Im not looking to spend a ton of money but am willing to go $200-$400.. I have a lot of 2x4 i think im going to rip down in half for my walls. I also have a bunch of plexi glass to use for the windows along with alum. C-channel for the guides.. Im thinking i want to use plywood on the outside. Good deck stain/paint. I plan on building this in sub assy. pcs. in my shop then assembling it in the woods in spring/summer. What do you guys think? Im also looking for ideas to use my slider up/down plexiglass wndows. Like how to keep them up/down,quiet,etc. Any info? Thanks again
