They have finished the roof framing when I arrived in the workshop =D I think this is quite a difficult and tricky part. I have spent a lot of time figuring out the angle when I drew the plan. We have 2 different angles for our roof and one main ridge in the middle.

This is a very informative site in German explaining different forms and ways that we can build the roof – https://www.tiny-house-projekt.ch/tiny-house-wissen/dach/
