Make a Base out of 2×4’s : Cut 3 pieces to 19 3/4 inches and 2 pieces to 30 3/4 inches. Create pocket holes in the 3 shorter pieces and attach them to the longer piece (starting with creating the box and adding the middle piece after). Attach using wood glue and kreg screws.
Make the frame of the Tower using 3/4 inch plywood: I had home depot cut the plywood sheets to size for me or you can use a table saw. The side pieces are 87” tall by 22” wide and our ceiling is 8 ft. tall. You will need to add inches for a taller ceiling. The top and bottom pieces are 30” by 22”.
Creat 5 pocket holes on the top and bottom of the side pieces (so 20 total). Use wood glue and a corner clamp to create a perfect 90-degree angle between a side piece and top/bottom piece. While the clamp is in place add Kreg screws to the pocket holes.
Add supports to the tower. Use the scrap pieces of plywood to cut 2 6”x 28 1/2” pieces and 4 3”x28 1/2” pieces. Add pocket holes to the ends of the 3” pieces and the ends and one side of the 6” pieces.
Using wood glue and Kreg screws for the pocket holes attach the 6” pieces to the top and bottom of the frame. Make sure the pieces are inset and flush with the sides/top and bottom.
Attach the 3” pieces using the same technique. Space the piece by measuring 18” from the bottom to the top of 3” pieces like in the photo. these pieces will support the shelves so the spacing is important.
Add a back to the cabinet using 1/4 inch plywood. Use a piece 30” by 87” and nail it to the back of the cabinet using brad nails.
Attach the frame to the base and wall studs, in the corners, using the drill, countersink bit and 2 1/2” screws.
Add 4 pocket holes to the sides of the Shelf pieces of 1/2 inch plywood 28 1/2” x 22”. Set the shelf on top of the pack support piece, level the shelf, and attach the shelf to the sides of the tower using Kreg screws through the pocket holes on the underside.
Add the Trim. Cut 1×2’s into two pieces 88 1/2” long. Attach them to the front frame using brad nails.
Cut 2 1×2’s to 27 3/4” and attach them to the top and bottom of the frame using brad nails.
Cut 2 1×2’s to 88 1/2” and attach them to the side using brad nails.
Cut 2 1×2’s to 19 1/4” and attach to the top and bottom of the side using brad nails.
Wrap the bottom of the tower with baseboards.
Wrap the top of the tower with baseboard.
Add trim to the shelf fronts using 1×2’s cut to 27 3/4” and attach using brad nails. Make top of the trim piece flush with the shelf.
