Half-Circle building

[=M$= Oroberus]

Hey, pretty new and was wondering if there's a practical way to build a roof for a half circle building. Was planning to make a smithy in that style but as it's only a half circle, the roofs are very messed up when meeting in the middle, any tips?

You want to build half a yurt basically. Put normal walls in a half circle. Then put 45 degree roofs on top, then put 26 degree roof on top of the 45 degree roofs. The very center will have a small hole. Build a mini roof on top of it. You can add me on steam if you want me to show you.
