Has hollow core for easy wiring This guy spent $500,000 for this machine to 3D print his entire house. It prints the walls and layers using concrete, which is durable enough to last up to 300 years. The hollow walls allow for easier installation of plumbing and wiring. Steel reinforcements and spray foam add strength, soundproofing and insulation. Because the machine does most of the work, minimal labor is needed, saving up to 45% in costs, and it’s also much faster to build. You could move in within a few days to three weeks depending on the House size.

If you 50-50 mix concrete with Biochar, your home becomes a Faraday cage protecting you against all dangerous electromagnetic waves and any possible Carrington like event of 1859. It also protects against mold, humidity, heat and air pollution.
Saw a $380 per ton price for Portland cement. Biochar costs about the same, but you can make your own if you buy a biochar kiln.
