Two rooms with a connecting door have different floor coverings. There is a narrow threshold strip at the join. How should this strip be placed relative to the door?
It is clear that, with the door closed, the flooring of one room should not be visible from the other. My gut feeling is that the room into which the door opens "owns" the door and that the join should be immediately underneath the outside of the door thus defined, hence half of the threshold strip would be under the door and half in the room that does not own it. However, what is correct?
