I have an issue in that I have three kids and as they get older, the younger two hate sharing a room! They are girls and they fight all the time! I don’t want bunk beds either.
The layout is similar to this. we currently have the large bedroom but wondered if I could swap with them and somehow divide it? Issue is doorways and windows (there is only one although it is a large window.
to give an idea of scale size, I have drawn the single bed that is currently in my other child’s room
