Would really like to do some of the built in/recessed shelves. Use this project for built-in shelves to unlock hidden storage space between the studs in your walls. Install a single, open box of shelves, or install two boxes and add a set of glass doors.
Use Ikea Knuff magazine files as under sink storage holders. Screw a magazine file holder to the inside of kitchen cupboards. Add space to store more bulky items like chopping boards, cleaning products etc.
