Floor plan: Please give your opinions

Hello, my wife and I have worked out a floor plan together that we both like. I would like to have a few opinions from you, as we can’t quite imagine the space and whether everything is okay.

A few basic data: knee wall 75cm, gable roof with 38 degrees

something is missing ....

Yes, somehow uploading the floor plans doesn’t work.

Insert graphic in JPG format and then upload it. It's not that difficult. :D

hope it works now

Now the basement and upper floor
