I live in Nova Scotia and looking to build a cob home in the valley area. I have done lots of research on different building options underground home, c-cans among others but cob building for right now makes the most sense for me. The only thing I have found it hard to find information on is building a second story with cob. Should I frame it? Can a horizontal slab creating the second story support itself? Should I build support beams? I have heard that tapering the walls is helpful.
I would just like information on the best way to go about constructing the second story and any considerations I should have.
