I keep seeing these multli-closet mudrooms and liking them; they keep it clean, and whereas I don't see myself wanting to open a cupboard door to put away a coat, it's somehow easier to imagine everyone putting away their junk in a closet...of course, I have a coat closet but most of the time my coat goes on a kitchen chair because I'm too lazy to open the closet, so maybe not.
Back wall of garage before enter the house? Simple built-ins to create a mudroom or storage anywhere from a kids room to a laundry room by adding shelves or a deeper bench for sitting. Or instead of custom, buy two thrify store bookcases and paint them, bolt them to your wall and add wainscotting between them. Then pick up a thift store bench and cut it to fit. Add the hooks and you're set.
