Hesco wall house
Remember gabions? Hesco walls are gabions for the 21st century. They were developed for protection in Iraq or Afghanistan. Basically they are steel mesh boxes with heavy duty fabric. But the cool thing is that they can be used for housing. Perhaps not in the luxurious sense, but what is intended for disaster shelters could be made into something more permanent. They call it the R-house. It has a translucent tent for a roof, to let in light, since there are no windows in this design, which is great for warm climate life.
The walls are 18" thick and filled with local dirt and rocks. With a real roof, they claim it is a 30 year structure. If nothing else, it would make a great garage or workshop.
