down into flat ground to make it. The water level was 10 feet down when they dug, and in the spring it rose to 3 feet. Their cellar flooded. They explain what happened at around 9 minutes into it. The cellar was only 1 year old when they filled it in!
I don't know if it would be better to just excavate down 3-4 feet, and then mound earth up. My husband wants to go down deep, but I'm afraid that would cause the walls to cave in.
I tried to get pictures of the area, but there's lots of salmon berries and ferns in the way. It's shaded under a bunch of trees and facing north.
