I recently came across the Air-Crete dome home while looking at natural building methods on YouTube. This video got me very interested
There is a group called Domegaia that offers workshops and tools to build the domes, domegaia.com. There is a forum on the site, unfortunately the community is not very big yet. I would like to get a discussion going to bring together thoughts, methods, pros and cons and general information on air-Crete. This appears to be a very promising form of low cost, low impact building. That being said there are so many people more knowledgeable than I about natural building so I would love to know more!
