Sketch for a low-cost house design for disaster areas/refugee camps. The designed down shelter has been mainly inspired/based on the "straw bale temporary structure" mentioned in the Earthship Volume 3 book by Michael Reynolds (and also on the circular Haiti home (see inhabitat.com/earthquake-resistant-earthships-for-haiti-disaster-relief/ to and the Hurricane Home (see Earthship volume 3) to some extend). It has been made simpler by making it much more like a regular storm shelter (hence completely dug out in the soil rather than earth-bermed). In regions with unstable soil (sandy soil, ...), the walls (earth cliffs) need to be excavated as well and replaced with earth bags filled with sand, compressed earth, ... The design can only be used in reasonably dry soil. Straw bales may be needed in some cases (colder areas) to provide additional insulation. The roof is a plastic plate to provide sufficient light (daylighting). There is no insulation below this roof.
To avoid needing to build below ground level, and to eliminate water problems, a double berm can was used (this is similar to the Hurricane Home. Earthbags were used between the berms and the straw bales to avoid needing to load the straw bales (to mount the roofing).
Perhaps that it might be suitable to use natural rubber (latex) or vulcanised rubber bags to shovel the earth in. This makes it more similar to a regular earthship and more earthquake resistant. Also, rubber doesn't degrade easily (atleast far less than natural textile).
Regarding the material of the bags: obviously this should be a natural material, as the idea is to build a 100% natural house. If vulcanised rubber isn't available, natural rubber can be used and or vulcanised on-site (I assume this is done with non-artificial products). You also found a variant of the building on the right. It uses no bags at all but simply a plywood board (on pressed against both berms). I got the idea from regular rammed earth construction (see http://www.iagram.com/rammedearth.jpg )
