We had the door included in the carpenter package, so I actually don't know. In the rooms with extra height, like the entrance area, we have a barn door as a divider to the children's cloakroom, but otherwise most doors are ceiling-high. We also have a few sliding doors, which you can't see at all when they are open.
Thank you very much... The kids were allowed to choose themselves, the walls are painted with magnetic paint and the floors are made of liquid cork; they were practically poured in.
