Wide archway with closets in it. I like this design also between a living/family room and an office/library. When pocket doors or french doors are installed in both walls (on each side of the arch) this creates a lot of separation and privacy. In addition to closets, the inner arched nook can house art niches and/or bookshelves. Domino Magazine photo.
I am envisioning telling friends, "Well, you can always crash on the couch in the entryway"...ha
