I'm no longer imagining siding -- I'm looking at it!
So for those of you who are interested, it is a rain screen that sits off the house on furring strips and essentially protects the stuff underneath from, well, rain. Among other things. It is sawn from spruce trees on my site that were cleared by man and the gods earlier in the project. It extends above the walls to provide safety rails at roof level, which is an accessible green roof -- or will be some day. Currently it is accessible gravel and there is no place on earth the kids would rather be!
