As i mentioned before, our master bedroom had two doorways. I think this is because originally the room was built as a den, connected to the garage. Then the garage was remodeled into a living room and the doorway into it was kept. Here are some pics.
Door and door frame taken off
Took stairs off and framed it. It was open to the crawl space for a while – not cool
This isn’t the best pic but we drywalled over, removed wallpaper border, painted a fresh coat of flat white, put the wainscoting over where the stairs were. Now all we need is to fine a matching piece of trim (and clean).
