What are the interesting bits?
- The market for these houses is rich Chinese folks; they've grown up thinking of Chinese goods as low-quality. So copy Western "luxurious" neighborhoods—Folks want Western because they want high quality. Don't copy, e.g., Rio's favelas.
- A European architect on their own might not make an appealing house—many Chinese folks care about feng shui, even in a house with Western trimmings.
- Many of these housing developments are almost unoccupied. They sold well—to speculators. That's not just true of these "replica" neighborhoods; that's also true of real estate developments around China in general.
- Some of these luxurious developments are gated communities. (I haven't heard so much about gated communities in China before. I dunno if that means it's a feature only associated with these Western-style places or if I just haven't been hearing about the right things.)
