Imagine ordering the customized parts for a house, piecing together their lightweight components and erecting the entire frame; this is the basis of WikiHome.
Borrowing the Hawaiian prefix for "quick," the WikiHome brings the evolving open-source philosophy to architecture, a field typically dominated by professional contractors. Simply select a principle design from hundreds of options, "print" the wood frames using a CNC wood cutter and bolt the pieces together. It gets even better: For the brave, Google Sketchup offers the tools to fabricate your own dream house!
Although it's a step away from the entirely 3D-printed homes, the WikiHome makes the hardest part of construction a three-step process. I, for one, know that I won't settle for a cookie cutter house. If the technology hasn't progressed by the time I buy my first permanent residence, I'll settle for a WikiHome.
