I lived in basically a one room (there were no walls) but the bed room was a corridor away from the living/kitchen area apartment. I made sure to create seperate zones where I did things, although I would often violate the point of these zones (i.e. work on my couch watching TV, rather than at my desk. I feel as long as you keep the areas mentally separately, even if you can't physically seperate the areas you should be okay.
