Patti Stouter’s New Earthbag Building Slide Series
“A how-to slide show series. A picture is worth a thousand words. And many natural builders have limited access to the internet. These slide shows will speed information transfer into many languages because they are mostly visual and come in small and large formats. Slide sets are also available in French.”
Structural aspects
Practical Action
“Practical Action works alongside communities to find practical solutions to the poverty they face. We see technology as a vital contributor to people’s livelihoods. Our definition of technology includes physical infrastructure, machinery and equipment, knowledge and skills and the capacity to organise and use all of these.

A Cautionary Tale
Sometimes people send us emails asking specific questions about their personal projects, and we usually try to help them as best we can. Not long ago we got the following email with several photos attached:
I came up with the idea of building my own dome here in south Morocco where I live. I got some refurbished polypropylene bags and decided to do a 5m diameter dome to provide a shelter for horse food and equipment.
I decided to use the soil from our garden which is very close to sea sand. Since this was an unstabilized soil, I decided to tie the bags very firmly at the top to prevent any sand from slipping out, and also damped the sand so it could be tamped better. I dug a trench down to half a meter that I leveled with double bags filled up with small rocks, and then started the courses of bags, with two barbed wire between each course. We went up to half a meter straight, and then started to corbel the bags inwards. We have been working for two weeks now in a team of four, and it’s getting quite high. I wasn’t planning on doing a loft, since there would be no use of it for me. I’m getting a bit worried as we are working at higher levels that the whole thing might collapse, so I thought I should give it a try asking your advice. It feels quite strong while working on it, but when tamping, you can really feel the strikes wherever you are placed up on the wall.
Traditional Post and Beam Barn Home Kits
“Pole barn dwellings are much different than post and beam barn homes. The only similarity between a pole barn and a post and beam barn is that they both have upright posts that support the frame of the barn.
Roundwood Open Web Joists
Inspired by projects such as William Castle’s house, featured on our blog yesterday, I set out to design an open web joist using small diameter poles for non-code areas. It’s not as shiny and elegant as manufactured brands, but hey, who can argue with the cost? These trusses would cost just a few dollars apiece if you have a good source of poles. In parts of the U.S., and probably other countries, the poles you would need are practically free. Small trees like this are thinned out to reduce fires and help larger trees reach marketable size. You could use scrap metal for tie plates and cut the cost in half. Barter for a can of screws and you’re talking really dirt cheap.
