Interesting case: Seoul. No earthquakes. 20-story buildings everywhere [1]. Construction cranes everywhere.
Still real estate is very expensive ( 13K$ per square meter for something downtown [2] )
The main effect of building so much is that now almost half of the South Korean population lives around Seoul.
