What are you looking for? There are so many different designs. So far all I see is not cardboard

Are you thinking built in? (need to be south of here .. 49.5N)
what latitude?
how much sun? (we have many cloudy days, but sunny days happen too)
how fast do you need to cook?
  - faster cooking (400F) needs more aiming and complexity and or automation.
  - slower cooking (200F to 250F...) means simple and less work, but more scheduling.

I have built both an oven and a cooker (heats a pot directly) but cardboard. Either one could be made of plywood. I haven't measured the cooker, but the oven gets to 275F or so using reflectors. Enough to make bread.... but not crusty artisan styles   Things just take longer. Making something out of cardboard is cheap and tells you what you can expect to get from solar cooking and if it is something you will use enough to put the work into a more permanent solution. Right now I am designing a wood cased one, but I am pretty sure I will be the only user unless I make it very easy to use.
 
You frighten me terribly. I would like to go home now. Here, take this tiny ad:
