yeah,the good'ol rounded roofs - just try and try again. it takes some time and some testing to get such roof done. but every attempt will bring you a bit closer

my first rounded hut had a fireplace in the center with a roofed chimney

after that i returned to my round houses to learn if i could find some optimization
