I'm not sure how much demand there will be for a house in that form factor, but it might make sense as a sort of guesthouse or spare bedroom or similar, an easy way to extend a house's effective space.

Honesty, if you're going to aim to go serious with prefab houses like this, I'd think that it'd make a ton more sense to make the thing modular. Like, sell a selection of prefab "rooms" and then just have the end user hook 'em up. If you do that, I'd also think that you'd want the exterior to be modular, as it's something that people are going to care about.

Second. I am absolutely boggled that Walmart is selling this. It's clearly intended to evoke the iPhone, with the "Apple" name even being on the Walmart site. I'm sure that Apple is not affiliated with this. Apple is litigious as hell about their phone design; at one point, I recall them fighting a case on a design patent that merely covered the rounded corner rectangle.

It's from a Chinese manufacturer. I can absolutely believe that Chinese companies are making infringing knockoffs of all sorts of stuff in China, flying below the radar. But Walmart offering them in the US seems like it'd be a prelude to litigation.
