These two houses are in full compliance with the relevant national standards
National standards in China are not what they are in most western nations. If manufacturing standards are what were applied these buildings could have been printed with asbestos and leaded paint (amongst other things that would not be allowed here) and the structural rigor of the design and material might well not be what would be viewed as acceptable here.
That said, it is a good start. Now if we could 3d print a house that is safe for human occupation, that would be an even more significant step.
