Perhaps 6 mm renovation plasterboard can be part of the solution. Bauhaus writes in its product information: "The board's great toughness also makes it suitable for curved shapes and can be bent to a radius down to 300 mm if moistened."
I believe that after much consideration, we are slowly starting to set aside the curved variant. It simply feels too troublesome. Had it been a standalone staircase where we could work with oversized boards, and if the cladding constituted the entire project, not just one of a thousand details and tasks, then maybe. It would have been a fun challenge.
The main approach right now is to build the roof out of three triangles. A skeleton of joists and flat sheets on it. I've tried to find a good design that balances retained space against it not being too faceted. The strings in the picture below show the plan for where the breaks should be. It feels like a sufficient challenge to make it both stable and tight.
Thank you to everyone who has contributed with good and inspiring viewpoints. I might come back with a final result here, but otherwise, the work can be followed in the project thread:
Got a framework up today. Worked hard on both the psyche and the sneak angle. Extra tricky since there's a staircase down to the basement door where you need to maneuver the ladder around. But eventually, everything got in order, and when I try to envision the final result, I'm satisfied with the solution and a bit relieved that we didn't tackle curved boards. Or wallpaper glue and newspaper
Now this special roof is finished! It wasn't completely straightforward, but it worked out in the end. I've put a protractor on the wish list, it would have been good to have.
Now it's just the rest of the project left!
Thank you for your engagement and ideas. Still thinking about how it would have gone with newspaper, chicken wire, and wallpaper paste
Berniberg - would you like to come and do one of those solutions for us too? I have now shown all your pictures to our craftsmen but it will be the first time they try... Come to Stockholm and help us!

Haha, thanks for the encouragement but some things you take on mostly because you haven't done them before. A bit like bungy jumping . But it's fun!
We actually had some nice old plywood pieces that were put together in a stylish puzzle... but my husband didn't like it and we hoped that what was underneath was nice enough to just paint. But nope. But okay, we'll let the guys here do the work with inspiration from you!
