So to start I needed to figure out what size would work best, I pushed the hutches over as close to the wall I could without disrupting the door swing. Once the cabinets were in place I found that I could get a pretty good size desk at 66" wide and I figured a depth of 21" was good for what I needed.
To build this we needed a sheet of plywood and 2 2x4's, the plywood would be the top and front pieces and the 2x4's the support.
We first cut the 2x4 boards, first was the long back support, which was cut at 64.5"(to accommodate the 3/4" plywood that would be wrapping the sides). We then cut 5 main support boards, all of which were cut at 18.5" ( as to accommodate the width of the back support as well as the front 3/4" piece of plywood.
