Hi! Thank you very much for the numerous ideas and suggestions!
We have planned the children's bathroom a bit more generously since we have two girls and, based on experience, a bit of space is needed here for girl stuff. :) I would discuss the partitioned chamber with my husband over the weekend.
I believe we originally planned the roof as suggested, but with another provider. The photos really show how great it looks. Where would the price difference be? And did it have to be approved again by the building authority?
Thanks again for the feedback, and of course I'm happy that the floor plan works so well otherwise! :)
