Ken and I not only looked into it, but we joined the straw bale forum many years ago. We also took classes in alternative building at the local college. Ours is designed and we just know that for us it's absolutely perfect. But life got in the way of the building, as it does with so many other things. We haven't given up on the dream - just postponed it.
SB homes are in use all over the country. There are things that can be easily done to make them successful no matter where they are located. There are many of them in Washington State and Oregon, and if any places in the country know rain and moisture issues those would be the ones. Early settlers in the Sand Hill area of Nebraska used hay bales to build their homes and remarkably some of the them are still standing, despite missing roofs, clay slurry for surfacing, tornadoes, heavy snows, and being totally load bearing structures rather than the way most folks do them today. Modern straw bale houses are usually built with a frame and straw bale infill but many old school builders still prefer to build load bearing buildings. A straw bale grocery store in Glenrock, Wy, built in the 40s, is still open. There are a few homes in Cody, one in Greybull, and one in Powell, all within 50 miles of us here. And those are just the ones I know about and have seen and personally toured.
Okay, looks l like I hijacked another thread. <sigh> So let me pull myself back on topic by telling the OP that I think the cattle panel "awning" will work very well, and once the cattle panels are transported to the building site the hardest part is done!
No need to worry about hijacking, lol. I love watching where a thread will go when diverse people contribute. BTW, straw bale houses look so cool!
