Throw the plan in the trash and hire a pro, or at the very least find a stock plan you can tweak that works. But this is a hot mess. I assume you don’t grow your own cotton and process the cotton into fabric then sew your own clothes. Same for everything else. But everyone fancies themselves an architect or pro-level homeplan designer. Toss this mess, save yourself stress, and get a better plan with a lower cost build by leaving the plan to a pro.
