The table that holds all of the boxes. It is made from 2x6 sides and back and a 2x4 front. It has two grooves cut in it to hold the slide in bottom board. One 3/4" down and one 1 1/2" down. This is so I can do a screened bottom board if I want with a solid bottom under that for the winter. I have not done the screened bottom board yet but have the groove for later.
