Opinions and tips on our floor plan

There was never any fighting over the rooms between my siblings and me (4 girls and 1 late-born boy). And at first, we shared them in pairs. The kids today can be glad that everyone gets their own room, and the parents decide on the arrangement if the children can't agree. With our plans, that was never an issue... Although the rooms ended up being the same size, the oldest has the bathroom in the attic all to himself for now until we decide (or the middle one decides) to move upstairs, but then into a smaller room than the oldest, but away from the parents with his own boys' bathroom ;) Ç'est la vie!
