Honestly, they're mostly different names for the same thing. A portable cabin, prefab cabin, and shed cabin all refer to a factory-built cabin structure that gets delivered to your property ready to use. Different companies and different regions just use different terms.
What matters more than the name is what you're actually getting. Our cabins are Amish-built in the Shipshewana region with the same quality construction as our sheds and garages. They come with features like larger windows, finished interiors (depending on the model), and layouts designed for livable space rather than just storage. People use them as guest houses, home offices, backyard retreats, she-sheds, and hunting camp shelters.
If you're searching online and seeing all three terms, you're looking at the same category of building. The difference is who built it and how well.
