Our daughter's closet has a large, blank wall on one side. It was a perfect spot for some added storage and display shelving for her little collections.
Built-in-the-Wall Shelving - Reclaiming Hidden Storage Space
Since this was was not a load bearing wall, I could carve into it without worrying about the roof caving in or adding a header. I sliced open and peeled off the drywall, creating the rough opening.
The studs got cut off with a oscillating multi-tool, below the edge of the drywall.
I wrapped the opening with 2x4s, just to replace some support within the wall. It got screwed into the remaining studs I'd cut off and ended up laying flush with the rough opening.
The basic shelving unit is a box, made from select pine 1x4s screwed together and backed with a piece of beadboard paneling. I made the whole thing a little to tight and had to persuade it into place with a rubber mallet.
I added a couple more horizontal 1x4s with pocket holes and screws for shelving.
A face frame constructed from 1x2s gave the unit a heavier, finished furniture / cabinet kid of look. It also strengthened the shelves and squared up any slight warping imperfections. It got attached with 2" finishing nails.
After some nail hole putty, I gave the unit a light sanding and slightly rounded the edges of the protruding wood. It would help keep the paint from chipping later and hopefully prevent injury if someone was to bump into it after tripping on kid stuff that will surely litter the floor of the closet in the future.
After some caulk and a couple good coats of primer, the piece is done. Waiting for final paint. It will get a gloss white finish. Our daughter is probably going to choose light blue walls as we complete the remodel. Here's a digital preview:
This can be a weekend, do-it-yourself project that's actually not that difficult to do. I've got a ton more step-by-step info on the blog with tools, techniques, and inspiration explained in more detail.
