Answer:
Expensive Materials
Explanation:
Houses built using expensive and extremely good quality materials are more expensive than houses that aren't quite the sight for sore eyes, and aren't that good quality but still liveable, are obviously going to be more expensive. For example, a 2000 sqft house could cost 500K USD for medium quality products and materials, but that same house, but with marble, gold, and very good materials would cost probably 800K - 1.2M USD. Materials' looks aren't that important, and the quality doesn't have to be astronomical either, the home just has to be livable.
There are several ways in which we could justify this statement, but also many ways in which we would be able to challenge it.
In terms of support, we can argue that this was the case because the cultures of America did not have any significant contact with the cultures of Africa or Oceania until the arrival of the Europeans. We can also support this by the fact that the Andean cultures and the Mesoamerican cultures had no contact with each other.
However, there are several factors that show that this was not the case, or that the claim might be exaggerated. For example, we know that many groups in Africa had extensive interactions with each other. For example, the expansion of the Bantu that took place over large regions in Africa. Another challenge could be the extensive contact that many Mesoamerican groups had with each other.
