Perhaps I should have added that the furniture is placed arbitrarily by the draughtsman and is only for visual purposes. Upstairs, only a children's room and a freely usable room are actually planned for later. The bathtub is supposed to be placed directly against the wall. (As mentioned: we are doing the interior finishing ourselves). Under the stairs, there is a storage room for brooms, vacuum cleaners, etc. The utility room has only an exterior passage door and no window.
