Barn Doors
Many people have taken the classic barn door from the farmhouse/ranch-style homes and incorporated it into their own designs. This may be used as a main room or closet, but it’s best not to do so in this day and age.
It might have started as a one-of-a-kind concept, but by the time so many people did it, it’s become just another fad. Maybe that goes with the rest of your décor, or perhaps you should simply add an actual door to that door frame.
