This corner cabinet is built to standard base-cabinet proportions — 34-1/2" tall by 22-1/4" deep, with the usual 4-1/2" x 2-1/2" toekick — so it can drop into a run of matching base cabinets rather than standing alone as a mismatched corner piece. Both back pieces get 3/4" plywood, deliberately overbuilt for a spot that's never seen, with pocket holes drilled along the back edges early so the sides can attach in later steps.
The bottom shelf sits up 5" from the floor — use the 5"-wide plywood spacer pieces to set that gap consistently while attaching it, and drill pocket holes along the underside of the side edges before the sides go on. The top is cut from scrap left over from the back pieces rather than a fresh sheet, with the pie-cut front cut out of that same scrap — it needs to start at least 34" x 20" before the angled cut.
Build the face frame separately, then attach it to the front through the predrilled pocket holes, overhanging the sides by 1/4". This cabinet does not get the same 1/4" plywood backing tack as the other base cabinets in its matching run — when installing, use scrap plywood blocking where the cabinet attaches to the wall studs instead. Doors should match the height of the other base cabinets in the run and be cut 3/8" wider than the face frame's inside opening.

Drill 3/4" pocket holes along the back side edges of both back pieces so the sides can attach in later steps.
Attach the bottom shelf with a 5" space underneath, using the base support pieces as spacers to set the gap. Drill 3/4" pocket holes along the underside of the side edges.
Attach the sides to the back and bottom, keeping a 5" gap under the bottom shelf on the sides. Drill 3/4" pocket holes along the sides for the face frame.
Cut the top from scrap left over from the back pieces, cutting out the pie-cut front. Drill 3/4" pocket holes facing forward on the front pie-cut edges for the face frame.
Build the face frame separately with 3/4" pocket holes, pocket hole screws, and glue. Attach through the predrilled pocket holes with pocket hole screws, overextending the sides by 1/4".
Hang the cabinet door with concealed euro-style hinges, matching the door height to the other base cabinets and cutting the door 3/8" wider than the face frame's inside opening.
Sand all surfaces and finish with primer and paint or stain and poly. When installing, use scrap plywood blocking at the wall attachment point, since this cabinet has no 1/4" back panel tacked on like the others in the run.
