Such an amazing project even though you are being rushed into it and boulders have been working against you.
We are in the process of buying land and I always dreamed of living in a dome shaped house too though cob houses are apparently not a good thing in the tropics as many critters like termites like to make their home in the straw. We are thinking of the adobe earth bags for construction.
Good luck and I am looking forward to reading more about your progress. Good luck 💚
