After reviewing hundreds of people's drawer builds I decided to go for it. At least with a box. The plan is to leave it in for a week or two and see how it work's for my wife's daily driver tasks, groceries, and so forth.
I built the box out of 3/4" birch for the top and bottom, 1" plywood for the sides. The 1" and 3/4" seem overkill so I'm debating redoing the whole thing in 1/2" birch.
If the box checks out then I'll go from there.
1) Wings to fill in the sides.
2) Platform over middle row for sleeping
3) Regular drawer on the left
4) Double slider kitchen drawer on the right
