When you're ready to rest your bones, the cabin quickly unfolds to 480 square feet of living space, with a range of creature comforts.
well mine(without the pullout middle section which adds over 100 square feet) is almost exactly this dimension..ten feet by 48 feet.
and Grimm has some points. This might be good for relatively temperate places like The Netherlands or New Zealand..but places with climate extremes? I could see my breath in my place when the furnace was on the highest setting and it was -18 F out this winter..and they are metal ovens in the summer-you MUST have AC..or you will roast.
-you get used to the rain on the metal though..and it gets kind of comforting in a cool kind of way.
I think for some of the uses like combined for cheap student housing, vaca places, hostels, and even temporary housing for homeless or such, they have a niche. Just not in Manitoba or some Arizona desert.
If they really could refurbish, insulate, combine two of them together, and anchor them securely,-all at a reasonable price, they might make good affordable housing for people with low incomes. Two or three of them together (at eight feet wide and eight and a half feet tall, and 40 feet long, three would be almost 1000 square feet) would be a decent size for a couple or a single person with a lower income.
**And then the stigma of the 'trailer park' would be minimized due to the worse stigma of the 'shipping container park'
