I'd love to do this to the outer entrance of the enclosed porch/mudroom. Dutch door opening up with a screen door for the front door! In the winter a storm door could replace the screen door if done right.
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.
