Hi Grasswind,

Sorry for the late response.

Even if using blocks for an aircrete dome home, you are still building it in the shape of a dome and also adding an exterior fabric afterwards which acts like a rib cage bringing it all together in terms of structural integrity. I have built one of these and was amazed at how strong and solid structure was. But it looks like can also do a form build that would cut down construction time. But you are then adding cost into buying the form of course...

Check out what this guy did using an airform

and I also recommend you visit Alosha's progress on his dome home project

Yes would need to be out of the city for sure in USA or Canada so as not to get by-lawed to death...

Best of luck!
