This is exactly, what came to my mind after adoring the beautiful first and following pictures. The whole setup looks very adorable, with the plants inside the bedroom area and i guess it could be very plesant to stay there for holiday.
But i guess the winters will be horribly cold without anything that could be called decent insulation.
And the whole weight of the roof (and maybe snow) is on that little wooden fence. And its better not going to get windy, because as as you can see in https://i.imgur.com/i3o9MBj.mp4 the bars are mostly just hooked into the top of the fence. As someone who learned basic structural engineering, this is giving me shivers. The roof can hold itself pretty nicely like an archway,... but if you get lots and lots of wind from the side, my guts say that it might evolve into a big problem.
They are using a wood burning stove which will adequately heat the space. Instead of controlling for a constant temperature like a modern insulated/HVACd house, they heat as needed. Its an older approach but will work perfectly fine. The walls will have zero problem supporting the roof as it is incredibly light compared to modern US roofs.
The round shape sould help against wind. I agree with the lack of insulation though. The heating part could be partially remediated with radiant heat. With a heavy masonry stove instead of a simple wood stove.
