Does any out there have a set or sets of standard building plans for outdoor hay bale/foam target hut? We are having a local school build them for us as a project. We looked at the our range and there is no common denominator for of them. Some are over built some are on the ground in pieces. We are looking for something to survive for some time. We use compressed rice straw bales as our back stop. So it would have to hold several bales and have roof to keep the rain out. Further we are on public land so it can not be "permanent". It looks like mounting them on some sort of prefabed concrete deck post might be an idea. Any one else have any thoughts? Thanks for your time.
