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.
I love banquette seating! A great breakfast nook/family dining option that just looks good in any kitchen. Especially in its own little nook with lots of light, and lift-up seats to store kitchen/dining linens.
