"It is odd to see those same building styles you would find in downtown San Francisco or a city in Germany in China."
You should find it no less odd to see such building styles in San Francisco. Western architecture is as un-American as it is un-Chinese.
By the way, about the last building:
The larger North Building is called Sassoon House. The building was built by Sir Victor Sassoon, of the Sassoon family, which built a Shanghai business and real estate empire in the early 20th century. He was a British Sephardic Jew of Iraqi origin, educated at Harrow School and Cambridge University. His family owned the trading company "E.D. Sassoon & Co.", which managed extensive business interests in Bombay, Hong Kong, and Shanghai.
