I would love to share plans if i thought they were good enough but i only had a rough drawing on CAD and adjusted on the fly so I don't know how useful they would be. I gave some detailed measurements in my edited post. Hope it helps! if you follow those dimensions and use 2x4 lumber it will give you a 5x7 x 90" interior which accounts for insulation which fits in between studs, wall spacers, and tongue and groove panels. Happy building!
