You can use either 3/4" pocket holes and 1 1/4" pocket hole screws and glue or 2" screws to attach. Keep outside edges flush and square.

TIP: If you are using pocket holes, go through the entire plan and mark all pocket hole locations and get drilling before any assembly.

Next, add the drawer guides. Take a second to ensure the drawer area is square, as you will only have a 1/4" of total play around the drawer.

Attach top of storage box to sides.

Take your time drawing carefully out your end patterns. The ends do not have to match my suggestions, but they do have to match each other. Once you have one cut, use it as a pattern to cut the other. Clamp the two cut ends together and sand all rough edges until the two match. Then attach to the center storage area with screws and glue.

You can make your tabletop from just about anything. The best solution is joining hardwood boards together on the underside with 3/4" pocket holes and 1 1/4" pocket hole screws. Another option is to use 1/2 sheet of hardwood plywood, cut to 47" x 33". Then attach edge to edge 1x2 frame around all sides to create a sturdy and decorative wood edge to the tabletop. Would be beautiful in Purebond Plywood for sure!

Now the tabletop should just fit right over the base. Attach through sides into the 2x2 supports with 2" screws.

For this drawer, I just went the simplest possible route, figuring the drawer is not high use and wanted to keep it simple. This drawer is just a 1x4 box with plywood on the bottom.

Make sure the drawer fits in the opening. I like to rub the drawer bottoms with candle wax to make for a smoother slide.

And then just position the drawer faces over the drawer boxes, shimming so there is an even 1/8" gap all the way around, and attach with 1 1/4" finish nails. Then also attach from inside with 1 1/4" screws. TIP: Attach hardware first to drawer face so you don't have to drill through a second layer of 1xs to access the hardware screw - depending on your type/style of hardware.
