This Triple Dome Survival Shelter provides much more space than my first earthbag survival shelter. This 915 sq. ft. shelter is for long term survival for a family. It is earthquake and fire resistant, bullet and nuclear fallout resistant. This earth sheltered design is built above grade to reduce risk of flooding. Features include buried cistern between the domes, plenty of storage space, vaulted entry with bullet resistant cellar door. Let’s hope for the best, but it’s also prudent to be prepared for the worst.
Partial domes? Interesting! I’d not have thought of building a partial corbelled dome up against the side of the full domes (I was thinking more along the lines of a shed type roof), but that is a great idea! It could be a little complicated, practically speaking, building with all those different centers and radii at once (I’m picturing multiple compasses in use simultaneously), but I’m sure it could be worked out.

This got posted at Tiny House Designs (one of my favorite sites) and there’s a great discussion going on.

I really like this design. I’ve generally shied away from corbelled domes for silly aesthetic reasons – basically, I don’t care for the way they look from the outside, so I end up thinking in terms of roundhouses, typically with reciprocal frame roofs (which I like a lot). Because of concerns about the safety of using earthbags in an earth sheltered structure, I had not thought about doing something like this. It seems to me that earth sheltering, though, would be an application in which a dome would excel where a circular vertical wall might not – round is sound, and corbeled domes are round (or at least curved) in two dimensions.
Thanks!

Domes and roundhouses are both ideal for earth sheltering. The advantage of domes is that they can be entirely covered with soil.
Stands to reason. How would you roof the un-domed “corner” areas to ensure that they can withstand the weight of the earth piled up on them?
Thanks,

They’re partial domes.
Here are some good suggestions to consider: http://www.k42an.info/?p=470
