What do you think the smallest size a room can be and still be usable as a bedroom? Would need to fit a single bed, but could get a cabin type with storage underneath.
Only looking at houses online at the moment, I've seen one with the smallest room 2.1m x 2.1m. No photo of the room (unsurprisingly!) I guess it depends partly on the configuration, door position, height of the window. But that does sound very small, doesn't it?
