Built in idea for the dining room door! Oh how I love built ins. Ikea Shelves Into Built-in Bookcases :: I really love this. You could turn any room into a library with this idea. And you don't need ikea for it, either.
Great idea to maximize space in a basement.hallway library going not quite down the center of basement with small sleeping nook off of bookcase side and doorway to another room, maybe a play room/movie room
