What are the conditions that determine the types of buildings that will be dominant in a city (e.g. skyscrapers, several-story buildings, houses, etc.)?
I guess these conditions include history (how old the city is), location, whether it becomes a trade/business center, etc.
If I try to take example from the real world, I seem to not be able to determine what leads to e.g. a city with lots of skyscrapers.
Seismic activity and climate seem to have little to do with this, considering cities like Tokyo, San Francisco, Sydney and New York. It looks there is not a big cultural factor, because most of the cities with a lot tall buildings are in North America and eastern Asia (but not Europe). Obviously, when the space is not enough buildings will tend to be taller (e.g. Hong Kong). There seems like in North America more eastern cities have larger areas with several-story buildings, while most western cities have a downtown with skyscrapers and houses everywhere else.
I would suppose that older cities will have less very tall buildings, because there is usually less free space for such buildings and making skyscrapers was not possible until the XX century. My other guess is that the development of the tertiary sector (services) will favor gathering people more densely.
It appears that there are so many factors that it's hard to extract a general rule in order to determine what is plausable.
