My house has an open floor plan, so there is no hiding the space under my drafting table. It was filling up with paintings, paint, random supplies, bits of models, and huge dust bunnies. I wanted somewhere to keep my larger watercolors, the ones that don't fit in the file cabinet, and my husband wanted me to clear out under the the drafting table. Thus, the flat file was born.
I designed it to fit under the table, which has a support that goes across the bottom. The cutout in the side is to let the support pass under the cabinet. The handles are brass reproduction Victorian bin pulls I got online from Kennedy Hardware. They're for typography cases. I was worried they would be too tall (the drawers are quite shallow), but they worked perfectly. They were a real pain to put in, though. The screws were too long. If I did it again, I'd get different screws for them.
It's built out of 1/2" maple/birch ply, with birch veneer edging, finished with 6 thin coats of oil-based poly.
Finished and in place under the drafting table, with cat:
