After constructing our prototype cabin, which was done on the ground, prior to mounting it on the trailer. My wife remarked that it would make a really nice shed. (She actually still refers to as my shed, just to tease me.)
But after considering it, she was absolutely right.
It would make a great shed!
The thing that makes these special is that they are easily portable. Something especially lacking in shed options for renters & those that need to be able to periodically move the building.
Built similarly to our mobile cabins, they have folding walls. When it comes time to relocate, you simply empty the building, fold it up, and transport it on any flatbed trailer. It can then be setup again using standard deck & shed support blocks in just a couple of hours.
