This badge is about building big things.    Build experiences with several styles of natural building that work in a cold climate, with the grand finale being a wofati.

sand badge
(“lloyd list”) do 3 of the following:
   - create 12 adobe bricks 12x6x3
   - make a natural paint and paint a 4x8 area
   - use low grade cob to fill between logs in a wofati - 20 feet
   - create a rock foundation under a skiddable structure to level the structure
   - add 25 square feet of roof (cedar shakes or similar style of wood roof) to a skiddable structure

straw badge
complete all the BBs in the “lloyd list”

Find and assess clay sub-soil for making cob/adobe bricks, try different mixes, keep notes, test them to destruction (smash with hammer, toss in fire, etc), choose best mixes.
   - Try at least 2 different kinds of clay subsoil
   - Try at least 2 different kinds of sand
   - Document at least 12 different individual experiments (adobe bricks). Show your notes.
   - Document your process, how much sand of what type, how much soil of what type?
   - Show shake test results, show mix results. Explain your thinking for the selection process.
   - Make 50 adobe bricks from your best candidate mix.
   - Make 6 minute video detailing your process and showing your final product.

currently, donkey is doing a lot for the straw and wood badges.   I think they are about 90% complete.   We hope to update this wiki page in a few days.

Thanks to Shawn and Kirk "donkey" Mobert for lots and lots of help with this badge!
