According to State Farm, completely rebuilding my apartment is would be 1/7th of what I paid for it, and that's with NYC union labor.

There's a reason that crackhouses in Vancouver cost $1 million, and it's not because they're made of gold. You need to build density to reduce the share of land cost per dwelling, anything else is a gimmick.

I'm not sure 3D-printing houses will do much for their final prices. Actually putting materials on top of each other is not an overwhelming fraction of the total cost.

Why would a 3d printed house be superior to factory constructed modular housing?
