Yep it’s pretty common, although most of Taiwan’s houses were thrown up practically overnight, lumps of reinforced concrete .
They are still lumps of reinforced concrete but now they have parking and elevators and security.
That’s debatable, if a big one hit Taipei the shit may indeed hit the fan. Fortunately most of the old gongyu seem practically indestructible. Linked together in rows of reinforced concrete blocks . Usually it’s the mid size towers that seem to fall over from the earthquakes.
All these shiny new apartment developments above, how long do they take to build? For comparison, they just finished a 12 storey apartment block down the road that took 3 years… seemed very slow at every stage from breaking ground to finishing.
