The most interesting thing about this product is it has already been designed and fabricated as a home. Some people have converted grain bins into homes by cutting door and window openings, etc. You can even buy plans for grain bin homes. But this is the first company to my knowledge that offers a complete home building kit that’s ready for assembly. This particular model sells for $5,700. It can be easily assembled with a few hand tools, although I would definitely use a cordless drill. And yes, it’s made with steel, an energy intensive material, but the extra environmental toll may be justified, for instance, where hurricanes and tornadoes routinely wreck havoc. Its virtually maintenance free 70-year life span is certainly a big plus. I’m impressed with the double, continuously vented roof that prevents overheating. So this design has some good features going for it. It would benefit from insulation. Some might find it practical as safe, temporary shelter while their permanent home is being built or as a cabin or storage building. I wonder if they sell the roof separately so it can be used on an earthbag roundouse?
Special thanks to Cliff for this tip.
