Love this idea of using space between the wall studs for storage.but use a sliding barn door style door! Living room is to the left and kitchen on the right. Photo taken from dining room table. This is a short dividing wall between rooms.
Utilize space between studs to add shelving. This would be ideal down a long hallway. Add glass shelves and lighting for display or cabinet doors to hide stored items. Install adjustable shelves to allow for easy changes.
Add storage to small spaces by creating recessed wall cubby niches between wall studs. Perfect for a bathroom or entryway. DIY tutorial on how to make it, including links to the beadboard and crown molding shelf, from Pregnant.with power tools.
