I too prefer the traditional mongolian, but, being ever further from Mongolia I will make do here in the NW US. Much of my planing comes from Paul Kings book, and a website in Europe, SimplyDifferently.org: Home
he has a calculator on there that allows quick dimensions given others. Its been a big help to me in planning mine.
Mine is/will be 24' in dia, traditional, but, with two conventional windows, 6 khanas in all but 2 by 4 rafters and a dome
with hardened glass, plus a stove pipe replacing one pane.
I will be back looking at your posting here often. I love the painting and will do the same, red on the rafters and the door. Probably on the lathes too. I am pricing wool carpet padding to go under the cover, and tyvek will be over it and under the outer cover. Like you folks I will use better commercial covering then what has been used often.
Thanks for posting your beauties.
