Guest room- Create a nook like this by suspending curtain rods from the ceiling. Put a daybed to be the bed in a small bedroom. Closing curtains allows you privacy to maximize all space for lounge and storage- its ok to have chairs right up to the bed!
I like the idea of taping off a head board design and painting on wall.maybe the guest room? I love black walls! I have black walls in my dining room, I can't wait to try one black accent wall in my bedroom.
