I love the idea of building on site with site materials. Rammed earth housing - is an example. Mouldings/hoardings are brought in, but if you do sections at a time, you don't need that much. Labour is the intensive part. If you could get a machine to print with materials on site, or tapping into the waste stream that would be great. Not so happy with the concrete here. I'd rather a more friendly aggregate. An adobe tube house isn't a far cry from this - but looks more eco friendly. I'm sure you could machine much of that building process.
