We have a large opening in between our dining and living rooms sort of like the one above. I'm pretty sure pocket doors must have lived there at one time, but to fulfill on the desire for "open floor plans," they were most likely removed during an earlier renovation.
Throughout our loving restoration of the old place, I've tried to pay attention to the details and give our home a little love. All of the original moulding was removed, so this Spring we're going to be adding a bunch of it all around the house. Until then, I am liking this idea of treating a big, gaping doorway sort of like a window. Dressing it up with curtains and nice hardware is a great way to add some personality and warmth. You can see above how it would work on both sides of the doorway also. Loving the ebonized floors and subtly patterned lamp shades too...note to self: always more details to be considered.
