Build it
01Cut the pieces
Cut the 1x12s and the 1x2:
- A Sides, two at 26¼″
- B Shelves, three at 24¾″
- C Dividers, two at 12″
- D Back rails, two at 26¼″
Watch outEvery shelf and divider must be cut dead square, or the cubes won't close up tight. Clamp a speed square to the board as a saw guide if you're using a circular saw.
02Drill the pocket holes
Set your jig for ¾″ material:
- B shelves: 2 at each end, on the bottom face
- C dividers: 2 at each end, on the right-hand face
The holes in the bottom shelf face the floor, and the rest are out of sight once the bins go in.
03Join the shelves to the sides
Mark the shelf positions on the inside of both sides (A): the bottom shelf flush with the bottom ends, the top shelf flush with the top, and the middle shelf with its bottom face 12¾″ up.
Stand the bottom shelf (B) between the sides, flush with their front edges, glue the ends and drive 1¼″ pocket screws. Do the same with the rest of the shelves.
04Add the dividers
Fit the two dividers (C) into the openings, 12″ apart starting from the inside of the left side, flush at the front. Glue them and drive the pocket screws into the shelves above and below. Line each one up with the divider below it.
TipCut a 12″ spacer from scrap and stand it against the left side or the last divider. Push the next divider against it and every cube comes out the same.
05Add the back rails
Lay the case face down and check it's square corner to corner. Screw a back rail (D) across the back edges at the top and another at the bottom, flush with the ends: three 1½″ screws in each, into both sides and the shelf behind each divider.
The rails keep the case square and give you something solid to anchor to the wall.
06Finish and anchor it
Fill the screw holes, sand with 120 then 180 grit, and paint or stain. Each cube is 12″ inside, so standard 11″ fabric bins fit.
Watch outAnchor it. Screw a furniture anti-tip strap through the top back rail into a wall stud. Kids climb shelves, and a loaded bookcase is heavy.
Build at your own risk. Check every measurement against your own lumber before you cut, test-fit before you glue, and wear eye and ear protection.
