I really like these kitchens. In the last one, I love how they made it more of a space to hang out instead of the usual dining area. Set up your rooms how YOU use them, and not what they are "suppose" to be....
Storage is always a issue with small spaces. I always look at pictures for storage ideas. If your space is not as large as say the top picture, you can still do a few shelves in a corner to make it work. Look at every wall and tiny space as a opportunity to store your things !
