*Over the years, I've heard plenty about fabbed housing that is additively fabricated out of solidifying goo, like, for instance, "geopolymer."
*But you hardly ever see any such buildings. Not in real life. The occasional emergency shelter made of sacks of dirt held together with barbed-wire, that's about it. Either this stuff is the vaporware of housing, or maybe it's just hard to find any legal place where it can be built to code; code of course being one vast thicket of throttle-points for the building trades, who'd obviously be in music-biz levels of trouble if walls and roofs were made out of cheap goo.
*They made a lot of claims about geodesic domes, too. All architecture-fiction fans should bone up on the history of geodomes.
*Nevertheless, one can envision oneself inside a fabbed house. Cast sand, basically, cheap as dirt. Devoid of right angles, where all utilities are hidden, even the switches – because everything is controlled by augmented, ubiquitous gestural systems. There's like, some projectors, and, I dunno, maybe a couple of storm-windows, it's just a screaming high-bandwidth feed in there and nothing else – maybe a beanbag, a hotplate and some bubblepak. Completely post-consumerist, open-sourced and shareable. One just lounges around in there paging through one precious legacy analog copy of BLDGBOOK, and chuckling nostalgically.
