They're building a block of modern flats over the road from me at the moment not too dissimilar to the one in the video. It took 9 months to build the foundations and about 3 months to get the superstructure up (concrete) and another 9 months now doing internal and external decoration. They're now tidying it all up. That begs the question: this product saves the 3 months bit. That is only 14% of the time on such a structure. Is that worth saving? Is it viable on those grounds? Laying a stable foundation (your Lego board) for this must be pretty hard as well to stay in tolerance. Having done the electrics on an old Victorian house, I do rather like the built in conduit system though although another question: do the bricks break their structural strength if you make a whole in the skin to run cables/faceplates)
