I've been a holder for ages but what gets me is if this Hadrian machine is so fantastic in being able to build a house in two days in Perth now, why don't they have one in operation to cut cost of builds, chugging away to get some operation and maintenance data? Is it cause Australian codes aren't so friendly with single brick builds and the 2-3mm variation in brick alignment too much for cost effective rendering? Why would things be so much better in US where presumably their labour costs are lower than Oz? Just curious as to what they clad these buildings with, externally and internally. If this forum is to also educate re the company on the value of their offering, then it would be nice for an update on the cusp of this potentially big thing in US.
