Cubby Bookcase — Modular Office Collection

Fasten the vertical dividers to the top and bottom boards. Screws hold better than nails, but nails are faster — if using screws, predrill and countersink. Use 2" fasteners and glue throughout, and check for square before moving on.

Attach the back, fastening into the vertical dividers as well as the top and bottom, with 1-1/4" nails and glue. Check for square again — the back is what locks the case's shape permanently.

Fasten the inside supports through the top and bottom with glue and 2" fasteners, and through the sides into their ends. These supports keep everything square and give you something solid to screw a desktop into if you're pairing this bookcase with a matching desk.

Measure and mark shelf-pin hole locations on both dividers of each cubby opening, keeping them level with each other. Insert shelf pins and set the shelves in place — they can be repositioned any time.
