Sunroom almost exactly. either this floor or repeat entryway floor. All metal windows and doors throughout, simple ceiling, chandelier, fireplace punches through from living room. (some thick metal areas around window/door frames)
Love this cottage look for a guest bedroom. I see our 2 twin beds on either side of the room with floating shelves over both beds for symmetry, matching night stands & a small rug in between to unite the space.
