Assemble the cube storage units according to the manufacturer's instructions. Measure the width and depth of the assembled units. Ours were 28-7/8"x 23-3/4".
From the 4' x 4' x 3/4" MDF sheet, rip and crosscut the base so that it measures 1-1/2" wider and deeper than the assembled cube unit measurements.
Rout base edges
Using a trim router fitted with a 45º angle chamfer bit, rout a 3/8" chamfer around the MDF base.
Use woodfiller to fill the edge of the base. Sand smooth, prime and paint to match cubes.
Using a biscuit joiner set for #10 biscuits and centred on 3/4", make aligned biscuit slots at top and bottom edges at the back of the cubes. Use carpenter's glue and #10 biscuits to join cubes, clamping until glue dries.
Remove clamps and turn the cube assembly upside down to install base. Glue, clamp and fix base to cube unit using #8 woodscrews and countersink.
