My wife and I have a couple of acres on the Tilton river in Washington. We currently just do some camping on it but are considering putting up a permanent structure. We want to build a "different" building. We are not limiting ourselves to any possibilities (no treehouses). Round, multi-sided, pie shaped, anything is worth looking at. Water, power, and septic are available. This would be for weekend use and only about 500 to 800 sq/ft. Any ideas from CBN folks would be great.
