In all of these demos, they never show you the resulting bathroom, shower, or kitchen. It's always "here's a shell we made". I'd like to see the finished house, with fixtures in place and working.

While am generally a 3d printing skeptic I feel it's not quite a fair take. The bulk of a house (and its major cost component) is the structure. So this could be useful even if it can't print you the bathroom and the fridge.

How well it going to work in practice is another matter (and here's where am skeptical).

they show you the kitchen and a shot of the bathroom sink in these pictures, actually. it's just so minimalist that it's not that obvious. not quite to my taste but that's in part because they just want to show off the building itself.

really, though, you can finish them like any other house; there's nothing special about the kitchen, bathroom, or walls that precludes it.

aside from the striping, i imagine there's not that much different about building internal structures into a house like this than there is into more traditional rammed earth housing.

The structure also has to accommodate those features. They’re not wholly independent.

I like the idea. Have these been put through stress tests? i.e. Wind tunnels, simulated forest fire, floods, earthquake, cold / hot weather, powder actuated projectiles and how do they compare to traditional wooden framed or steel framed homes? What is the thermal insulation rating? I would expect thermals to be pretty good. I've seen similar designs using aircrete [1] and those are fire-resistant. How strong is this compared to aircrete?

I assume it has the same longevity as things built out of mudbricks...

Cool idea, the lack of discussion of longevity seems pretty glaring. While we would all love to not cause any stress on the environment, we also have to live though heavy rains, snow, and wind. Maybe this structure is designed for dry environment and can with stand a couple of rains a year. >>The architect studied how a building’s shape could impact its efficiency, in relation to its climate and latitude. hopefully someone also studied materials the house is made of, because that seems pretty important. Dirt is a very good insulator of both heat and sound, so maybe they could build something like this a put some sort of shell around it, like siding on current houses, to protect it from weather.
