You're dealing with many different issues but overall, an open shed if often not required to even have sprinklers. I know we like to put sprinklers on everything but there are just times when there is no Code direction to do so regardless of what we think should be done. So if there's no Code, AHJ or Underwriter requirement to do so then you've got no way to justify it and the owner isn't going to just volunteer funds to protect something that's not required to be protected. End of story, go to the lake and drown some worms, your work is over.

The last shed structure I dealt with was next to the water where wind could be an issue. However, a shed without walls, I would think, have very different burn characteristics than an enclosed space. The structure is more like a giant ceiling cloud that a room. Are you going to get a significant flow of fresh air at floor (or fire) level to replace the hot air escaping all sides around the roof? If this going to increase the intensity of the burn? Haven't done any research, but those are just questions.
