The group at Konbit Shelter has made phenomenal progress on their triple dome in Haiti. Be sure to check out their blog for full details and, if at all possible, it would be great if you could find a way to support their project.
Konbit Shelter in Haiti Nears Completion
From what I gathered, this construction cost around $30,000 to build although the travelers were volunteers who came to help the locals. I like this model and would like to enlist some help from this group, but I can’t cough off that amount or go on debt to build it.
You could start with a small, simple dome to learn the basic skills. Build larger structures once you have a trained workforce. Everything you need is on our websites for free.
