I.AM.IMPRESSED!Merry Christmas, y'all. Interesting thread here. I love how versatile pallets can be for building, not to mention cheap. From small to large projects, a great resource to build on the farmstead quickly and (fairly) easily.
My favorite thing about pallet building (other than cost effectiveness) is that, with some planning, they piece together like a puzzle when building larger structures like sheds or miniature barns.
I'm a slow one year+ into constructing a 10'x12' workshop. I added on a pallet half-wraparound patio, too, which makes for a nice space to pull my saws out onto.
A quicker recent project was a hay shed. Made from a few pallets and some T1-11 siding. It comfortably holds five bales, but a sixth can go direct in front of needed. The structure still needs a barn door to cover it up from rain and wind and snow (and my Rhode Island Red who likes to lay her eggs in there and mess up the straw stacks).
I am working on the layout for another big project: an 8'x12' mini barn to house my Dexter cows, and probably my mini pigs, too, as I'd love for all of them to pasture together. I have the pallets, and laid out on the ground to map out the work, but now need to connect them together with 2x4s and raise the walls!
