Not enough wall space for a mail sorting system? Take advantage of behind-the-door storage in a freestanding or built-in cabinet. A decorative metal caddy attaches firmly to a pair of metal strips hung on the back of this door and offers hidden stow-away space for outgoing mail. The metal strips also provide a spot to hang small keys that would likely get lost in a junk drawer.
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.
