Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
For this cabinet, I highly recommend a high quality table saw. But you could use a circular saw that cuts a beveled edge at 45 degrees off square. If you do this, you'll need to clamp a board to the plywood and follow it to get straight cuts like I do in this video.
For table saw, set bevel to 45 degrees and rip plywood to a 12 1/2" width, with the 12 1/2" being the longest width on the beveled edge. I highly recommend taking a second to test cut on scrap before committing to cutting the full sheet. The short beveled edge width is 11 3/4".
Once you have these cuts, you can cut the remaining strip 18 3/4" wide for the top, bottom, and shelf. The center is scrap, but you may wish to use it for additional shelves.
From the 18 3/4" wide strips, cut two pieces 32 1/8" long. Then from those pieces, mark as shown in this diagram, and cut out top and bottom. Use this also as a pattern to cut remaining shelf - it can be a little smaller, especially on the pointed corner ends, as it's just the shelf.
For tops and bottoms, drill 3/4" pocket holes as shown in diagram.
Next attach the sides to tops and bottoms. Drill the 3/4" pocket holes first facing forward for attaching face frames in later steps. The adjacent cabinet will cover the pocket holes, and if this is an end cabinet, you will put 1/4" plywood over the end to finish it out.
For bottom shelf, place pocket holes on bottom where they will be hidden. For top shelf, place pocket holes on top where they will be hidden.
Next, build the face frame.
To keep the look consistent, you'll need to rip the 1x3 boards down to 1 1/2" reveal on the short side of the rip, beveling the edge at 45 degrees. Do some testing first to make sure your cuts are accurate. Then build your face frame with glue and pocket holes (3/4" and 1 1/4" screws). Attach to face of cabinet, with overhangs approximately 1/2" on each side.
To install, you always start with the corner first and then work your way around. Corners need to be screwed to a stud in the wall and properly hung. I know these cabinets can get heavy, so make sure you have adequate support. There will be a 1/2" gap between cabinets to give you some "wiggle" room in case your walls aren't perfectly square. Just make sure the face frames line up perfectly. Shim the gap and screw cabinets together from insides. We also like to hide a few screws to connect face frame to face frame for a seamless look.
It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.
