Why is it that something that has been around for decades, simple mill work and even CNC millwork, is now being equated as an analog to printing when in fact it is in no way analogus to printing?
Also, where are all of the CNC milling going to be located so that "almost anyone" can get their "printed" parts?

Their system reminds me of the old barn where i grew up.
There they used whole logs that they cut notches into and drilled holes thru. Then they lined up the notches and holes, and hammered in wodden plugs. And this basic construction stands to this day.

@Rt1583: If you look on Kickstarter, you will see that very low cost CNC milling machines that can cut out a 4x8 foot sheet of plywood are becoming a reality. This is the CNC innovation that will make it practical. It is so inexpensive that it could be justified to build just one house on site. This is a really good idea whose time has come.

Uh yeah, the Chinese have made buildings using thru-pegged mortise-and-tenon joints for many centuries. And modular housing already exists. Milling all of these parts would make a huge amount of waste plywood, and most people can't even follow instructions to build and IKEA bookshelf.

So each part will be a one-off custom-manufactured on a CNC mill?
This is basically the exact opposite of mass production. Expect prices to be the exact opposite of affordable.

I see your Point of view Jon A. But Labor is 60% of construction. Making a system that can be assembled by the homeowner; meets local code and can be signed off on by local building inspector before the purchase is made is highly attractive. As for location and availability (Rt1583), they could set up franchises in local locations. Wikihouse could concentrate on the software and the franchises could concentrate on helping the customer select the right configuration for local codes and supporting the homeowner in the assembly process.

This type of mass printing may lead to the critical flaw which would be the knowledge of how to correctly build upon the foundation.The house may be assembled anywhere from a city to the woods ,but without an understanding of how foundations work ,disaster may follow.Will this be explained properly.

I have been in the DIY kit homes industry for the last 5 years, whilst I have no problem with the design, it seems very complex as we can put one of our Austen Backyard Cabins up in 6 hours and ready to be lived in. google Cabin Kits Galore if you would like to see what I am talking about.
The biggest problem is council. they are legally allowed in NSW Australia under 20m2 without approval, but if you wish to put a bed in them the cost goes sky high as the council wants to make its $.
Great idea for disaster relief but these disasters happened a long time ago and there is the ability of cabins like ours that had already been built and living in for relief as soon as it happened. Keep on truckin, but government planning agencies will be the problem.

It is not the newness or novelty which matters. It is the use of materials, bringing together of readily available methodology and innovative organisational structuring. At last - something which can be adapted for construction and use in poor or disaster struck countries.
I am thinking ahead to when waste plastics are built into these new structures - insulation, frame, furniture, bedding - precipitation and condensing water collectors, the list is endless. It is about time that other designers built upon this by contributing additional possibilities - all minimal cost. When!! Hopefully before I go.

There are a plethora of cheaper, low-tech, alternative building techniques out there already, none of which make economic sense once you pay for approved materials that don't make your architect/engineer/lawyer nervous.
