This was my first time building real cabinets. I designed them as a custom fit for the space using other cabinet plans as a guide for the cases.
The doors and drawers are birch veneered plywood. I bought a few sheets that matched and lined them up to get the grain patterns to be consistent. The sheets had a beautiful "flame" pattern that I took advantage of. The top of the workbench is 1/4" hardboard screwed onto 1 1/2" pressboard. The top is rock solid, and I can replace the tops whenever they get too beat up.
For the cabinet and drawer handles I wanted something that was appropriate for a garage workshop. I ended up creating the cabinet handles from spikes - they look like giant nails. The drawer handles are hammerheads. I bought inexpensive hammers at Home Depot and cut off and mounted the heads. They look great and are very comfortable to use.
I also covered the exposed walls with peg board to provide plenty of room for hanging things.
