This article seems so strange for me, as my experience is that out-of-the-catalogue houses are the first choice now (at least in EU). This is perhaps true here in Denmark, where IMO 90% of houses are catalogue houses that have been customized. That means that a variety of houses on offer from same supplier share same prefabricated walls, same type of insulation ect. Same is true for Croatia, where people usually built hollow brick rohbau (walls+roof) first according to a custom design and then settle in on everything else. Considering the difference in price between roughly the same house in Denmark in Croatia, I would say that manual labour is still a big cost driver, so most of cost reduction will either come from even more modularity (deliver an entire bathroom) or automatization.
