Hey, SBG - 5 days and $10K for walls & floors sounds good. The developers should be all over it for 3 story duplex and cottage projects. But, I don't think I've seen any new tilt up detached residences. It's all stick frame around here. Or are these concrete homes undesirable despite the construction savings?

I can't predict viability of this emerging technology. I just like the idea of it. Freeform buildings, customized per owner whim. CAD on the fly. And the gantry track can be repurposed as a neighborhood transit system (more likely a kiddie ride or lawn mower impediment).
