While this is clearly an impressive technical feat, I can't help thinking of the carbon footprint of creating a house out of concrete, which is notoriously un-environmentally friendly, and difficult to deal with when the structure is no longer required. Hopefully a more environmentally-sound material will be used. There's not a single mention on that page of the carbon footprint of the building method used, and I think it would be interesting to compare physically identical (as much as possible) buildings of different construction (3d printed like this, bricks and mortar, pre-fab wooden/osb panels, etc), particularly when the tag line of the article is: "We Are Building the Future Today."

It is an interesting fact that concrete itself is a carbon sink, and that it mitigates a bit the emissions associated with its production. That said, I agree that it would be interesting to have a independent study of the complete environmental impact of such a building, from its erection to its disposal. I would instinctively expect a smaller impact from this kind of "lean" approach, though this might also create problems due to the economy of scale not necessarily being present.
