I've had this floating around my mind for a while now and was hoping someone would come along with a success story. A major point for me is access, finding a reasonably secure and non-ugly way of getting stuff in and out of it while keeping weather and evildoers from entering. Careful weatherstripping and one or two rotating key locks per door should work. Other ideas? Entry from one side only, from both sides, from the rear? Full length side opening(s) or just a door along the length of the tallest part? I think I have answers, for myself anyway, but am quite open to suggestions and proven solutions. Also, if anyone has experience with layup of flat stripped panels that would be helpful.
