Today I’m sharing my under-the-stairs shelving build plans for the craft/cat/storage/wine/etc. closet. I designed and built these shelves specifically to store my DecoArt paints, so the sizing and measurements are based on the typical DecoArt paint can. That said, you can easily take these plans and adapt them to fit any under-the-stairs storage closet. You can make the shelves deeper to store more things, or you can build more space between each shelf. The idea can be easily customized based on whatever space you’re working with.
I shared my craft closet makeover inspiration a few days ago, and here are the two photos I’m modeling my under-the-stairs paint shelving after. In this one, I love how tall and shallow the shelving is. It doesn’t take up that much space, and you can easily see what you have without digging around.
In this one, I love how you can see the top of each paint:
Before Pics: A Quick Reminder…
Before we get started on the tutorial for the shelves, here’s a quick reminder of the before pics. As you can see, my paints are all over the place. I have to dig around to see what I have, and those two boxes on the floor are also full of paints. Plus the closet is just a nightmare scenario and it’s hard to get to anything.
After I emptied the closet, I got to work building my shelving!
Here’s what I used…
(Affiliate links below. Thank you for supporting my blog!)
- 1×4 lumber
- Kreg Jig
- 1 1/4 inch Kreg screws (here)
- 2 1/2 inch screws
- Corner braces and 1/2 inch screws
- Drill (here’s mine)
- Miter saw (I just brought home this one)
- Sand paper
- Measuring tape
(Remember to wear a mask and eye protection while sanding and working with wood, and wear an appropriate mask while working with paints, stains, and finishes. Follow the directions and warnings from your particular brand. Do not use any tools without proper training, precautions, and supervision.)
First phase…the main shelving piece.
Step 1: Cut all pieces.
Then organize the shelf pieces (not the side pieces) like this:
Step 2: Drill shelf piece pocket holes and attach to the left side of the shelf.
I used my Kreg Jig to drill two pocket holes on each side of the shelf piece. The method of joining via pocket holes makes them super strong, and the last thing I wanted was for my paint shelving to fall apart and have paints tumbling everywhere.
When you’ve finished drilling pocket holes, screw each shelf into the left side piece. The pictures below show all pieces drilled into the left side. You can also see the pocket holes on the top of the unattached (right) side of the shelf pieces.
Step 3: Mark measurements for the right side.
If you set the shelving unit on its side and lay the right piece on top, you’ll see that the shelving pieces are SUPER uneven. That’s just what happens when you are working with cheaper, warped wood, but it’s okay. We’re going to fix that!
Pull the unattached piece down and set it along the attached side. Use a marker to mark where each shelving piece should hit:
Step 4: Attach the right side of the shelf to the unit.
The easiest way to do this is to flip the entire unit over so that you aren’t drilling upside down. In the picture below, you can see that the first few shelving pieces (from the left side) look pretty even. That’s because I had already forced those to line up with the marks I made in step 3 and drilled them into place through my pocket holes.
Some more progress…the first eight shelving pieces from the left side are lined up and attached!
And we’re done!
Note: I ran out of wood at this point. My bad. After we mounted the shelves, I ended up adding two additional shelving pieces on the bottom to maximize space. I recommend against this as it was a little harder to attach them when the unit was mounted to the wall!!
Step 5: Mount the Shelves
And this is where I got angry and had a DIY BREAKDOWN. Because the shelves were supposed to be mounted to this part of the space…
…but our measurements were like, 1/8 of an inch off. Ugh. I was SO angry at myself! I had this fantastic vision, and there was no way I was ripping apart the shelving to re-cut the pieces. So we decided to mount it on the wall you see when you walk in to the room:
We just used plain corner braces to mount the unit. We marked the studs in the wall using a stud finder and did two braces on the top of the shelves and two on the bottom.
Mounted! And I couldn’t resist throwing a few rows of cans on to test it out.
Phase 2: The under-the-stairs part.
Closets under stairs can be so hard to use to their full potential. Since we effed up the measurements and had to move the shelving unit to the side wall instead of the back wall, I decided it would be really cool looking if we continued the shelving up the angle of the stairs. Plus it would help to maximize storage space. To visualize it, I put up some painter’s tape. Although I didn’t end up going quite this route, it will still give you an idea:
And here’s how I made the stair shelves part.
Step 1: Cut all pieces.
…Which is easier said than done. I did a rough cut for the 90-degree lefthand piece and then for each shelving piece, giving myself a few inches to work with as I worked down to more exact measurements. I opted against doing the long slanted piece on the right and instead created a stair-like design using smaller pieces.
Step 2: Start building out the “stair” shelves.
For each stair shelf, I cut a piece that was roughly 4.5 inches (the little piece on the right of the below photos). Then I cut a shelf piece that was the perfect length to fit between the 90-degree lefthand piece and the 4.5 inch piece. I drilled two pocket holes into each 4.5 inch piece and two pocket holes on the end of each shelf piece.
This will make more sense when you see the photos!
I attached each shelf piece to the 90-degree lefthand piece by drilling through the pocket holes on the end of the shelf piece. In the photo below, I haven’t attached this to the wall; I just have it sitting on top of the bottom shelving unit so that I can get a measurement for how long the next shelf piece needs to be.
Make sure to attach a corner brace while you are constructing the shelving. If you look in the photo below, it would have been impossible to drill that corner bracket in once the entire unit was assembled. Also make sure to attach the corner bracket where it will hit a stud. I just used our stud finder to make a mark on the shelf piece.
Continue building out the “stair” shelves until you are done.
Step 3: Attach finished unit to the wall.
Use your drill and 2 1/2 inch screws to drill through the corner braces and into the wall. Make sure you drill into studs because all of these paints are heavy! (There is a second corner bracket at the very top of this unit behind that big can of paint.)
And then I popped my paints on. Yay! I organized them by paint line and color. I have five DecoArt Americana Decor paint lines (Chalky Finish, Satin Enamels, Color Stain, Maxx Gloss, and Outdoor Living) and wanted each paint line to be together. And lest you think I’m a hoarder, I freelance for DecoArt, which is why I have so much of their paint on hand 😉
I’d say I spent a good amount of time just standing in the closet and staring at the shelving. It is SO much better than what I had before, and I can see everything I have! Plus it takes up no floor space and very little space in the closet itself, except for the wall space of course.
What do you think? I think these plans could be easily adapted to fit any under-the-stairs space and help you really maximize your storage space. Make sure to come back next week for shots of the finished craft/storage closet space, plus I’ll be sharing a *HYUGE* DecoArt giveaway for you guys!
