I imagine there's still all the plumbing, electrical, floors/tiles and other finishings that need to be done that I assume can't be part of that initial 3D pour....as well as of course the initial foundation excavation and landscaping. Maybe a construction industry guy like 4x4 can give us more insight, but I still see a good chunk of trades coming and going. And then on the material side, resource extraction will need to be increased to match the additional concrete demand, plus a whole swath of new machines that have to be built and serviced as a result of this type of construction type. Will that be less carbon intensive?
Price wise, I've looked into prefab houses before, and in the end, there was very little savings when all was said and done. Hopefully 3D can help with that.
Either way it's all really cool, and 3D's influence is growing all the time... but I guess I'm a touch skeptical about how drastically more beneficial it will be or if will change things that much in 10 years. But perhaps it doesn't necessarily need to be drastic or quick...sometimes even small steps are good ones.
