Curtains aren't just for showers and windows, either. When I was little, I would've loved a tucked away bed like this one, complete with the potential for privacy.
Have always wanted a cozy-tucked-into-a-wall 'bed' like this! I would love to incorporate this into an office/ guest room combo. I could use it myself for those sneaky afternoon naps or just for a fun & secluded spot to read!
Another unexpected area: dividing and sectioning a small area for privacy. This side room now becomes an extra guest bed (or a place to quietly sneak off to for reading).
