I think 15 square meter bedroom space is very small. If you want to make a cloakroom, you should make full use of the space. I think we can install a slide from the ceiling and a sliding curtain below, so that we can have 15 square meters of bedroom space when we sleep. If you want to use the cloakroom, you can close the curtains, which becomes another space, that is, the cloakroom.
