I’m intensely into the idea of prefabrication of my house in a factory because I can assemble in ten parts.
Ten parts if the roof is only one piece, which technically would fit on a truck without a special-special permit (just a normal special one), but it would probably be too complicated. So I would cut it in 3 and make HHH a 13-piece, Ikea-like puzzle.
Those 13 pieces/modules (structure, partitions), appliances (faucets, switches, machines) and some furniture, bam. Done.
Concrete is a pretty difficult material to work with. Temperature influences its behavior wildly, for instance. Having a controlled environment in a building VS being in the afternoon sun in southern California with a concrete mix a bit dry and cranky workers is not the same pain at all. The added cost seems to be worth it in a few ways.
Pretty locked on the design. I need to create the VR version next. I’m a bit behind.
